Version 3.1.0 (July 22, 2021)

The 3.1 release of OpenEXR introduces a new library, OpenEXRCore, which is the result of a significant re-thinking of how OpenEXR manages file I/O and provides access to image data. It begins to address long-standing scalability issues with multithreaded image reading and writing.

The OpenEXRCore library provides thread-safe, non-blocking access to files, which was not possible with the current API, where the framebuffer management is separate from read requests. It is written entirely in C and provides a new C-language API alongside the existing C++ API. This new low-level API allows applications to do custom unpacking of EXR data, such as on the GPU, while still benefiting from efficient I/O, file validation, and other semantics. It provides efficient direct access to EXR files in texturing applications. This C library also introduces an easier path to implementing OpenEXR bindings in other languages, such as Rust.

The 3.1 release represents a technology preview for upcoming releases. The initial release is incremental; the existing API and underlying behavior has not changed. The new API is available now for performance validation testing, and then in future OpenEXR releases, the C++ API will migrate to use the new core in stages. It is not the intention to entirely deprecate the C++ API, nor must all applications re-implement EXR I/O in terms of the C library. The C API does not, and will not, provide the rich set of utility classes that exist in the C++ layer. The 3.1 release of the OpenEXRCore library simply offers new functionality for specialty applications seeking the highest possible performance. In the future, the ABI will evolve, but the API will remain consistent, or only have additions.

Technical Design

The OpenEXRCore API introduces a context object to manage file I/O. The context provides customization for I/O, memory allocation, and error handling. This makes it possible to use a decode and/or encode pipeline to customize how the chunks are written and read, and how they are packed or unpacked.

The OpenEXRCore library is built around the concept of “chunks”, or atomic blocks of data in a file, the smallest unit of data to be read or written. The contents of a chunk vary from file to file based on compression (i.e. zip and zips) and layout (scanline vs. tiled). Currently this is either 1, 16, or 32 scanlines, or 1 tile (or subset of a tile on edge boundaries / small mip level).

The OpenEXRCore library is specifically designed for multipart EXR files. It will continue to produce legacy-compatible single part files as needed, but the API assumes you are always dealing with a multi-part file. It also fully supports attributes, although being C, it lacks some of the C++ layer’s abstraction.

Limitations:

No support yet for DWAA and DWAB compression during decode and encode pipelines. The low-level chunk I/O still works with DWAA and DWAB compressed files, but the encoder and decoder are not yet included in this release.
For deep files, reading of deep data is functional, but the path for encoding deep data into chunk-level data (i.e. packing and compressing) is not yet complete.
For both of these deficiencies, it is easy to define a custom routine to implement this, should it be needed prior to the library providing full support.
No attempt to search through the file and find missing chunks is made when a corrupt chunk table is encountered. However, if a particular chunk is corrupt, this is handled such that the other chunks may be read without rendering the context unusable

Version 3.0.1 (April 1, 2021)

Major release with major build restructing, security improvements, and new features:

Restructuring:
- The IlmBase/PyIlmBase submodules have been separated into the Imath project, now included by OpenEXR via a CMake submodule dependency, fetched automatically via CMake’s FetchContent if necessary.
- The library is now called libOpenEXR (instead of libIlmImf). No header files have been renamed, they retain the Imf prefix.
- Symbol linkage visibility is limited to specific public symbols.
Build improvements:
- No more simultaneous static/shared build option.
- Community-provided support for bazel.
New Features:
- ID Manifest Attributes, as described in "A Scheme for Storing Object ID Manifests in OpenEXR Images", Peter Hillman, DigiPro 18: Proceedings of the 8th Annual Digital Production Symposium, August 2018.
- New program: exrcheck validates the contents of an EXR file.
Changes:
- EXR files with no channels are no longer allowed.
- Hard limit on the size of deep tile sizes; tiles must be less than 2^30 pixels.
- Tiled DWAB files used STATIC_HUFFMAN compression.
- Int64 and SInt64 types are deprecated in favor of uint64_t and int64_t.
- Header files have been pruned of extraneous #include’s (“Include What You Use”), which may generate compiler errors in application source code from undefined symbols or partially-defined types. These can be resolved by identifying and including the appropriate header.
- See the porting guide for details about differences from previous releases and how to address them.
- Also refer to the porting guide for details about changes to Imath.

First pass of describing versioning and naming of library names (Kimball Thurston 2019-07-25) Signed-off-by: Kimball Thurston [email protected]
Normalize library naming between cmake and autoconf (Kimball Thurston 2019-07-25) installed libraries should follow the following basic pattern: (-> indicates a symlink)

libFoo.so -> libFoo-LIB_SUFFIX.so libFoo-LIB_SUFFIX.so -> libFoo-LIB_SUFFIX.so.MAJ_SO_VERSION libFoo-LIB_SUFFIX.so.MAJ_SO_VERSION -> libFoo-LIB_SUFFIX.so.FULL_SO_VERSION

so with a concrete example of 2.3 lib w/ so version of 24

libFoo.so -> libFoo-2_3.so libFoo-2_3.so -> libFoo-2_3.so.24 libFoo-2_3.so.24 -> libFoo-2_3.so.24.0.0 libFoo-2_3.so.24.0.0.0 <— actual file

(there may be slight variations in the link destinations based on differences in libtool and cmake, but the file names available should all be there) Signed-off-by: Kimball Thurston [email protected]

integer division changed in python3 3/2 -> 1.5, have to use 3//2 to get an int
xrange is no more, just use range

Disable the use of object libraries as a compilation speedup mechanism as a result. Similarly, disable under win32 when building both types of libs to avoid exported symbols in the static libs.

SonarCloud considers strcpy() a vulernability. It was used only in OpaqueAttribute, whose type name was stored as Array. I changed the type to std::string. I suspect this simply dates to a time before std::string was commonly used. (Cary Phillips 2019-07-09) Also, it appears that nothing in the test suite validated opaque attributes, which hold values read from a file when the attribute type is not known. I added a test to validate the behavior, which also validates that the typeName() works when implemented with std::string instead of Array. Signed-off-by: Cary Phillips [email protected]

Commits [ git log v2.2.1…v.2.3.0]

Reverted python library -l line logic to go back to the old PYTHON_VERSION based logic. (Nick Rasmussen, 2018-08-09)
Updated build system to use local copies of the ax_cxx_copmile_stdcxx.m4 macro. (Nick Rasmussen, 2018-08-09)
accidentally commited Makefile instead of Makefile.am (Cary Phillips, 2018-08-09)
update CHANGES.md (Cary Phillips, 2018-08-08)
Added FindNumPy.cmake (Nick Porcino, 2018-08-08)
Add PyImathNumpyTest to Makefile and configure.ac (Cary Phillips, 2018-08-08)
Add ImfExportUtil.h to Makefile.am (Cary Phillips, 2018-08-08)
fix pyilmbase tests, static compilation (Kimball Thurston, 2018-08-09) - python extensions must be shared, so can not follow the overall lib type for the library. - the code should be compiled fPIC when building a static library such that it can be linked into a .so - remove the dependency on the particle python extension in the numpy test - add environment variables such that the python tests will work in the build tree without a “make install” (win32 doesn’t neede ld_library_path, but it doesn’t hurt, but may need path?) Signed-off-by: Kimball Thurston [email protected]
fix OPENEXR_VERSION and OPENEXR_SOVERSION (Cary Phillips, 2018-08-08)
update readme documentation for new cmake option (Kimball Thurston, 2018-08-08) Signed-off-by: Kimball Thurston [email protected]
fix compile errors under c++17 (Kimball Thurston, 2018-08-08) Fixes errors with collisions due to the addition of clamp to the std namespace Signed-off-by: Kimball Thurston [email protected]
add last ditch effort for numpy (Kimball Thurston, 2018-08-08) Apparently not all distributions include a FindNumPy.cmake or similar, even if numpy is indeed installed. This makes a second effort to find using python itself Signed-off-by: Kimball Thurston [email protected]
make pyilmbase tests conditional (Kimball Thurston, 2018-08-08) This makes the PyIlmBase tests conditional in the same manner as OpenEXR and IlmBase Signed-off-by: Kimball Thurston [email protected]
optimize regeneration of config files (Kimball Thurston, 2018-08-08) This makes the config files write to a temporary file, then use cmake’s configure_file command with copyonly to compare the contents and not copy if they are the same. Incremental builds are much faster as a result when working on new features and adding files to the cmakelists.txt Signed-off-by: Kimball Thurston [email protected]
make fuzz test optional like autoconf (Kimball Thurston, 2018-08-08) This makes running the fuzz tests as part of the “make test” rule optional. Even with this off by default, if building tests is enabled, the fuzz test will still be compiled, and is available to run via "make fuzz". This should enable a weekly jenkins build config to run the fuzz tests, given that it takes a long time to run. Signed-off-by: Kimball Thurston [email protected]

README fixes. (Cary Phillips, 2018-08-05)
cleaned up README files for root and IlmBase (Cary Phillips, 2018-08-05)
Fallback default system provided Boost Python (Thanh Ha, 2018-08-03) User provided Python version via OPENEXR_PYTHON_MAJOR and OPENEXR_PYTHON_MINOR parameters, failing that fallback onto the system’s default “python” whichever that may be. Signed-off-by: Thanh Ha [email protected]
fix double delete in multipart files, check logic in others (Kimball Thurston, 2018-08-04) Multipart files have a Data object that automatically cleans up it’s stream if appropriate, the other file objects have the destructor of the file object perform the delete (instead of Data). This causes a double delete to happen in MultiPart objects when unable to open a stream. Additionally, fix tabs / spaces to just be spaces Signed-off-by: Kimball Thurston [email protected]
fix scenario where ilmimf is being compiled from parent directory (Kimball Thurston, 2018-08-04) need to use current source dir so test images can be found Signed-off-by: Kimball Thurston [email protected]

fully set variables as pkg config does not seem to by default (Kimball Thurston, 2018-08-04)
add check with error message for zlib, fix defaults, restore old thread check (Kimball Thurston, 2018-08-04)
PR #187 CMake enhancements to speed up dependency builds of OpenEXR. (Nick Porcino, 2018-08-02)
restore prefix, update to use PKG_CHECK_MODULES (Kimball Thurston, 2018-08-03) previous commit from dracwyrm had made it such that pkg-config must be used and ilmbase must be installed in the default pkg-config path by default. restore the original behaviour by which a prefix could be provided, yet still retain use of PKG_CHECK_MODULES to find IlmBase if the prefix is not specified, and continue to use pkg-config to find zlib instead of assuming -lz Signed-off-by: Kimball Thurston [email protected]
restore original API for Lock since we can’t use typedef to unique_lock (Kimball Thurston, 2018-08-02)
fixes #292, issue with utf-8 filenames (Kimball Thurston, 2018-08-01) windows needs to widen the string to properly open files, this implements a solution for compiling with MSVC anyway using the extension for fstream to take a wchar Signed-off-by: Kimball Thurston [email protected]
fix maintainer mode issue, extra line in paste (Kimball Thurston, 2018-08-02)
Default the python bindings to on (Nick Porcino, 2018-08-01)

fix names, disable rules when not building shared (Kimball Thurston, 2018-07-31)
add suffix variable for target names to enable static-only build (Kimball Thurston, 2018-07-31)
The string field is now called _message. (Cary Phillips, 2018-08-01)
C++11 support for numeric_limits::max_digits10() and lowest() (Cary Phillips, 2018-07-31)
fixes for GCC 6.3.1 (courtesy of Will Harrower): - renamed local variables in THROW macros to avoid warnings - cast to bool (Cary Phillips, 2018-07-31)
renames name to message and removes implicit cast (Kimball Thurston, 2018-07-31) This removes the implicit cast, which is arguably more "standard", and also less surprising. Further, renames the name function to message to match internal ILM changes, and message makes more sense as a function name than … name.
Remove IEX_THROW_SPEC (Kimball Thurston, 2018-07-31) This removes the macro and uses therein. We changed the API with removing the subclass from std::string of Iex::BaseExc, so there is no reason to retain this compatibility as well, especially since it isn’t really meaningful anyway in (modern) C++

Missing symbols on Windows due to missing IMF_EXPORT (Ibraheem Alhashim, 2018-03-05)
Implement SIMD-accelerated ImfZip::uncompress (John Loy, 2017-04-12) The main bottleneck in ImfZip::uncompress appears not to be zlib but the predictor & interleaving loops that run after zlib’s decompression. Fortunately, throughput in both of these loops can be improved with SIMD operations. Even though each trip of the predictor loop has data dependencies on all previous values, the usual SIMD prefix-sum construction is able to provide a significant speedup. While the uses of SSSE3 and SSE4.1 are minor in this change and could maybe be replaced with some slightly more complicated SSE2, SSE4.1 was released in 2007, so it doesn’t seem unreasonable to require it in 2017.
Compute sample locations directly in Imf::readPerDeepLineTable. (John Loy, 2017-04-06) By changing the function to iterate over sample locations directly instead of discarding unsampled pixel positions, we can avoid computing a lot of modulos (more than one per pixel.) Even on modern x86 processors, idiv is a relatively expensive instruction. Though it may appear like this optimization could be performed by a sufficiently sophisticated compiler, gcc 4.8 does not get there (even at -O3.)
Manually hoist loop invariants in Imf::bytesPerDeepLineTable. (John Loy, 2017-04-05) This is primarily done to avoid a call to pixelTypeSize within the inner loop. In particular, gcc makes the call to pixelTypeSize via PLT indirection so it may have arbitrary side-effects (i.e. ELF symbol interposition strikes again) and may not be moved out of the loop by the compiler.
Inline Imf::sampleCount; this is an ABI-breaking change. (John Loy, 2017-03-29) gcc generates calls to sampleCount via PLT indirection even within libIlmImf. As such, they are not inlined and must be treated as having arbitrary side effects (because of ELF symbol interposition.) Making addressing computations visible at call sites allows a much wider range of optimizations by the compiler beyond simply eliminating the function call overhead.

Remove ‘register’ keyword. (Larry Gritz, 2016-09-30) ‘register’ is a relic of K&R-era C, it’s utterly useless in modern compilers. It’s been deprecated in C++11, and therefore will generate warnings when encountered – and many packages that use OpenEXR’s public headers use -Werr to turn warnings into errors. Starting in C++17, the keyword is removed entirely, and thus will certainly be a build break for that version of the standard. So it’s time for it to go.

Adding rawPixelDataToBuffer() function for access to compressed data read from scanline input files. (Lucy Wilkes, 2014-10-22) Changes from The Foundry to add rawPixelDataToBuffer(…) function to the OpenEXR library. This allows you to read raw scan lines into an external buffer. It’s similar to the existing function rawPixelData, but unlike this existing function it allows the user to control where the data will be stored instead of reading it into a local buffer. This means you can store multiple raw scan lines at once and enables the decompression of these scan lines to be done in parallel using an application’s own threads.

Version 2.0 (April 9, 2013)

Industrial Light & Magic (ILM) and Weta Digital announce the release of OpenEXR 2.0, the major version update of the open source high dynamic range file format first introduced by ILM and maintained and expanded by a number of key industry leaders including Weta Digital, Pixar Animation Studios, Autodesk and others.

The release includes a number of new features that align with the major version number increase. Amongst the major improvements are:

Deep Data support - Pixels can now store a variable-length list of samples. The main rationale behind deep images is to enable the storage of multiple values at different depths for each pixel. OpenEXR 2.0 supports both hard-surface and volumetric representations for Deep Compositing workflows.
Multi-part Image Files - With OpenEXR 2.0, files can now contain a number of separate, but related, data parts in one file. Access to any part is independent of the others, pixels from parts that are not required in the current operation don’t need to be accessed, resulting in quicker read times when accessing only a subset of channels. The multipart interface also incorporates support for Stereo images where views are stored in separate parts. This makes stereo OpenEXR 2.0 files significantly faster to work with than the previous multiview support in OpenEXR.
Optimized pixel reading - decoding RGB(A) scanline images has been accelerated on SSE processors providing a significant speedup when reading both old and new format images, including multipart and multiview files.
Namespacing - The library introduces versioned namespaces to avoid conflicts between packages compiled with different versions of the library.

Although OpenEXR 2.0 is a major version update, files created by the new library that don’t exercise the new feature set are completely backwards compatible with previous versions of the library. By using the OpenEXR 2.0 library, performance improvements, namespace versions and basic multi-part/deep reading support should be available to applications without code modifications.

This code is designed to support Deep Compositing - a revolutionary compositing workflow developed at Weta Digital that detached the rendering of different elements in scene. In particular, changes in one layer could be rendered separately without the need to re-render other layers that would be required to handle holdouts in a traditional comp workflow or sorting of layers in complex scenes with elements moving in depth. Deep Compositing became the primary compositing workflow on Avatar and has seen wide industry adoption. The technique allows depth and color value to be stored for every pixel in a scene allowing for much more efficient handling of large complex scenes and greater freedom for artists to iterate.

True to the open source ethos, a number of companies contributed to support the format and encourage adoption. Amongst others, Pixar Animation Studios has contributed its DtexToExr converter to the OpenEXR repository under a Microsoft Public License, which clears any concerns about existing patents in the area, and Autodesk provided performance optimizations geared towards real-time post-production workflows.

Extensive effort has been put in ensuring all requirements were met to help a wide adoption, staying true to the wide success of OpenEXR. Many software companies were involved in the beta cycle to insure support amongst a number of industry leading applications. Numerous packages like SideFX’s Houdini, Autodesk’s Maya, Solid Angle’s Arnold renderer, Sony Pictures Imageworks’ Open Image IO have already announced their support of the format.

Open EXR 2.0 is an important step in the adoption of deep compositing as it provides a consistent file format for deep data that is easy to read and work with throughout a visual effects pipeline. The Foundry has build OpenEXR 2.0 support into its Nuke Compositing application as the base for the Deep Compositing workflows.

OpenEXR 2.0 is already in use at both Weta Digital and Industrial Light & Magic. ILM took advantage of the new format on Marvel’s The Avengers and two highly anticipated summer 2013 releases, Pacific Rim and The Lone Ranger. Recent examples of Weta Digital’s use of the format also include Marvel’s Avengers as well as Prometheus and The Hobbit. In addition, a large number of visual effects studios have already integrated a deep workflow into their compositing pipelines or are in the process of doing so including:, Sony Pictures Imageworks, Pixar Animation Studios, Rhythm & Hues, Fuel and MPC.

In addition to visual effects, the new additions to the format, means that depth data can also be assigned to two-dimensional data for a use in many design fields including, architecture, graphic design, automotive and product prototyping.

Detailed Changes:

Updated Documentation (Peter Hillman)
Updated Namespacing mechanism (Piotr Stanczyk)
Fixes for succd & predd (Peter Hillman)
Fixes for FPE control registers (Piotr Stanczyk)

Numerous minor fixes, missing includes etc

Version 2.0.0.beta.1 (June 15, 2012)

Development of OpenEXR v2 has been undertaken in a collaborative environment (cf. previous github announcement) comprised of Industrial Light & Magic, Weta Digital as well as a number of other contributors.

Some of the new features included in the Beta.1 release of OpenEXR v2 are:

Deep Data Pixels can now store a variable length list of samples. The main rationale behind deep-images is to have multiple values at different depths for each pixel. OpenEXR v2 supports both hard surface and volumetric representation requirements for deep compositing workflows.
Multi-part image files With OpenEXR v2, files can now contain a number of separate, but related, images in one file. Access to any part is independent of the others; in particular, no access of data need take place for unrequested parts.

In addition, OpenEXR v2 also contains platform independent mechanisms for handling co-existing library version conflicts in the same process space. (Currently implemented in IlmImf)

Finally, a reminder that this is a Beta release and potentially incompatible changes may be introduced in future releases prior to the v2.0.0 production version.

Please read the separate file for v2 additions and changes.

Detailed Changes:

Added git specific files (Piotr Stanczyk)
Updated the so verison to 20 (Piotr Stanczyk)
Initial use of the CMake build system (Nicholas Yue)

Version 1.7.1 (July 31, 2012)

This release includes the following components:

OpenEXR: v1.7.1
IlmBase: v1.0.3
PyIlmBase: v1.0.0 (introduces a Boost dependency)
OpenEXR_Viewers: v1.0.2

Of particular note is the introduction of PyIlmBase. This module forms a comprehensive set of python bindings to the IlmBase module.

In addition, contained in this release is a number of additions to Imath as well as a minor tweak to Imath::Frustrum (for better support for Windows platforms) as well as other minor fixes, including correction for soname version of IlmImf.

Version 1.7.0 (July 23, 2010)

This release includes support for stereoscopic images, please see the adjoining documentation in the MultiViewOpenEXR.pdf. (Many thanks to Weta Digital for their contribution.) In addition, we added support for targeting 64 bit Windows, fixes for buffer overruns and a number of other minor fixes, additions and optimisations. Please see the Changelog files for more detailed information.

Bugs

This release addresses the following security vulnerabilities:

CVE-2009-1720
CVE-2009-1721
CVE-2009-1722

Detailed Changes:

Added support for targetting builds on 64bit Windows and minimising number of compiler warnings on Windows. Thanks to Ger Hobbelt for his contributions to CreateDLL. (Ji Hun Yu)
Added new atttribute types (Florian Kainz):
- M33dAttribute 3x3 double-precision matrix
- M44dAttribute 4x4 double-precision matrix
- V2d 2D double-precision vector
- V3d 3D double-precision vector
Bug fix: crash when reading a damaged image file (found by Apple). An exception thrown inside the PIZ Huffman decoder bypasses initialization of an array of pointers. The uninitialized pointers are later passed to operator delete. (Florian Kainz)
Bug fix: crash when reading a damaged image file (found by Apple). Computing the size of input certain buffers may overflow and wrap around to a small number, later causing writes beyond the end of the buffer. (Florian Kainz)
In the “Technical Introduction” document, added Premultiplied vs. Un-Premulitiplied Color section: states explicitly that pixels with zero alpha and non-zero RGB are allowed, points out that preserving such a pixel can be a problem in application programs with un-premultiplied internal image representations. (Florian Kainz)
exrenvmap improvements:
- New command line flags set the type of the input image to latitude-longitude map or cube-face map, overriding the envmap attribute in the input file header.
- Cube-face maps can now be assembled from or split into six square sub-images.
- Converting a cube-face map into a new cube-face map with the same face size copies the image instead of resampling it. This avoids blurring when a cube-face map is assembled from or split into sub-images. (Florian Kainz)
Updated standard chromaticities in ImfAcesFile.cpp to match final ACES (Academy Color Encoding Specification) document. (Florian Kainz)
Added worldToCamera and worldToNDC matrices to ImfStandardAttributes.h (Florian Kainz)
Increased the maximum length of attribute and channel names from 31 to 255 characters. For files that do contain names longer than 31 characters, a new LONG_NAMES_FLAG in the fil version number is set. This flag causes older versions of the IlmImf library (1.6.1 and earlier) to reject files with long names. Without the flag, older library versions would mis-interpret files with long names as broken. (Florian Kainz)
Reading luminance/chroma-encoded files via the RGBA interface is faster: buffer padding avoids cache thrashing for certain image sizes, redundant calls to saturation() have been eliminated. (Mike Wall)
Added “hemispherical blur” option to exrenvmap. (Florian Kainz)
Added experimental version of I/O classes for ACES file format (restricted OpenEXR format with special primaries and white point); added exr2aces file converter. (Florian Kainz)
Added new constructors to classes Imf::RgbaInputFile and Imf::TiledRgbaInputFile. The new constructors have a layerName parameter, which allows the caller to specify which layer of a multi-layer or multi-view image will be read. (Florian Kainz)
A number of member functions in classes Imf::Header, Imf::ChannelList and Imf::FrameBuffer have parameters of type "const char *". Added equivalent functions that take “const std::string &” parameters. (Florian Kainz)
Added library support for Weta Digital multi-view images: StringVector attribute type, multiView standard attribute of type StringVector, utility functions related to grouping channels into separate views. (Peter Hillman, Florian Kainz)

Version 1.6.1 (October 22, 2007)

This release fixes a buffer overrun in OpenEXR and a Windows build problem in CTL, and it removes a few unnecessary files from the .tar.gz packages.

Detailed Changes:

Removed Windows .suo files from distribution. (Eric Wimmer)
Bug fix: crashes, memory leaks and file descriptor leaks when reading damaged image files (some reported by Apple, others found by running IlmImfFuzzTest). (Florian Kainz)
Added new IlmImfFuzzTest program to test how resilient the IlmImf library is with respect broken input files: the program first damages OpenEXR files by partially overwriting them with random data; then it tries to read the damaged files. If all goes well, the program doesn’t crash. (Florian Kainz)

Version 1.6.0 (August 3, 2007)

OpenEXR 1.6.0:

Reduced generational loss in B44- and B44A-compressed images.
Added B44A compression. This is a variation of B44, but with a better compression ratio for images with large uniform areas, such as in an alpha channel.
Bug fixes.

CTL 1.4.0:

Added new functions to the CTL standard library: 3x3 matrix support, 1D lookup tables with cubic interpolation.
Added new “ctlversion” statement to the language.
Bug fixes.

OpenEXR_CTL 1.0.0:

Applying CTL transforms to a frame buffer is multi-threaded. Bug fixes.

OpenEXR_Viewers 1.0.0:

Implemented new naming conventions for CTL parameters.

IlmBase 1.0.0:

Half now implements “round to nearest even” mode.

Detailed Changes:

Bumped DSO version number to 6.0 (Florian Kainz)
Added new standard attributes related to color rendering with CTL (Color Transformation Language): renderingTransform, lookModTransform and adoptedNeutral. (Florian Kainz)
Bug fix: for pixels with luminance near HALF_MIN, conversion from RGB to luminance/chroma produces NaNs and infinities (Florian Kainz)
Bug fix: excessive desaturation of small details with certain colors after repeatedly loading and saving luminance/chroma encoded images with B44 compression. (Florian Kainz)
Added B44A compression, a minor variation of B44: in most cases, the compression ratio is 2.28:1, the same as with B44, but in uniform image areas where all pixels have the same value, the compression ratio increases to 10.66:1. Uniform areas occur, for example, in an image’s alpha channel, which typically contains large patches that are solid black or white, or in computer- generated images with a black background. (Florian Kainz)
Added flag to configure.ac to enable or disable use of large auto arrays in the IlmImf library. Default is “enable” for Linux, “disable” for everything else. (Darby Johnston, Florian Kainz)
corrected version number on dso’s (libtool) - now 5.0
Separated ILMBASE_LDFLAGS and ILMBASE_LIBS so that test programs can link with static libraries properly
eliminated some warning messages during install (Andrew Kunz)

Version 1.5.0 (December 15, 2006)

The new version includes several significant changes:

OpenEXR supports a new image compression method, called B44. It has a fixed compression rate of 2.28:1, or 4.57:1 if used in combination with luminance/chroma encoding. B44-compressed images can be uncompressed fast enough to support real-time playback of image sequences.
The new playexr program plays back moving image sequences. Playexr is multi-threaded and utilizes the threading capabilities of the IlmImf library that were introduced in OpenEXR 1.3.0. The program plays back B44-compressed images with fairly high-resolution in real time on commodity hardware.
The playexr program and a new version of the existing exrdisplay image viewer both support color rendering via color transforms written in the new Color Transformation Language or CTL. CTL is not part of OpenEXR; it will be released separately. CTL support in playexr and exrdisplay is optional; the programs can be built and will run without CTL.
In preparation for the release of CTL, OpenEXR has been split into three separate packages:
- IlmBase 0.9.0 includes the Half, Iex, Imath and IlmThread libraries
- OpenEXR 1.5.0 includes the IlmImf library, programming examples and utility programs such as exrheader or exrenvmap
- OpenEXRViewers 0.9.0 includes the playexr and exrdisplay programs
The “Technical Introduction to OpenEXR” document now includes a recommendation for storing CIE XYZ pixel data in OpenEXR files.
A new “OpenEXR Image Viewing Software” document describes the playexr and exrdisplay programs. It briefly explains real-time playback and color rendering, and includes recommendations for testing if other image viewing software displays OpenEXR images correctly.
The OpenEXR sample image set now includes B44-compressed files and files with CIE XYZ pixel data.

Detailed Changes:

reorganized packaging of OpenEXR libraries to facilitate integration with CTL. Now this library depends on the library IlmBase. Some functionality has been moved into OpenEXR_Viewers, which depends on two other libraries, CTL and OpenEXR_CTL. Note: previously there were separate releases of OpenEXR-related plugins for Renderman, Shake and Photoshop. OpenEXR is supported natively by Rendermand and Photoshop, so these plugins will not be supported for this or future versions of OpenEXR. (Andrew Kunz)
New build scripts for Linux/Unix (Andrew Kunz)
New Windows project files and build scripts (Kimball Thurston)
float-to-half conversion now preserves the sign of float zeroes and of floats that are so small that they become half zeroes. (Florian Kainz)
Bug fix: Imath::Frustum::planes() returns incorrect planes if the frustum is orthogonal. (Philip Hubbard)
added new framesPerSecond optional standard attribute (Florian Kainz)
Imath cleanup:
- Rewrote function Imath::Quat::setRotation() to make it numerically more accurate, added confidence tests
- Rewrote function Imath::Quat::slerp() using Don Hatch’s method, which is numerically more accurate, added confidence tests.
- Rewrote functions Imath::closestPoints(), Imath::intersect(), added confidence tests.
- Removed broken function Imath::nearestPointOnTriangle().
- Rewrote Imath::drand48(), Imath::lrand48(), etc. to make them functionally identical with the Unix/Linux versions of drand48(), lrand48() and friends.
- Replaced redundant definitions of Int64 in Imath and IlmImf with a single definition in ImathInt64.h. (Florian Kainz)
exrdisplay: if the file’s and the display’s RGB chromaticities differ, the pixels RGB values are transformed from the file’s to the display’s RGB space. (Florian Kainz)
Added new lossy B44 compression method. HALF channels are compressed with a fixed ratio of 2.28:1. UINT and FLOAT channels are stored verbatim, without compression. (Florian Kainz)

Version 1.4.0a (August 9, 2006)

Fixed the ReleaseDLL targets for Visual Studio 2003. (Barnaby Robson)

Version 1.4.0 (August 2, 2006)

This is the next major production-ready release of OpenEXR and offers full compatibility with our last production release, which was 1.2.2. This version obsoletes versions 1.3.x, which were test versions for 1.4.0. If you have been using 1.3.x, please upgrade to 1.4.0.

Production release.
Bug Fix: calling setFrameBuffer() for every scan line while reading a tiled file through the scan line API returns bad pixel data. (Paul Schneider, Florian Kainz)

Version 1.3.1 (June 14, 2006)

Fixed the ReleaseDLL targets for Visual Studio 2005. (Nick Porcino, Drew Hess)
Fixes/enhancements for createDLL. (Nick Porcino)

Version 1.3.0 (June 8, 2006)

This is a test release. The major new feature in this version is support for multithreaded file I/O. We’ve been testing the threaded code internally at ILM for a few months, and we have not encountered any bugs, but we’d like to get some feedback from others before we release the production version.

Here’s a summary of the changes since version 1.2.2:

Support for multithreaded file reading and writing.
Support for Intel-based OS X systems.
Support for Visual Studio 2005.
Better handling of PLATFORM_ and HAVE_ macros.
Updated documentation.
Bug fixes related to handling of incomplete and damaged files.
Numerous bug fixes and cleanups to the autoconf-based build system.
Removed support for the following configurations that were previously supported. Some of these configurations may happen to continue to function, but we can’t help you if they don’t, largely because we don’t have any way to test them:
- IRIX
- OSF1
- SunOS
- OS X versions prior to 10.3.
- gcc on any platform prior to version 3.3

Detailed Changes:

Removed openexr.spec file, it’s out of date and broken to boot. (Drew Hess)
Support for Visual Studio 2005. (Drew Hess, Nick Porcino)
When compiling against OpenEXR headers on Windows, you no longer need to define any HAVE_ or PLATFORM_ macros in your projects. If you are using any OpenEXR DLLs, however, you must define OPENEXR_DLL in your project’s preprocessor directives. (Drew Hess)
Many fixes to the Windows VC7 build system. (Drew Hess, Nick Porcino)
Support for building universal binaries on OS X 10.4. (Drew Hess, Paul Schneider)
Minor configure.ac fix to accomodate OS X’s automake. (Drew Hess)
Removed CPU-specific optimizations from configure.ac, autoconf’s guess at the CPU type isn’t very useful, anyway. Closes #13429. (Drew Hess)
Fixed quoting for tests in configure.ac. Closes #13428. (Drew Hess)
Use host specification instead of target in configure.ac. Closes #13427. (Drew Hess)
Fix use of AC_ARG_ENABLE in configure.ac. Closes #13426. (Drew Hess)
Removed workaround for OS X istream::read bug. (Drew Hess)
Added pthread support to OpenEXR pkg-config file. (Drew Hess)
Added -no-undefined to LDFLAGS and required libs to LIBADD for library projects with other library dependencies, per Rex Dieter’s patch. (Drew Hess)
HAVE_ macros are now defined in the OpenEXRConfig.h header file instead of via compiler flags. There are a handful of public headers which rely on the value of these macros, and projects including these headers have previously needed to define the same macros and values as used by OpenEXR’s 'configure’, which is bad form. Now ‘configure’ writes these values to the OpenEXRConfig.h header file, which is included by any OpenEXR source files that need these macros. This method of specifying HAVE_ macros guarantees that projects will get the proper settings without needing to add compile- time flags to accomodate OpenEXR. Note that this isn’t implemented properly for Windows yet. (Drew Hess)
Platform cleanups:
- No more support for IRIX or OSF1.
- No more explicit support for SunOS, because we have no way to verify that it’s working. I suspect that newish versions of SunOS will just work out of the box, but let me know if not.
- No more PLATFORM_ macros (vestiges of the ILM internal build system). PLATFORM_DARWIN_PPC is replaced by HAVE_DARWIN. PLATFORM_REDHAT_IA32 (which was only used in IlmImfTest) is replaced by HAVE_LINUX_PROCFS.
- OS X 10.4, which is the minimum version we’re going to support with this version, appears to have support for nrand48 and friends, so no need to use the Imath-supplied version of them anymore. (Drew Hess)
No more PLATFORM_WINDOWS or PLATFORM_WIN32, replace with proper standard Windows macros. (Drew Hess)
Remove support for gcc 2.95, no longer supported. (Drew Hess)
Eliminate HAVE_IOS_BASE macro, OpenEXR now requires support for ios_base. (Drew Hess)
Eliminate HAVE_STL_LIMITS macro, OpenEXR now requires the ISO C++ header. (Drew Hess)
Use double quote-style include dirctives for OpenEXR includes. (Drew Hess)
Added a document that gives an overview of the on-disk layout of OpenEXR files (Florian Kainz)
Added sections on layers and on memory-mapped file input to the documentation. (Florian Kainz)
Bug fix: reading an incomplete file causes a deadlock while waiting on a semaphore. (Florian Kainz)
Updated documentation (ReadingAndWritingImageFiles.sxw) and sample code (IlmImfExamples): Added a section about multi-threading, updated section on thread-safety, changed documentation and sample code to use readTiles()/writeTiles() instead of readTile()/writeTile() where possible, mentioned that environment maps contain redundant pixels, updated section on testing if a file is an OpenEXR file. (Florian Kainz)
Multi-threading bug fixes (exceptions could be thrown multiple times, some operations were not thread safe), updated some comments, added comments, more multithreaded testing. (Florian Kainz)
Added multi-threading support: multiple threads cooperate to read or write a single OpenEXR file. (Wojciech Jarosz)
Added operator== and operator!= to Imath::Frustum. (Andre Mazzone)
Bug fix: Reading a PIZ-compressed file with an invalid Huffman code table caused crashes by indexing off the end of an array. (Florian Kainz)

Version 1.2.2 (March 15, 2005)

This is a relatively minor update to the project, with the following changes:

New build system for Windows; support for DLLs.
Switched documentation from HTML to PDF format.
IlmImf: support for image layers in ChannelList.
IlmImf: added isComplete() method to file classes to check whether a file is complete.
IlmImf: exposed staticInitialize() in ImfHeader.h in order to allow thread-safe library initialization in multithreaded applications.
IlmImf: New “time code” standard attribute.
exrdisplay: support for displaying wrap-around texture map images.
exrmaketiled: can now specify wrap mode.
IlmImf: New “wrapmodes” standard attribute to indicate extrapolation mode for mipmaps and ripmaps.
IlmImf: New “key code” standard attribute to identify motion picture film frames.
Imath: Removed TMatrix classes; these classes are still under development and are too difficult to keep in sync with OpenEXR CVS.

Detailed Changes:

Updated README to remove option for building with Visual C++ 6.0. (Drew Hess)
Some older versions of gcc don’t support a full iomanip implemenation; check for this during configuration. (Drew Hess)
Install PDF versions of documentation, remove old/out-of-date HTML documentation. (Florian Kainz)
Removed vc/vc6 directory; Visual C++ 6.0 is no longer supported. (Drew Hess)
Updated README.win32 with details of new build system. (Florian Kainz, Drew Hess)
New build system for Windows / Visual C++ 7 builds both static libraries and DLLs. (Nick Porcino)
Removed Imath::TMatrix and related classes, which are not used anywhere in OpenEXR. (Florian Kainz)
Added minimal support for “image layers” to class Imf::ChannelList (Florian Kainz)
Added new isComplete() method to InputFile, TiledInputFile etc., that checks if a file is complete or if any pixels are missing (for example, because writing the file was aborted prematurely). (Florian Kainz)
Exposed staticInitialize() function in ImfHeader.h in order to allow thread-safe library initialization in multithreaded programs. (Florian Kainz)
Added a new “time code” attribute (Florian Kainz)
exrmaketiled: when a MIPMAP_LEVELS or RIPMAP_LEVELS image is produced, low-pass filtering takes samples outside the image’s data window. This requires extrapolating the image. The user can now specify how the image is extrapolated horizontally and vertically (image is surrounded by black / outermost row of pixels repeats / entire image repeats / entire image repeats, every other copy is a mirror image). exrdisplay: added option to swap the top and botton half, and the left and right half of an image, so that the image’s four corners end up in the center. This is useful for checking the seams of wrap-around texture map images. IlmImf library: Added new “wrapmodes” standard attribute to indicate the extrapolation mode for MIPMAP_LEVELS and RIPMAP_LEVELS images. (Florian Kainz)
Added a new “key code” attribute to identify motion picture film frames. (Florian Kainz)
Removed #include <Iex.h> from ImfAttribute.h, ImfHeader.h and ImfXdr.h so that including header files such as ImfInputFile.h no longer defines ASSERT and THROW macros, which may conflict with similar macros defined by application programs. (Florian Kainz)
Converted HTML documentation to OpenOffice format to make maintaining the documents easier: api.html -> ReadingAndWritingImageFiles.sxw details.html -> TechnicalIntroduction.sxw (Florian Kainz)

Version 1.2.1 (June 6, 2004)

This is a fairly minor release, mostly just a few tweaks, a few bug fixes, and some new documentation. Here are the most important changes:

reduced memory footprint of exrenvmap and exrmaketiled utilities.
IlmImf: new helper functions to determine whether a file is an OpenEXR file, and whether it’s scanline- or tile-based.
IlmImf: bug fix for PXR24 compression with ySampling != 1.
Better support for gcc 3.4.
Warning cleanups in Visual C++.

Detailed Changes:

exrenvmap and exrmaketiled use slightly less memory (Florian Kainz)
Added functions to IlmImf for quickly testing if a file is an OpenEXR file, and whether the file is scan-line based or tiled. (Florian Kainz)
Added preview image examples to IlmImfExamples. Added description of preview images and environment maps to docs/api.html (Florian Kainz)
Bug fix: PXR24 compression did not work properly for channels with ySampling != 1. (Florian Kainz)
Made template <class T> become template <class S, class T> for the transform(ObjectS, ObjectT) methods. This was done to allow for differing templated objects to be passed in e.g. say a Box<Vec3<S>> and a Matrix44<T>, where S=float and T=double. (Jeff Yost, Arkell Rasiah)
New method Matrix44::setTheMatrix(). Used for assigning a M44f to a M44d. (Jeff Yost, Arkell Rasiah)
Added convenience Color typedefs for half versions of Color3 and Color4. Note the Makefile.am for both Imath and ImathTest have been updated with -I and/or -L pathing to Half. (Max Chen, Arkell Rasiah)
Methods equalWithAbsError() and equalWithRelError() are now declared as const. (Colette Mullenhoff, Arkell Rasiah)
Fixes for gcc34. Mainly typename/template/using/this syntax correctness changes. (Nick Ramussen, Arkell Rasiah)
Added Custom low-level file I/O examples to IlmImfExamples and to the docs/api.html document. (Florian Kainz)
Eliminated most warnings messages when OpenEXR is compiled with Visual C++. The OpenEXR code uses lots of (intentional and unintended) implicit type conversions. By default, Visual C++ warns about almost all of them. Most implicit conversions have been removed from the .h files, so that including them should not generate warnings even at warning level 3. Most .cpp files are now compiled with warning level 1. (Florian Kainz)

Version 1.2.0 (May 11, 2004)

OpenEXR 1.2.0 is now available. This is the first official, production-ready release since OpenEXR 1.0.7. If you have been using the development 1.1 series, please switch to 1.2.0 as soon as possible. We believe that OpenEXR 1.2.0 is ready for use in shipping applications. We have been using it in production at ILM for several months now with no problems. There are quite a few major new features in the 1.2 series as compared to the original 1.0 series:

Support for tiled images, including mipmaps and ripmaps. Note that software based on the 1.0 series cannot read or write tiled images. However, simply by recompiling your software against the 1.2 release, any code that reads scanline images can read tiled images, too.
A new Pxr24 compressor, contributed by Pixar Animation Studios. Values produced by the Pxr24 compressor provide the same range as 32-bit floating-point numbers with slightly less precision, and compress quite a bit better. The Pxr24 compressor stores UINT and HALF channels losslessly, and for these data types performs similarly to the ZIP compressor.
OpenEXR now supports high dynamic-range YCA (luminance/chroma/alpha) images with subsampled chroma channels. These files are supported via the RGBA convenience interface, so that data is presented to the application as RGB(A) but stored in the file as YC(A). OpenEXR also supports Y and YA (black-and-white/black-and-white with alpha) images.
An abstracted file I/O interface, so that you can use OpenEXR with interfaces other than C++’s iostreams.
Several new utilities for manipulating tiled image files.

Detailed Changes:

Production-ready release.
Disable long double warnings on OS X. (Drew Hess)
Add new source files to VC7 IlmImfDll target. (Drew Hess)
Iex: change the way that APPEND_EXC and REPLACE_EXC modify their what() string to work around an issue with Visual C++ 7.1. (Florian Kainz, Nick Porcino)
Bumped OpenEXR version to 1.2 and .so versions to 2.0.0 in preparation for the release. (Drew Hess)
Imath: fixed ImathTMatrix.h to work with gcc 3.4. (Drew Hess)
Another quoting fix in openexr.m4. (Drew Hess)
Quoting fix in acinclude.m4 for automake 1.8. (Brad Hards)
Imath: put inline at beginning of declaration in ImathMatrix.h to fix a warning. (Ken McGaugh)
Imath: made Vec equalWithError () methods const.
Cleaned up compile-time Win32 support. (Florian Kainz)
Bug fix: Reading a particular broken PIZ-compressed file caused crashes by indexing off the end of an array. (Florian Kainz)

Version 1.1.1 (March 27, 2004)

OpenEXR 1.1.1 is now available. This another development release. We expect to release a stable version, 1.2, around the end of April. Version 1.1.1 includes support for PXR24 compression, and for high-dynamic-range luminance/chroma images with subsampled chroma channels. Version 1.1.1 also fixes a bug in the 1.1.0 tiled file format.

Detailed Changes:

Half: operator= and variants now return by reference rather than by value. This brings half into conformance with built-in types. (Drew Hess)
Half: remove copy constructor, let compiler supply its own. This improves performance up to 25% on some expressions using half. (Drew Hess)
configure: don’t try to be fancy with CXXFLAGS, just use what the user supplies or let configure choose a sensible default if CXXFLAGS is not defined.
IlmImf: fixed a bug in reading scanline files on big-endian architectures. (Drew Hess)
exrmaketiled: Added an option to select compression type. (Florian Kainz)
exrenvmap: Added an option to select compression type. (Florian Kainz)
exrdisplay: Added some new command-line options. (Florian Kainz)
IlmImf: Added Pixar’s new “slightly lossy” image compression method. The new method, named PXR24, preserves HALF and UINT data without loss, but FLOAT pixels are converted to a 24-bit representation. PXR24 appears to compress FLOAT depth buffers very well without losing much accuracy. (Loren Carpenter, Florian Kainz)
Changed top-level LICENSE file to allow for other copyright holders for individual files.
IlmImf: TILED FILE FORMAT CHANGE. TiledOutputFile was incorrectly interleaving channels and scanlines before passing pixel data to a compressor. The lossless compressors still work, but lossy compressors do not. Fix the bug by interleaving channels and scanlines in tiled files in the same way as ScanLineOutputFile does. Programs compiled with the new version of IlmImf cannot read tiled images produced with version 1.1.0. (Florian Kainz)
IlmImf: ImfXdr.h fix for 64-bit architectures. (Florian Kainz)
IlmImf: OpenEXR now supports YCA (luminance/chroma/alpha) images with subsampled chroma channels. When an image is written with the RGBA convenience interface, selecting WRITE_YCA instead of WRITE_RGBA causes the library to convert the pixels to YCA format. If WRITE_Y is selected, only luminance is stored in the file (for black and white images). When an image file is read with the RGBA convenience interface, YCA data are automatically converted back to RGBA. (Florian Kainz)
IlmImf: speed up reading tiled files as scan lines. (Florian Kainz)
Half: Fixed subtle bug in Half where signaling float NaNs were being converted to inf in half. (Florian Kainz)
gcc 3.3 compiler warning cleanups. (various)
Imath: ImathEuler.h fixes for gcc 3.4. (Garrick Meeker)

Version 1.1.0 (February 6, 2004)

OpenEXR 1.1.0 is now available. This is a major new release with support for tiled images, multi-resolution files (mip/ripmaps), environment maps, and abstracted file I/O. We’ve also released a new set of images that demonstrate these features, and updated the CodeWarrior project and Photoshop plugins for this release. See the downloads section for the source code and the new images.

Detailed Changes:

Added new targets to Visual C++ .NET 2003 project for exrmaketiled, exrenvmap, exrmakepreview, and exrstdattr. (Drew Hess)
A few assorted Win32 fixes for Imath. (Drew Hess)
GNU autoconf builds now produce versioned libraries. This release is 1:0:0. (Drew Hess)
Fixes for Visual C++ .NET 2003. (Paul Schneider)
Updated Visual C++ zlib project file to zlib 1.2.1. (Drew Hess)
exrdisplay: Fixed fragment shader version. (Drew Hess)
*Test: Fixed some compiler issues. (Drew Hess)
Imath: Handle “restrict” keyword properly. (Drew Hess)
IlmImfExamples: Updated to latest versions of example source code, includes tiling and multi-res images. (Florian Kainz)
exrmakepreview: A new utility to create preview images. (Florian Kainz)
exrenvmap: A new utility to create OpenEXR environment maps. (Florian Kainz)
exrstdattr: A new utility to modify standard attributes. (Florian Kainz)
Updated exrheader to print level rounding mode and preview image size. (Florian Kainz)
Updated exrmaketiled to use level rounding mode. (Florian Kainz)
IlmImf: Changed the orientation of lat-long envmaps to match typical panoramic camera setups. (Florian Kainz)
IlmImf: Fixed a bug where partially-completed files with DECREASING_Y could not be read. (Florian Kainz)
IlmImf: Added support for selectable rounding mode (up/down) when generating multiresolution files. (Florian Kainz)
exrdisplay: Support for tiled images, mip/ripmaps, preview images, and display windows. (Florian Kainz, Drew Hess)
exrmaketiled: A new utility which generates tiled versions of OpenEXR images. (Florian Kainz)
IlmImf: Changed Imf::VERSION to Imf::EXR_VERSION to work around problems with autoconf VERSION macro conflict. (Drew Hess)
exrheader: Support for tiles, mipmaps, environment maps. (Florian Kainz)
IlmImf: Environment map support. (Florian Kainz)
IlmImf: Abstracted stream I/O support. (Florian Kainz)
IlmImf: Support for tiled and mip/ripmapped files; requires new file format. (Wojciech Jarosz, Florian Kainz)
Imath: TMatrix, generic 2D matricies and algorithms. (Francesco Callari)
Imath: major quaternions cleanup. (Cary Phillips)
Imath: added GLBegin, GLPushAttrib, GLPushMatrix objects for automatic cleanup on exceptions. (Cary Phillips)
Imath: removed implicit scalar->vector promotions and vector comparisons. (Nick Rasmussen)

Version 1.0.7 (January 7, 2004)

OpenEXR 1.0.7 is now available. In addition to some bug fixes, this version adds support for some new standard attributes, such as primary and white point chromaticities, lens aperture, film speed, image acquisition time and place, and more. If you want to use these new attributes in your applications, see the ImfStandardAttributes.h header file for documentation.

Our project hosting site, Savannah, is still recovering from a compromise last month, so in the meantime, we’re hosting file downloads here. Some of the files are not currently available, but we’re working to restore them.

Detailed Changes:

Fixed a typo in one of the IlmImfTest tests. (Paul Schneider)
Fixed a bug in exrdisplay that causes the image to display as all black if there’s a NaN or infinity in an OpenEXR image. (Florian Kainz)
Updated exrheader per recent changes to IlmImf library. (Florian Kainz)
Changed an errant float to a T in ImathFrame.h nextFrame(). (Cary Phillips)
Support for new “optional standard” attributes (chromaticities, luminance, comments, etc.). (Florian Kainz, Greg Ward, Joseph Goldstone)
Fixed a buffer overrun in ImfOpaqueAttribute. (Paul Schneider)
Added new function, isImfMagic (). (Florian Kainz)

Version 1.0.6:

Added README.win32 to disted files.
Fixed OpenEXR.pc.in pkg-config file, OpenEXR now works with pkg-config.
Random fixes to readme files for new release.
Fixed openexr.m4, now looks in /usr by default.
Added Visual Studio .NET 2003 “solution.”
Fixes for Visual Studio .NET 2003 w/ Microsoft C++ compiler. (Various)
Random Imath fixes and enhancements. Note that extractSHRT now takes an additional optional argument, see ImathMatrixAlgo.h for details. (Various)
Added Wojciech Jarosz to AUTHORS file.
Added test cases for uncompressed case, preview images, frame buffer type conversion. (Wojciech Jarosz, Florian Kainz)
Fix a bug in IlmImf where uncompressed data doesn’t get read/written correctly. (Wojciech Jarosz)
Added support for preview images and preview image attributes (thumbnail images) in IlmImf. (Florian Kainz)
Added support for automatic frame buffer type conversion in IlmImf. (Florian Kainz)
Cleaned up some compile-time checks.
Added HalfTest unit tests.
[exrdisplay] Download half framebuffer to texture memory instead of converting to float first. Requires latest Nvidia drivers.

Version 1.0.5 (April 3, 2003)

Industrial Light & Magic has released the source code for an OpenEXR display driver for Pixar’s Renderman. This display driver is covered under the OpenEXR free software license. See the downloads section for the source code.

Detailed Changes:

Fixed IlmImf.dll to use static runtime libs (Andreas).
Added exrheader project to Visual Studio 6.0 workspace.
Added some example code showing how to use the IlmImf library. (Florian)
Use DLL runtime libs for Win32 libraries rather than static runtime libs.
Add an exrdisplay_fragshader project to the Visual Studio 6.0 workspace to enable fragment shaders in Win32.
Add an IlmImfDll project to the Visual Studio 6.0 workspace.
In Win32, export the ImfCRgbaFile C interface via a DLL so that Visual C++ 6.0 users can link against an Intel-compiled IlmImf. (Andreas Kahler)
Use auto_ptr in ImfAutoArray on Win32, it doesn’t like large automatic stacks.
Performance improvements in PIZ decoding, between 20 and 60% speedup on Athlon and Pentium 4 systems. (Florian)
Updated the README with various information, made some cosmetic changes for readability.
Added fragment shader support to exrdisplay.
Bumped the version to 1.0.5 in prep for release.
Updated README and README.OSX to talk about CodeWarrior project files.
Incorporated Rodrigo Damazio’s patch for an openexr.m4 macro file and an openexr.spec file for building RPMs.
Small change in ImfAttribute.h to make IlmImf compile with gcc 2.95.
Updated ImfDoubleAttribute.h for Codewarrior on MacOS.
Added exrheader utility.
Update to AUTHORS file.
Added a README.win32 file.
Added project files for Visual Studio 6.0.
Initial Win32 port. Requires Visual Studio 6.0 and Intel C++ compiler version 7.0.
Added new intersectT method in ImathSphere.h
Fixed some bugs in ImathQuat.h
Proper use of fltk-config to get platform-specific FLTK compile- and link-time flags.
exrdisplay uses Imath::Math::pow instead of powf now. powf is not availble on all platforms.
Roll OS X “hack” into the source until Apple fixes their istream implementation.

Version 1.0.4****Detailed Changes:

OpenEXR is now covered by a modified BSD license. See LICENSE for the new terms.

Version 1.0.3:****Detailed Changes:

OpenEXR is now in sf.net CVS.
Imf::Xdr namespace cleanups.
Some IlmImfTest cleanups for OS X.
Use .cpp extension in exrdisplay sources.
Iex cleanups.
Make IlmImf compile with Metrowerks Codewarrior.
Change large automatic stacks in ImfHuf.C to auto_ptrs allocated off the heap. MacOS X default stack size isn’t large enough.
std::ios fix for MacOS X in ImfInputFile.C.
Added new FP predecessor/successor functions to Imath, added tests to ImathTest
Fixed a bug in Imath::extractSHRT for 3x3 matricies when exactly one of the original scaling factors is negative, updated ImathTest to check this case.
Install include files when ‘make install’ is run.
exrdisplay requires fltk 1.1+ now in an effort to support a MacOS X display program (fltk 1.1 runs on OS X), though this is untested.
renamed configure.in to configure.ac
Removed some tests from IexTest that are no longer used.
Removed ImfHalfXdr.h, it’s not used anymore.
Revamped the autoconf system, added some compile-time optimizations, a pkgconfig target, and some maintainer-specific stuff.

Version 1.0.2****Detailed Changes:

More OS X fixes in Imath, IlmImf and IlmImfTest.
Imath updates.
Fixed a rotation bug in Imath

Version 1.0.1****Detailed Changes:

Used autoconf 2.53 and automake 1.6 to generate build environment.
Makefile.am cleanups.
OS X fixes.
removed images directory (now distributed separately).

first official release.
added some high-level documentation, removed the old OpenEXR.html documentation.
fixed a few nagging build problems.
bumped IMV_VERSION_NUMBER to 2
