1Version 1.7.1: 2 * Updated the .so verison to 7. 3 (Piotr Stanczyk) 4 5Version 1.7.0: 6 * Added support for targetting builds on 64bit Windows and minimising 7 number of compiler warnings on Windows. Thanks to Ger Hobbelt for his 8 contributions to CreateDLL. 9 (Ji Hun Yu) 10 * Added new atttribute types: 11 M33dAttribute 3x3 double-precision matrix 12 M44dAttribute 4x4 double-precision matrix 13 V2d 2D double-precision vector 14 V3d 3D double-precision vector 15 (Florian Kainz) 16 * Bug fix: crash when reading a damaged image file (found 17 by Apple). An exception thrown inside the PIZ Huffman 18 decoder bypasses initialization of an array of pointers. 19 The uninitialized pointers are later passed to operator 20 delete. 21 (Florian Kainz) 22 * Bug fix: crash when reading a damaged image file (found by 23 Apple). Computing the size of input certain buffers may 24 overflow and wrap around to a small number, later causing 25 writes beyond the end of the buffer. 26 (Florian Kainz) 27 * In the "Technical Introduction" document, added 28 Premultiplied vs. Un-Premulitiplied Color section: 29 states explicitly that pixels with zero alpha and non-zero 30 RGB are allowed, points out that preserving such a pixel can 31 be a problem in application programs with un-premultiplied 32 internal image representations. 33 (Florian Kainz) 34 * exrenvmap improvements: 35 - New command line flags set the type of the input image to 36 latitude-longitude map or cube-face map, overriding the 37 envmap attribute in the input file header. 38 - Cube-face maps can now be assembled from or split into six 39 square sub-images. 40 - Converting a cube-face map into a new cube-face map with 41 the same face size copies the image instead of resampling 42 it. This avoids blurring when a cube-face map is assembled 43 from or split into sub-images. 44 (Florian Kainz) 45 * Updated standard chromaticities in ImfAcesFile.cpp to match 46 final ACES (Academy Color Encoding Specification) document. 47 (Florian Kainz) 48 * Added worldToCamera and worldToNDC matrices to 49 ImfStandardAttributes.h (Florian Kainz) 50 * Increased the maximum length of attribute and channel names 51 from 31 to 255 characters. For files that do contain names 52 longer than 31 characters, a new LONG_NAMES_FLAG in the fil 53 version number is set. This flag causes older versions of 54 the IlmImf library (1.6.1 and earlier) to reject files with 55 long names. Without the flag, older library versions would 56 mis-interpret files with long names as broken. 57 (Florian Kainz) 58 * Reading luminance/chroma-encoded files via the RGBA 59 interface is faster: buffer padding avoids cache thrashing 60 for certain image sizes, redundant calls to saturation() 61 have been eliminated. 62 (Mike Wall) 63 * Added "hemispherical blur" option to exrenvmap. 64 (Florian Kainz) 65 * Added experimental version of I/O classes for ACES file 66 format (restricted OpenEXR format with special primaries 67 and white point); added exr2aces file converter. 68 (Florian Kainz) 69 * Added new constructors to classes Imf::RgbaInputFile and 70 Imf::TiledRgbaInputFile. The new constructors have a 71 layerName parameter, which allows the caller to specify 72 which layer of a multi-layer or multi-view image will 73 be read. 74 (Florian Kainz) 75 * A number of member functions in classes Imf::Header, 76 Imf::ChannelList and Imf::FrameBuffer have parameters 77 of type "const char *". Added equivalent functions that 78 take "const std::string &" parameters. 79 (Florian Kainz) 80 * Added library support for Weta Digital multi-view images: 81 StringVector attribute type, multiView standard attribute 82 of type StringVector, utility functions related to grouping 83 channels into separate views. 84 (Peter Hillman, Florian Kainz) 85 86Version 1.6.1: 87 * Removed Windows .suo files from distribution. 88 (Eric Wimmer) 89 * Bug fix: crashes, memory leaks and file descriptor leaks 90 when reading damaged image files (some reported by Apple, 91 others found by running IlmImfFuzzTest). 92 (Florian Kainz) 93 * Added new IlmImfFuzzTest program to test how resilient the 94 IlmImf library is with respect broken input files: the program 95 first damages OpenEXR files by partially overwriting them with 96 random data; then it tries to read the damaged files. If all 97 goes well, the program doesn't crash. 98 (Florian Kainz) 99 100Version 1.6.0: 101 * Bumped DSO version number to 6.0 102 (Florian Kainz) 103 * Added new standard attributes related to color rendering with 104 CTL (Color Transformation Language): renderingTransform, 105 lookModTransform and adoptedNeutral. 106 (Florian Kainz) 107 * Bug fix: for pixels with luminance near HALF_MIN, conversion 108 from RGB to luminance/chroma produces NaNs and infinities 109 (Florian Kainz) 110 * Bug fix: excessive desaturation of small details with certain 111 colors after repeatedly loading and saving luminance/chroma 112 encoded images with B44 compression. 113 (Florian Kainz) 114 * Added B44A compression, a minor variation of B44: in most cases, 115 the compression ratio is 2.28:1, the same as with B44, but in 116 uniform image areas where all pixels have the same value, the 117 compression ratio increases to 10.66:1. Uniform areas occur, for 118 example, in an image's alpha channel, which typically contains 119 large patches that are solid black or white, or in computer- 120 generated images with a black background. 121 (Florian Kainz) 122 * Added flag to configure.ac to enable or disable use of large 123 auto arrays in the IlmImf library. Default is "enable" for 124 Linux, "disable" for everything else. 125 (Darby Johnston, Florian Kainz) 126 * corrected version number on dso's (libtool) - now 5.0 127 * Separated ILMBASE_LDFLAGS and ILMBASE_LIBS so that test programs 128 can link with static libraries properly 129 * eliminated some warning messages during install 130 (Andrew Kunz) 131 132Version 1.5.0: 133 * reorganized packaging of OpenEXR libraries to facilitate 134 integration with CTL. Now this library depends on the library 135 IlmBase. Some functionality has been moved into OpenEXR_Viewers, 136 which depends on two other libraries, CTL and OpenEXR_CTL. 137 Note: previously there were separate releases of 138 OpenEXR-related plugins for Renderman, Shake and Photoshop. 139 OpenEXR is supported natively by Rendermand and Photoshop, so 140 these plugins will not be supported for this or future 141 versions of OpenEXR. 142 (Andrew Kunz) 143 * New build scripts for Linux/Unix 144 (Andrew Kunz) 145 * New Windows project files and build scripts 146 (Kimball Thurston) 147 * float-to-half conversion now preserves the sign of float zeroes 148 and of floats that are so small that they become half zeroes. 149 (Florian Kainz) 150 * Bug fix: Imath::Frustum<T>::planes() returns incorrect planes 151 if the frustum is orthogonal. 152 (Philip Hubbard) 153 * added new framesPerSecond optional standard attribute 154 (Florian Kainz) 155 * Imath cleanup: 156 - Rewrote function Imath::Quat<T>::setRotation() to make it 157 numerically more accurate, added confidence tests 158 - Rewrote function Imath::Quat<T>::slerp() using Don Hatch's 159 method, which is numerically more accurate, added confidence 160 tests. 161 - Rewrote functions Imath::closestPoints(), Imath::intersect(), 162 added confidence tests. 163 - Removed broken function Imath::nearestPointOnTriangle(). 164 - Rewrote Imath::drand48(), Imath::lrand48(), etc. to make 165 them functionally identical with the Unix/Linux versions 166 of drand48(), lrand48() and friends. 167 - Replaced redundant definitions of Int64 in Imath and IlmImf 168 with a single definition in ImathInt64.h. 169 (Florian Kainz) 170 * exrdisplay: if the file's and the display's RGB chromaticities 171 differ, the pixels RGB values are transformed from the file's 172 to the display's RGB space. 173 (Florian Kainz) 174 * Added new lossy B44 compression method. HALF channels are 175 compressed with a fixed ratio of 2.28:1. UINT and FLOAT 176 channels are stored verbatim, without compression. 177 (Florian Kainz) 178 179Version 1.4.0a: 180 * Fixed the ReleaseDLL targets for Visual Studio 2003. 181 (Barnaby Robson) 182 183Version 1.4.0: 184 * Production release. 185 * Bug Fix: calling setFrameBuffer() for every scan line 186 while reading a tiled file through the scan line API 187 returns bad pixel data. (Paul Schneider, Florian Kainz) 188 189Version 1.3.1: 190 * Fixed the ReleaseDLL targets for Visual Studio 2005. 191 (Nick Porcino, Drew Hess) 192 * Fixes/enhancements for createDLL. 193 (Nick Porcino) 194 195Version 1.3.0: 196 * Removed openexr.spec file, it's out of date and broken to 197 boot. 198 (Drew Hess) 199 * Support for Visual Studio 2005. 200 (Drew Hess, Nick Porcino) 201 * When compiling against OpenEXR headers on Windows, you 202 no longer need to define any HAVE_* or PLATFORM_* 203 macros in your projects. If you are using any OpenEXR 204 DLLs, however, you must define OPENEXR_DLL in your 205 project's preprocessor directives. 206 (Drew Hess) 207 * Many fixes to the Windows VC7 build system. 208 (Drew Hess, Nick Porcino) 209 * Support for building universal binaries on OS X 10.4. 210 (Drew Hess, Paul Schneider) 211 * Minor configure.ac fix to accomodate OS X's automake. 212 (Drew Hess) 213 * Removed CPU-specific optimizations from configure.ac, 214 autoconf's guess at the CPU type isn't very useful, 215 anyway. Closes #13429. 216 (Drew Hess) 217 * Fixed quoting for tests in configure.ac. Closes #13428. 218 (Drew Hess) 219 * Use host specification instead of target in configure.ac. 220 Closes #13427. 221 (Drew Hess) 222 * Fix use of AC_ARG_ENABLE in configure.ac. Closes 223 #13426. 224 (Drew Hess) 225 * Removed workaround for OS X istream::read bug. 226 (Drew Hess) 227 * Added pthread support to OpenEXR pkg-config file. 228 (Drew Hess) 229 * Added -no-undefined to LDFLAGS and required libs to LIBADD 230 for library projects with other library dependencies, per 231 Rex Dieter's patch. 232 (Drew Hess) 233 * HAVE_* macros are now defined in the OpenEXRConfig.h header 234 file instead of via compiler flags. There are a handful of 235 public headers which rely on the value of these macros, 236 and projects including these headers have previously needed 237 to define the same macros and values as used by OpenEXR's 238 'configure', which is bad form. Now 'configure' writes these 239 values to the OpenEXRConfig.h header file, which is included 240 by any OpenEXR source files that need these macros. This 241 method of specifying HAVE_* macros guarantees that projects 242 will get the proper settings without needing to add compile- 243 time flags to accomodate OpenEXR. Note that this isn't 244 implemented properly for Windows yet. 245 (Drew Hess) 246 * Platform cleanups: 247 - No more support for IRIX or OSF1. 248 - No more explicit support for SunOS, because we have no way to 249 verify that it's working. I suspect that newish versions of 250 SunOS will just work out of the box, but let me know if not. 251 - No more PLATFORM_* macros (vestiges of the ILM internal build 252 system). PLATFORM_DARWIN_PPC is replaced by HAVE_DARWIN. 253 PLATFORM_REDHAT_IA32 (which was only used in IlmImfTest) is 254 replaced by HAVE_LINUX_PROCFS. 255 - OS X 10.4, which is the minimum version we're going to support 256 with this version, appears to have support for nrand48 and friends, 257 so no need to use the Imath-supplied version of them anymore. 258 (Drew Hess) 259 * No more PLATFORM_WINDOWS or PLATFORM_WIN32, replace with 260 proper standard Windows macros. (Drew Hess) 261 * Remove support for gcc 2.95, no longer supported. (Drew Hess) 262 * Eliminate HAVE_IOS_BASE macro, OpenEXR now requires support for 263 ios_base. (Drew Hess) 264 * Eliminate HAVE_STL_LIMITS macro, OpenEXR now requires the ISO C++ 265 <limits> header. (Drew Hess) 266 * Use double quote-style include dirctives for OpenEXR 267 includes. (Drew Hess) 268 * Added a document that gives an overview of the on-disk 269 layout of OpenEXR files (Florian Kainz) 270 * Added sections on layers and on memory-mapped file input 271 to the documentation. (Florian Kainz) 272 * Bug fix: reading an incomplete file causes a deadlock while 273 waiting on a semaphore. (Florian Kainz) 274 * Updated documentation (ReadingAndWritingImageFiles.sxw) and 275 sample code (IlmImfExamples): 276 Added a section about multi-threading, updated section on 277 thread-safety, changed documentation and sample code to use 278 readTiles()/writeTiles() instead of readTile()/writeTile() 279 where possible, mentioned that environment maps contain 280 redundant pixels, updated section on testing if a file is 281 an OpenEXR file. 282 (Florian Kainz) 283 * Multi-threading bug fixes (exceptions could be thrown 284 multiple times, some operations were not thread safe), 285 updated some comments, added comments, more multithreaded 286 testing. 287 (Florian Kainz) 288 * Added multi-threading support: multiple threads 289 cooperate to read or write a single OpenEXR file. 290 (Wojciech Jarosz) 291 * Added operator== and operator!= to Imath::Frustum. 292 (Andre Mazzone) 293 * Bug fix: Reading a PIZ-compressed file with an invalid 294 Huffman code table caused crashes by indexing off the 295 end of an array. 296 (Florian Kainz) 297 298Version 1.2.2: 299 * Updated README to remove option for building with Visual C++ 6.0. 300 (Drew Hess) 301 * Some older versions of gcc don't support a full iomanip 302 implemenation; check for this during configuration. 303 (Drew Hess) 304 * Install PDF versions of documentation, remove old/out-of-date 305 HTML documentation. (Florian Kainz) 306 * Removed vc/vc6 directory; Visual C++ 6.0 is no longer 307 supported. (Drew Hess) 308 * Updated README.win32 with details of new build system. 309 (Florian Kainz, Drew Hess) 310 * New build system for Windows / Visual C++ 7 builds both 311 static libraries and DLLs. 312 (Nick Porcino) 313 * Removed Imath::TMatrix<T> and related classes, which are not 314 used anywhere in OpenEXR. 315 (Florian Kainz) 316 * Added minimal support for "image layers" to class Imf::ChannelList 317 (Florian Kainz) 318 * Added new isComplete() method to InputFile, TiledInputFile 319 etc., that checks if a file is complete or if any pixels 320 are missing (for example, because writing the file was 321 aborted prematurely). 322 (Florian Kainz) 323 * Exposed staticInitialize() function in ImfHeader.h in order 324 to allow thread-safe library initialization in multithreaded 325 programs. 326 (Florian Kainz) 327 * Added a new "time code" attribute 328 (Florian Kainz) 329 * exrmaketiled: when a MIPMAP_LEVELS or RIPMAP_LEVELS image 330 is produced, low-pass filtering takes samples outside the 331 image's data window. This requires extrapolating the image. 332 The user can now specify how the image is extrapolated 333 horizontally and vertically (image is surrounded by black / 334 outermost row of pixels repeats / entire image repeats / 335 entire image repeats, every other copy is a mirror image). 336 exrdisplay: added option to swap the top and botton half, 337 and the left and right half of an image, so that the image's 338 four corners end up in the center. This is useful for checking 339 the seams of wrap-around texture map images. 340 IlmImf library: Added new "wrapmodes" standard attribute 341 to indicate the extrapolation mode for MIPMAP_LEVELS and 342 RIPMAP_LEVELS images. 343 (Florian Kainz) 344 * Added a new "key code" attribute to identify motion picture 345 film frames. 346 (Florian Kainz) 347 * Removed #include <Iex.h> from ImfAttribute.h, ImfHeader.h 348 and ImfXdr.h so that including header files such as 349 ImfInputFile.h no longer defines ASSERT and THROW macros, 350 which may conflict with similar macros defined by 351 application programs. 352 (Florian Kainz) 353 * Converted HTML documentation to OpenOffice format to 354 make maintaining the documents easier: 355 api.html -> ReadingAndWritingImageFiles.sxw 356 details.html -> TechnicalIntroduction.sxw 357 (Florian Kainz) 358 359Version 1.2.1: 360 * exrenvmap and exrmaketiled use slightly less memory 361 (Florian Kainz) 362 * Added functions to IlmImf for quickly testing if a file 363 is an OpenEXR file, and whether the file is scan-line 364 based or tiled. (Florian Kainz) 365 * Added preview image examples to IlmImfExamples. Added 366 description of preview images and environment maps to 367 docs/api.html (Florian Kainz) 368 * Bug fix: PXR24 compression did not work properly for channels 369 with ySampling != 1. 370 (Florian Kainz) 371 * Made template <class T> become template <class S, class T> for 372 the transform(ObjectS, ObjectT) methods. This was done to allow 373 for differing templated objects to be passed in e.g. say a 374 Box<Vec3<S>> and a Matrix44<T>, where S=float and T=double. 375 (Jeff Yost, Arkell Rasiah) 376 * New method Matrix44::setTheMatrix(). Used for assigning a 377 M44f to a M44d. (Jeff Yost, Arkell Rasiah) 378 * Added convenience Color typedefs for half versions of Color3 379 and Color4. Note the Makefile.am for both Imath and ImathTest 380 have been updated with -I and/or -L pathing to Half. 381 (Max Chen, Arkell Rasiah) 382 * Methods equalWithAbsError() and equalWithRelError() are now 383 declared as const. (Colette Mullenhoff, Arkell Rasiah) 384 * Fixes for gcc34. Mainly typename/template/using/this syntax 385 correctness changes. (Nick Ramussen, Arkell Rasiah) 386 * Added Custom low-level file I/O examples to IlmImfExamples 387 and to the docs/api.html document. (Florian Kainz) 388 * Eliminated most warnings messages when OpenEXR is compiled 389 with Visual C++. The OpenEXR code uses lots of (intentional 390 and unintended) implicit type conversions. By default, Visual 391 C++ warns about almost all of them. Most implicit conversions 392 have been removed from the .h files, so that including them 393 should not generate warnings even at warning level 3. Most 394 .cpp files are now compiled with warning level 1. 395 (Florian Kainz) 396 397Version 1.2.0: 398 * Production-ready release. 399 * Disable long double warnings on OS X. (Drew Hess) 400 * Add new source files to VC7 IlmImfDll target. (Drew Hess) 401 * Iex: change the way that APPEND_EXC and REPLACE_EXC modify 402 their what() string to work around an issue with Visual C++ 403 7.1. (Florian Kainz, Nick Porcino) 404 * Bumped OpenEXR version to 1.2 and .so versions to 2.0.0 in 405 preparation for the release. (Drew Hess) 406 * Imath: fixed ImathTMatrix.h to work with gcc 3.4. (Drew Hess) 407 * Another quoting fix in openexr.m4. (Drew Hess) 408 * Quoting fix in acinclude.m4 for automake 1.8. (Brad Hards) 409 * Imath: put inline at beginning of declaration in ImathMatrix.h 410 to fix a warning. (Ken McGaugh) 411 * Imath: made Vec equalWith*Error () methods const. 412 * Cleaned up compile-time Win32 support. (Florian Kainz) 413 * Bug fix: Reading a particular broken PIZ-compressed file 414 caused crashes by indexing off the end of an array. 415 (Florian Kainz) 416 417Version 1.1.1: 418 * Half: operator= and variants now return by reference rather 419 than by value. This brings half into conformance with 420 built-in types. (Drew Hess) 421 * Half: remove copy constructor, let compiler supply its 422 own. This improves performance up to 25% on some 423 expressions using half. (Drew Hess) 424 * configure: don't try to be fancy with CXXFLAGS, just use 425 what the user supplies or let configure choose a sensible 426 default if CXXFLAGS is not defined. 427 * IlmImf: fixed a bug in reading scanline files on big-endian 428 architectures. (Drew Hess) 429 * exrmaketiled: Added an option to select compression type. 430 (Florian Kainz) 431 * exrenvmap: Added an option to select compression type. 432 (Florian Kainz) 433 * exrdisplay: Added some new command-line options. (Florian Kainz) 434 * IlmImf: Added Pixar's new "slightly lossy" image compression 435 method. The new method, named PXR24, preserves HALF and 436 UINT data without loss, but FLOAT pixels are converted to 437 a 24-bit representation. PXR24 appears to compress 438 FLOAT depth buffers very well without losing much accuracy. 439 (Loren Carpenter, Florian Kainz) 440 * Changed top-level LICENSE file to allow for other copyright 441 holders for individual files. 442 * IlmImf: TILED FILE FORMAT CHANGE. TiledOutputFile was 443 incorrectly interleaving channels and scanlines before 444 passing pixel data to a compressor. The lossless compressors 445 still work, but lossy compressors do not. Fix the bug by 446 interleaving channels and scanlines in tiled files in the 447 same way as ScanLineOutputFile does. Programs compiled with 448 the new version of IlmImf cannot read tiled images produced 449 with version 1.1.0. (Florian Kainz) 450 * IlmImf: ImfXdr.h fix for 64-bit architectures. (Florian Kainz) 451 * IlmImf: OpenEXR now supports YCA (luminance/chroma/alpha) 452 images with subsampled chroma channels. When an image 453 is written with the RGBA convenience interface, selecting 454 WRITE_YCA instead of WRITE_RGBA causes the library to 455 convert the pixels to YCA format. If WRITE_Y is selected, 456 only luminance is stored in the file (for black and white 457 images). When an image file is read with the RGBA convenience 458 interface, YCA data are automatically converted back to RGBA. 459 (Florian Kainz) 460 * IlmImf: speed up reading tiled files as scan lines. 461 (Florian Kainz) 462 * Half: Fixed subtle bug in Half where signaling float NaNs 463 were being converted to inf in half. (Florian Kainz) 464 * gcc 3.3 compiler warning cleanups. (various) 465 * Imath: ImathEuler.h fixes for gcc 3.4. (Garrick Meeker) 466 467Version 1.1.0: 468 * Added new targets to Visual C++ .NET 2003 project 469 for exrmaketiled, exrenvmap, exrmakepreview, and exrstdattr. 470 (Drew Hess) 471 * A few assorted Win32 fixes for Imath. (Drew Hess) 472 * GNU autoconf builds now produce versioned libraries. 473 This release is 1:0:0. (Drew Hess) 474 * Fixes for Visual C++ .NET 2003. (Paul Schneider) 475 * Updated Visual C++ zlib project file to zlib 1.2.1. 476 (Drew Hess) 477 * exrdisplay: Fixed fragment shader version. (Drew Hess) 478 * *Test: Fixed some compiler issues. (Drew Hess) 479 * Imath: Handle "restrict" keyword properly. (Drew Hess) 480 * IlmImfExamples: Updated to latest versions of example 481 source code, includes tiling and multi-res images. 482 (Florian Kainz) 483 * exrmakepreview: A new utility to create preview images. 484 (Florian Kainz) 485 * exrenvmap: A new utility to create OpenEXR environment 486 maps. (Florian Kainz) 487 * exrstdattr: A new utility to modify standard 488 attributes. (Florian Kainz) 489 * Updated exrheader to print level rounding mode and 490 preview image size. (Florian Kainz) 491 * Updated exrmaketiled to use level rounding mode. 492 (Florian Kainz) 493 * IlmImf: Changed the orientation of lat-long envmaps to 494 match typical panoramic camera setups. (Florian Kainz) 495 * IlmImf: Fixed a bug where partially-completed files with 496 DECREASING_Y could not be read. (Florian Kainz) 497 * IlmImf: Added support for selectable rounding mode (up/down) 498 when generating multiresolution files. (Florian Kainz) 499 * exrdisplay: Support for tiled images, mip/ripmaps, preview 500 images, and display windows. (Florian Kainz, Drew Hess) 501 * exrmaketiled: A new utility which generates tiled 502 versions of OpenEXR images. (Florian Kainz) 503 * IlmImf: Changed Imf::VERSION to Imf::EXR_VERSION to 504 work around problems with autoconf VERSION macro 505 conflict. (Drew Hess) 506 * exrheader: Support for tiles, mipmaps, environment 507 maps. (Florian Kainz) 508 * IlmImf: Environment map support. (Florian Kainz) 509 * IlmImf: Abstracted stream I/O support. (Florian Kainz) 510 * IlmImf: Support for tiled and mip/ripmapped files; 511 requires new file format. (Wojciech Jarosz, Florian Kainz) 512 * Imath: TMatrix*, generic 2D matricies and algorithms. 513 (Francesco Callari) 514 * Imath: major quaternions cleanup. (Cary Phillips) 515 * Imath: added GLBegin, GLPushAttrib, GLPushMatrix objects 516 for automatic cleanup on exceptions. (Cary Phillips) 517 * Imath: removed implicit scalar->vector promotions and vector 518 comparisons. (Nick Rasmussen) 519 520Version 1.0.7: 521 * Fixed a typo in one of the IlmImfTest tests. (Paul Schneider) 522 * Fixed a bug in exrdisplay that causes the image to display 523 as all black if there's a NaN or infinity in an OpenEXR 524 image. (Florian Kainz) 525 * Updated exrheader per recent changes to IlmImf library. 526 (Florian Kainz) 527 * Changed an errant float to a T in ImathFrame.h nextFrame(). 528 (Cary Phillips) 529 * Support for new "optional standard" attributes 530 (chromaticities, luminance, comments, etc.). 531 (Florian Kainz, Greg Ward, Joseph Goldstone) 532 * Fixed a buffer overrun in ImfOpaqueAttribute. (Paul Schneider) 533 * Added new function, isImfMagic (). (Florian Kainz) 534 535Version 1.0.6: 536 * Added README.win32 to disted files. 537 * Fixed OpenEXR.pc.in pkg-config file, OpenEXR now works 538 with pkg-config. 539 * Random fixes to readme files for new release. 540 * Fixed openexr.m4, now looks in /usr by default. 541 * Added Visual Studio .NET 2003 "solution." 542 * Fixes for Visual Studio .NET 2003 w/ Microsoft C++ compiler. 543 (Various) 544 * Random Imath fixes and enhancements. Note that 545 extractSHRT now takes an additional optional 546 argument, see ImathMatrixAlgo.h for details. (Various) 547 * Added Wojciech Jarosz to AUTHORS file. 548 * Added test cases for uncompressed case, preview images, 549 frame buffer type conversion. (Wojciech Jarosz, 550 Florian Kainz) 551 * Fix a bug in IlmImf where uncompressed data doesn't get 552 read/written correctly. (Wojciech Jarosz) 553 * Added support for preview images and preview image 554 attributes (thumbnail images) in IlmImf. (Florian Kainz) 555 * Added support for automatic frame buffer type conversion 556 in IlmImf. (Florian Kainz) 557 * Cleaned up some compile-time checks. 558 * Added HalfTest unit tests. 559 * [exrdisplay] Download half framebuffer to texture memory 560 instead of converting to float first. Requires latest 561 Nvidia drivers. 562 563Version 1.0.5: 564 * Fixed IlmImf.dll to use static runtime libs (Andreas). 565 * Added exrheader project to Visual Studio 6.0 workspace. 566 * Added some example code showing how to use the IlmImf library. 567 (Florian) 568 * Use DLL runtime libs for Win32 libraries rather than static 569 runtime libs. 570 * Add an exrdisplay_fragshader project to the Visual Studio 6.0 571 workspace to enable fragment shaders in Win32. 572 * Add an IlmImfDll project to the Visual Studio 6.0 workspace. 573 * In Win32, export the ImfCRgbaFile C interface via a DLL so 574 that Visual C++ 6.0 users can link against an Intel-compiled 575 IlmImf. (Andreas Kahler) 576 * Use auto_ptr in ImfAutoArray on Win32, it doesn't like large 577 automatic stacks. 578 * Performance improvements in PIZ decoding, between 579 20 and 60% speedup on Athlon and Pentium 4 systems. 580 (Florian) 581 * Updated the README with various information, made 582 some cosmetic changes for readability. 583 * Added fragment shader support to exrdisplay. 584 * Bumped the version to 1.0.5 in prep for release. 585 * Updated README and README.OSX to talk about CodeWarrior 586 project files. 587 * Incorporated Rodrigo Damazio's patch for an openexr.m4 588 macro file and an openexr.spec file for building RPMs. 589 * Small change in ImfAttribute.h to make IlmImf compile with gcc 2.95. 590 * Updated ImfDoubleAttribute.h for Codewarrior on MacOS. 591 * Added exrheader utility. 592 * Update to AUTHORS file. 593 * Added a README.win32 file. 594 * Added project files for Visual Studio 6.0. 595 * Initial Win32 port. Requires Visual Studio 6.0 and Intel C++ 596 compiler version 7.0. 597 * Added new intersectT method in ImathSphere.h 598 * Fixed some bugs in ImathQuat.h 599 * Proper use of fltk-config to get platform-specific FLTK 600 compile- and link-time flags. 601 * exrdisplay uses Imath::Math<T>::pow instead of powf now. 602 powf is not availble on all platforms. 603 * Roll OS X "hack" into the source until Apple fixes their 604 istream implementation. 605 606Version 1.0.4: 607 * OpenEXR is now covered by a modified BSD license. See LICENSE 608 for the new terms. 609 610Version 1.0.3: 611 612 * OpenEXR is now in sf.net CVS. 613 * Imf::Xdr namespace cleanups. 614 * Some IlmImfTest cleanups for OS X. 615 * Use .cpp extension in exrdisplay sources. 616 * Iex cleanups. 617 * Make IlmImf compile with Metrowerks Codewarrior. 618 * Change large automatic stacks in ImfHuf.C to auto_ptrs allocated 619 off the heap. MacOS X default stack size isn't large enough. 620 * std::ios fix for MacOS X in ImfInputFile.C. 621 * Added new FP predecessor/successor functions to Imath, added 622 tests to ImathTest 623 * Fixed a bug in Imath::extractSHRT for 3x3 matricies when 624 exactly one of the original scaling factors is negative, updated 625 ImathTest to check this case. 626 * Install include files when 'make install' is run. 627 * exrdisplay requires fltk 1.1+ now in an effort to support 628 a MacOS X display program (fltk 1.1 runs on OS X), though this 629 is untested. 630 * renamed configure.in to configure.ac 631 * Removed some tests from IexTest that are no longer used. 632 * Removed ImfHalfXdr.h, it's not used anymore. 633 * Revamped the autoconf system, added some compile-time 634 optimizations, a pkgconfig target, and some maintainer-specific 635 stuff. 636 637Version 1.0.2: 638 639 * More OS X fixes in Imath, IlmImf and IlmImfTest. 640 * Imath updates. 641 * Fixed a rotation bug in Imath 642 643Version 1.0.1: 644 645 * Used autoconf 2.53 and automake 1.6 to generate build environment. 646 * Makefile.am cleanups. 647 * OS X fixes. 648 * removed images directory (now distributed separately). 649 650Version 1.0: 651 652 * first official release. 653 * added some high-level documentation, removed the old OpenEXR.html 654 documentation. 655 * fixed a few nagging build problems. 656 * bumped IMV_VERSION_NUMBER to 2 657 658Version 0.9: 659 660 * added exrdisplay viewer application. 661 * cleanup _data in Imf::InputFile and Imf::OutputFile constructors. 662 * removed old ILM copyright notices. 663 664Version 0.8: 665 666 * Initial release. 667
