  1. * Added new atttribute types:
  2. M33dAttribute 3x3 double-precision matrix
  3. M44dAttribute 4x4 double-precision matrix
  4. V2d 2D double-precision vector
  5. V3d 3D double-precision vector
  6. (Florian Kainz)
  7. * Bug fix: crash when reading a damaged image file (found
  8. by Apple). An exception thrown inside the PIZ Huffman
  9. decoder bypasses initialization of an array of pointers.
  10. The uninitialized pointers are later passed to operator
  11. delete.
  12. (Florian Kainz)
  13. * Bug fix: crash when reading a damaged image file (found by
  14. Apple). Computing the size of input certain buffers may
  15. overflow and wrap around to a small number, later causing
  16. writes beyond the end of the buffer.
  17. (Florian Kainz)
  18. * In the "Technical Introduction" document, added
  19. Premultiplied vs. Un-Premulitiplied Color section:
  20. states explicitly that pixels with zero alpha and non-zero
  21. RGB are allowed, points out that preserving such a pixel can
  22. be a problem in application programs with un-premultiplied
  23. internal image representations.
  24. (Florian Kainz)
  25. * exrenvmap improvements:
  26. - New command line flags set the type of the input image to
  27. latitude-longitude map or cube-face map, overriding the
  28. envmap attribute in the input file header.
  29. - Cube-face maps can now be assembled from or split into six
  30. square sub-images.
  31. - Converting a cube-face map into a new cube-face map with
  32. the same face size copies the image instead of resampling
  33. it. This avoids blurring when a cube-face map is assembled
  34. from or split into sub-images.
  35. (Florian Kainz)
  36. * Updated standard chromaticities in ImfAcesFile.cpp to match
  37. final ACES (Academy Color Encoding Specification) document.
  38. (Florian Kainz)
  39. * Added worldToCamera and worldToNDC matrices to
  40. ImfStandardAttributes.h (Florian Kainz)
  41. * Increased the maximum length of attribute and channel names
  42. from 31 to 255 characters. For files that do contain names
  43. longer than 31 characters, a new LONG_NAMES_FLAG in the fil
  44. version number is set. This flag causes older versions of
  45. the IlmImf library (1.6.1 and earlier) to reject files with
  46. long names. Without the flag, older library versions would
  47. mis-interpret files with long names as broken.
  48. (Florian Kainz)
  49. * Reading luminance/chroma-encoded files via the RGBA
  50. interface is faster: buffer padding avoids cache thrashing
  51. for certain image sizes, redundant calls to saturation()
  52. have been eliminated.
  53. (Mike Wall)
  54. * Added "hemispherical blur" option to exrenvmap.
  55. (Florian Kainz)
  56. * Added experimental version of I/O classes for ACES file
  57. format (restricted OpenEXR format with special primaries
  58. and white point); added exr2aces file converter.
  59. (Florian Kainz)
  60. * Added new constructors to classes Imf::RgbaInputFile and
  61. Imf::TiledRgbaInputFile. The new constructors have a
  62. layerName parameter, which allows the caller to specify
  63. which layer of a multi-layer or multi-view image will
  64. be read.
  65. (Florian Kainz)
  66. * A number of member functions in classes Imf::Header,
  67. Imf::ChannelList and Imf::FrameBuffer have parameters
  68. of type "const char *". Added equivalent functions that
  69. take "const std::string &" parameters.
  70. (Florian Kainz)
  71. * Added library support for Weta Digital multi-view images:
  72. StringVector attribute type, multiView standard attribute
  73. of type StringVector, utility functions related to grouping
  74. channels into separate views.
  75. (Peter Hillman, Florian Kainz)
  76. Version 1.6.1:
  77. * Removed Windows .suo files from distribution.
  78. (Eric Wimmer)
  79. * Bug fix: crashes, memory leaks and file descriptor leaks
  80. when reading damaged image files (some reported by Apple,
  81. others found by running IlmImfFuzzTest).
  82. (Florian Kainz)
  83. * Added new IlmImfFuzzTest program to test how resilient the
  84. IlmImf library is with respect broken input files: the program
  85. first damages OpenEXR files by partially overwriting them with
  86. random data; then it tries to read the damaged files. If all
  87. goes well, the program doesn't crash.
  88. (Florian Kainz)
  89. Version 1.6.0:
  90. * Bumped DSO version number to 6.0
  91. (Florian Kainz)
  92. * Added new standard attributes related to color rendering with
  93. CTL (Color Transformation Language): renderingTransform,
  94. lookModTransform and adoptedNeutral.
  95. (Florian Kainz)
  96. * Bug fix: for pixels with luminance near HALF_MIN, conversion
  97. from RGB to luminance/chroma produces NaNs and infinities
  98. (Florian Kainz)
  99. * Bug fix: excessive desaturation of small details with certain
  100. colors after repeatedly loading and saving luminance/chroma
  101. encoded images with B44 compression.
  102. (Florian Kainz)
  103. * Added B44A compression, a minor variation of B44: in most cases,
  104. the compression ratio is 2.28:1, the same as with B44, but in
  105. uniform image areas where all pixels have the same value, the
  106. compression ratio increases to 10.66:1. Uniform areas occur, for
  107. example, in an image's alpha channel, which typically contains
  108. large patches that are solid black or white, or in computer-
  109. generated images with a black background.
  110. (Florian Kainz)
  111. * Added flag to configure.ac to enable or disable use of large
  112. auto arrays in the IlmImf library. Default is "enable" for
  113. Linux, "disable" for everything else.
  114. (Darby Johnston, Florian Kainz)
  115. * corrected version number on dso's (libtool) - now 5.0
  116. * Separated ILMBASE_LDFLAGS and ILMBASE_LIBS so that test programs
  117. can link with static libraries properly
  118. * eliminated some warning messages during install
  119. (Andrew Kunz)
  120. Version 1.5.0:
  121. * reorganized packaging of OpenEXR libraries to facilitate
  122. integration with CTL. Now this library depends on the library
  123. IlmBase. Some functionality has been moved into OpenEXR_Viewers,
  124. which depends on two other libraries, CTL and OpenEXR_CTL.
  125. Note: previously there were separate releases of
  126. OpenEXR-related plugins for Renderman, Shake and Photoshop.
  127. OpenEXR is supported natively by Rendermand and Photoshop, so
  128. these plugins will not be supported for this or future
  129. versions of OpenEXR.
  130. (Andrew Kunz)
  131. * New build scripts for Linux/Unix
  132. (Andrew Kunz)
  133. * New Windows project files and build scripts
  134. (Kimball Thurston)
  135. * float-to-half conversion now preserves the sign of float zeroes
  136. and of floats that are so small that they become half zeroes.
  137. (Florian Kainz)
  138. * Bug fix: Imath::Frustum<T>::planes() returns incorrect planes
  139. if the frustum is orthogonal.
  140. (Philip Hubbard)
  141. * added new framesPerSecond optional standard attribute
  142. (Florian Kainz)
  143. * Imath cleanup:
  144. - Rewrote function Imath::Quat<T>::setRotation() to make it
  145. numerically more accurate, added confidence tests
  146. - Rewrote function Imath::Quat<T>::slerp() using Don Hatch's
  147. method, which is numerically more accurate, added confidence
  148. tests.
  149. - Rewrote functions Imath::closestPoints(), Imath::intersect(),
  150. added confidence tests.
  151. - Removed broken function Imath::nearestPointOnTriangle().
  152. - Rewrote Imath::drand48(), Imath::lrand48(), etc. to make
  153. them functionally identical with the Unix/Linux versions
  154. of drand48(), lrand48() and friends.
  155. - Replaced redundant definitions of Int64 in Imath and IlmImf
  156. with a single definition in ImathInt64.h.
  157. (Florian Kainz)
  158. * exrdisplay: if the file's and the display's RGB chromaticities
  159. differ, the pixels RGB values are transformed from the file's
  160. to the display's RGB space.
  161. (Florian Kainz)
  162. * Added new lossy B44 compression method. HALF channels are
  163. compressed with a fixed ratio of 2.28:1. UINT and FLOAT
  164. channels are stored verbatim, without compression.
  165. (Florian Kainz)
  166. Version 1.4.0a:
  167. * Fixed the ReleaseDLL targets for Visual Studio 2003.
  168. (Barnaby Robson)
  169. Version 1.4.0:
  170. * Production release.
  171. * Bug Fix: calling setFrameBuffer() for every scan line
  172. while reading a tiled file through the scan line API
  173. returns bad pixel data. (Paul Schneider, Florian Kainz)
  174. Version 1.3.1:
  175. * Fixed the ReleaseDLL targets for Visual Studio 2005.
  176. (Nick Porcino, Drew Hess)
  177. * Fixes/enhancements for createDLL.
  178. (Nick Porcino)
  179. Version 1.3.0:
  180. * Removed openexr.spec file, it's out of date and broken to
  181. boot.
  182. (Drew Hess)
  183. * Support for Visual Studio 2005.
  184. (Drew Hess, Nick Porcino)
  185. * When compiling against OpenEXR headers on Windows, you
  186. no longer need to define any HAVE_* or PLATFORM_*
  187. macros in your projects. If you are using any OpenEXR
  188. DLLs, however, you must define OPENEXR_DLL in your
  189. project's preprocessor directives.
  190. (Drew Hess)
  191. * Many fixes to the Windows VC7 build system.
  192. (Drew Hess, Nick Porcino)
  193. * Support for building universal binaries on OS X 10.4.
  194. (Drew Hess, Paul Schneider)
  195. * Minor configure.ac fix to accomodate OS X's automake.
  196. (Drew Hess)
  197. * Removed CPU-specific optimizations from configure.ac,
  198. autoconf's guess at the CPU type isn't very useful,
  199. anyway. Closes #13429.
  200. (Drew Hess)
  201. * Fixed quoting for tests in configure.ac. Closes #13428.
  202. (Drew Hess)
  203. * Use host specification instead of target in configure.ac.
  204. Closes #13427.
  205. (Drew Hess)
  206. * Fix use of AC_ARG_ENABLE in configure.ac. Closes
  207. #13426.
  208. (Drew Hess)
  209. * Removed workaround for OS X istream::read bug.
  210. (Drew Hess)
  211. * Added pthread support to OpenEXR pkg-config file.
  212. (Drew Hess)
  213. * Added -no-undefined to LDFLAGS and required libs to LIBADD
  214. for library projects with other library dependencies, per
  215. Rex Dieter's patch.
  216. (Drew Hess)
  217. * HAVE_* macros are now defined in the OpenEXRConfig.h header
  218. file instead of via compiler flags. There are a handful of
  219. public headers which rely on the value of these macros,
  220. and projects including these headers have previously needed
  221. to define the same macros and values as used by OpenEXR's
  222. 'configure', which is bad form. Now 'configure' writes these
  223. values to the OpenEXRConfig.h header file, which is included
  224. by any OpenEXR source files that need these macros. This
  225. method of specifying HAVE_* macros guarantees that projects
  226. will get the proper settings without needing to add compile-
  227. time flags to accomodate OpenEXR. Note that this isn't
  228. implemented properly for Windows yet.
  229. (Drew Hess)
  230. * Platform cleanups:
  231. - No more support for IRIX or OSF1.
  232. - No more explicit support for SunOS, because we have no way to
  233. verify that it's working. I suspect that newish versions of
  234. SunOS will just work out of the box, but let me know if not.
  235. - No more PLATFORM_* macros (vestiges of the ILM internal build
  236. system). PLATFORM_DARWIN_PPC is replaced by HAVE_DARWIN.
  237. PLATFORM_REDHAT_IA32 (which was only used in IlmImfTest) is
  238. replaced by HAVE_LINUX_PROCFS.
  239. - OS X 10.4, which is the minimum version we're going to support
  240. with this version, appears to have support for nrand48 and friends,
  241. so no need to use the Imath-supplied version of them anymore.
  242. (Drew Hess)
  243. * No more PLATFORM_WINDOWS or PLATFORM_WIN32, replace with
  244. proper standard Windows macros. (Drew Hess)
  245. * Remove support for gcc 2.95, no longer supported. (Drew Hess)
  246. * Eliminate HAVE_IOS_BASE macro, OpenEXR now requires support for
  247. ios_base. (Drew Hess)
  248. * Eliminate HAVE_STL_LIMITS macro, OpenEXR now requires the ISO C++
  249. <limits> header. (Drew Hess)
  250. * Use double quote-style include dirctives for OpenEXR
  251. includes. (Drew Hess)
  252. * Added a document that gives an overview of the on-disk
  253. layout of OpenEXR files (Florian Kainz)
  254. * Added sections on layers and on memory-mapped file input
  255. to the documentation. (Florian Kainz)
  256. * Bug fix: reading an incomplete file causes a deadlock while
  257. waiting on a semaphore. (Florian Kainz)
  258. * Updated documentation (ReadingAndWritingImageFiles.sxw) and
  259. sample code (IlmImfExamples):
  260. Added a section about multi-threading, updated section on
  261. thread-safety, changed documentation and sample code to use
  262. readTiles()/writeTiles() instead of readTile()/writeTile()
  263. where possible, mentioned that environment maps contain
  264. redundant pixels, updated section on testing if a file is
  265. an OpenEXR file.
  266. (Florian Kainz)
  267. * Multi-threading bug fixes (exceptions could be thrown
  268. multiple times, some operations were not thread safe),
  269. updated some comments, added comments, more multithreaded
  270. testing.
  271. (Florian Kainz)
  272. * Added multi-threading support: multiple threads
  273. cooperate to read or write a single OpenEXR file.
  274. (Wojciech Jarosz)
  275. * Added operator== and operator!= to Imath::Frustum.
  276. (Andre Mazzone)
  277. * Bug fix: Reading a PIZ-compressed file with an invalid
  278. Huffman code table caused crashes by indexing off the
  279. end of an array.
  280. (Florian Kainz)
  281. Version 1.2.2:
  282. * Updated README to remove option for building with Visual C++ 6.0.
  283. (Drew Hess)
  284. * Some older versions of gcc don't support a full iomanip
  285. implemenation; check for this during configuration.
  286. (Drew Hess)
  287. * Install PDF versions of documentation, remove old/out-of-date
  288. HTML documentation. (Florian Kainz)
  289. * Removed vc/vc6 directory; Visual C++ 6.0 is no longer
  290. supported. (Drew Hess)
  291. * Updated README.win32 with details of new build system.
  292. (Florian Kainz, Drew Hess)
  293. * New build system for Windows / Visual C++ 7 builds both
  294. static libraries and DLLs.
  295. (Nick Porcino)
  296. * Removed Imath::TMatrix<T> and related classes, which are not
  297. used anywhere in OpenEXR.
  298. (Florian Kainz)
  299. * Added minimal support for "image layers" to class Imf::ChannelList
  300. (Florian Kainz)
  301. * Added new isComplete() method to InputFile, TiledInputFile
  302. etc., that checks if a file is complete or if any pixels
  303. are missing (for example, because writing the file was
  304. aborted prematurely).
  305. (Florian Kainz)
  306. * Exposed staticInitialize() function in ImfHeader.h in order
  307. to allow thread-safe library initialization in multithreaded
  308. programs.
  309. (Florian Kainz)
  310. * Added a new "time code" attribute
  311. (Florian Kainz)
  312. * exrmaketiled: when a MIPMAP_LEVELS or RIPMAP_LEVELS image
  313. is produced, low-pass filtering takes samples outside the
  314. image's data window. This requires extrapolating the image.
  315. The user can now specify how the image is extrapolated
  316. horizontally and vertically (image is surrounded by black /
  317. outermost row of pixels repeats / entire image repeats /
  318. entire image repeats, every other copy is a mirror image).
  319. exrdisplay: added option to swap the top and botton half,
  320. and the left and right half of an image, so that the image's
  321. four corners end up in the center. This is useful for checking
  322. the seams of wrap-around texture map images.
  323. IlmImf library: Added new "wrapmodes" standard attribute
  324. to indicate the extrapolation mode for MIPMAP_LEVELS and
  325. RIPMAP_LEVELS images.
  326. (Florian Kainz)
  327. * Added a new "key code" attribute to identify motion picture
  328. film frames.
  329. (Florian Kainz)
  330. * Removed #include <Iex.h> from ImfAttribute.h, ImfHeader.h
  331. and ImfXdr.h so that including header files such as
  332. ImfInputFile.h no longer defines ASSERT and THROW macros,
  333. which may conflict with similar macros defined by
  334. application programs.
  335. (Florian Kainz)
  336. * Converted HTML documentation to OpenOffice format to
  337. make maintaining the documents easier:
  338. api.html -> ReadingAndWritingImageFiles.sxw
  339. details.html -> TechnicalIntroduction.sxw
  340. (Florian Kainz)
  341. Version 1.2.1:
  342. * exrenvmap and exrmaketiled use slightly less memory
  343. (Florian Kainz)
  344. * Added functions to IlmImf for quickly testing if a file
  345. is an OpenEXR file, and whether the file is scan-line
  346. based or tiled. (Florian Kainz)
  347. * Added preview image examples to IlmImfExamples. Added
  348. description of preview images and environment maps to
  349. docs/api.html (Florian Kainz)
  350. * Bug fix: PXR24 compression did not work properly for channels
  351. with ySampling != 1.
  352. (Florian Kainz)
  353. * Made template <class T> become template <class S, class T> for
  354. the transform(ObjectS, ObjectT) methods. This was done to allow
  355. for differing templated objects to be passed in e.g. say a
  356. Box<Vec3<S>> and a Matrix44<T>, where S=float and T=double.
  357. (Jeff Yost, Arkell Rasiah)
  358. * New method Matrix44::setTheMatrix(). Used for assigning a
  359. M44f to a M44d. (Jeff Yost, Arkell Rasiah)
  360. * Added convenience Color typedefs for half versions of Color3
  361. and Color4. Note the Makefile.am for both Imath and ImathTest
  362. have been updated with -I and/or -L pathing to Half.
  363. (Max Chen, Arkell Rasiah)
  364. * Methods equalWithAbsError() and equalWithRelError() are now
  365. declared as const. (Colette Mullenhoff, Arkell Rasiah)
  366. * Fixes for gcc34. Mainly typename/template/using/this syntax
  367. correctness changes. (Nick Ramussen, Arkell Rasiah)
  368. * Added Custom low-level file I/O examples to IlmImfExamples
  369. and to the docs/api.html document. (Florian Kainz)
  370. * Eliminated most warnings messages when OpenEXR is compiled
  371. with Visual C++. The OpenEXR code uses lots of (intentional
  372. and unintended) implicit type conversions. By default, Visual
  373. C++ warns about almost all of them. Most implicit conversions
  374. have been removed from the .h files, so that including them
  375. should not generate warnings even at warning level 3. Most
  376. .cpp files are now compiled with warning level 1.
  377. (Florian Kainz)
  378. Version 1.2.0:
  379. * Production-ready release.
  380. * Disable long double warnings on OS X. (Drew Hess)
  381. * Add new source files to VC7 IlmImfDll target. (Drew Hess)
  382. * Iex: change the way that APPEND_EXC and REPLACE_EXC modify
  383. their what() string to work around an issue with Visual C++
  384. 7.1. (Florian Kainz, Nick Porcino)
  385. * Bumped OpenEXR version to 1.2 and .so versions to 2.0.0 in
  386. preparation for the release. (Drew Hess)
  387. * Imath: fixed ImathTMatrix.h to work with gcc 3.4. (Drew Hess)
  388. * Another quoting fix in openexr.m4. (Drew Hess)
  389. * Quoting fix in acinclude.m4 for automake 1.8. (Brad Hards)
  390. * Imath: put inline at beginning of declaration in ImathMatrix.h
  391. to fix a warning. (Ken McGaugh)
  392. * Imath: made Vec equalWith*Error () methods const.
  393. * Cleaned up compile-time Win32 support. (Florian Kainz)
  394. * Bug fix: Reading a particular broken PIZ-compressed file
  395. caused crashes by indexing off the end of an array.
  396. (Florian Kainz)
  397. Version 1.1.1:
  398. * Half: operator= and variants now return by reference rather
  399. than by value. This brings half into conformance with
  400. built-in types. (Drew Hess)
  401. * Half: remove copy constructor, let compiler supply its
  402. own. This improves performance up to 25% on some
  403. expressions using half. (Drew Hess)
  404. * configure: don't try to be fancy with CXXFLAGS, just use
  405. what the user supplies or let configure choose a sensible
  406. default if CXXFLAGS is not defined.
  407. * IlmImf: fixed a bug in reading scanline files on big-endian
  408. architectures. (Drew Hess)
  409. * exrmaketiled: Added an option to select compression type.
  410. (Florian Kainz)
  411. * exrenvmap: Added an option to select compression type.
  412. (Florian Kainz)
  413. * exrdisplay: Added some new command-line options. (Florian Kainz)
  414. * IlmImf: Added Pixar's new "slightly lossy" image compression
  415. method. The new method, named PXR24, preserves HALF and
  416. UINT data without loss, but FLOAT pixels are converted to
  417. a 24-bit representation. PXR24 appears to compress
  418. FLOAT depth buffers very well without losing much accuracy.
  419. (Loren Carpenter, Florian Kainz)
  420. * Changed top-level LICENSE file to allow for other copyright
  421. holders for individual files.
  422. * IlmImf: TILED FILE FORMAT CHANGE. TiledOutputFile was
  423. incorrectly interleaving channels and scanlines before
  424. passing pixel data to a compressor. The lossless compressors
  425. still work, but lossy compressors do not. Fix the bug by
  426. interleaving channels and scanlines in tiled files in the
  427. same way as ScanLineOutputFile does. Programs compiled with
  428. the new version of IlmImf cannot read tiled images produced
  429. with version 1.1.0. (Florian Kainz)
  430. * IlmImf: ImfXdr.h fix for 64-bit architectures. (Florian Kainz)
  431. * IlmImf: OpenEXR now supports YCA (luminance/chroma/alpha)
  432. images with subsampled chroma channels. When an image
  433. is written with the RGBA convenience interface, selecting
  434. WRITE_YCA instead of WRITE_RGBA causes the library to
  435. convert the pixels to YCA format. If WRITE_Y is selected,
  436. only luminance is stored in the file (for black and white
  437. images). When an image file is read with the RGBA convenience
  438. interface, YCA data are automatically converted back to RGBA.
