      1 Version 1.7.1:
      2         * Updated the .so verison to 7.
      3 	  (Piotr Stanczyk)     
      4 
      5 Version 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 
     86 Version 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 
    100 Version 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 	
    132 Version 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 
    179 Version 1.4.0a:
    180 	* Fixed the ReleaseDLL targets for Visual Studio 2003.
    181 	  (Barnaby Robson)
    182 	
    183 Version 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 
    189 Version 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 	
    195 Version 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 
    298 Version 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 
    359 Version 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 
    397 Version 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 
    417 Version 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 	
    467 Version 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 	
    520 Version 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 	
    535 Version 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)

    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.

    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 	
    606 Version 1.0.4:
    607         * OpenEXR is now covered by a modified BSD license.  See LICENSE

    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 
    637 Version 1.0.2:
    638 
    639         * More OS X fixes in Imath, IlmImf and IlmImfTest.

    646 	* Makefile.am cleanups.
    647 	* OS X fixes.
    648         * removed images directory (now distributed separately).

    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
