We have tagged Release-1.6.9 (no longer release candidate) within the RB-1.6 branch.
The 'RB-1.6' marker points to the very latest commit at the head of this branch, but not necessarily to a tagged, approved release. The 'release' marker always indicates the latest tagged release of the current stable release branch (currently points to Release-1.6.9). This is the one we endorse for use in conservative production or for embedding in shipping products. We will not break API or link compatibility within the 1.6 branch, although we will occasionally tag new releases incorporating bug fixes or low-risk feature additions. All 1.6 releases will continue to remain compatible with C++03 (and whatever compilers or libraries it currently builds against). The 'master' branch contains current development. It tends to be fairly bug-stable (and is used straight from the head at a number of production studios, including my own employers), but is definitely not API-stable or link-stable. So if you need those assurances, you are advised to stick with the 'release' branch. >From here on out, 1.5 is considered to be legacy code, no longer directly >supported except to occasionally patch important bug fixes. Generally >speaking, I will do so only when requested by somebody who is still stuck >using 1.5 and will tend not to spontaneously fix it. As a final warning, let me reiterate that the current master/1.7 will assume the http://www.vfxplatform.com/ recommendations for 2016 releases, requiring a minimum of gcc 4.8.3 (or clang 3.4, or MSVS 2013 [I think]) and C++11. At this very moment, it still builds as C++03, but we are making no effort to ensure that moving forward. You are warned that if your facility or product requires C++03 compatibility, you must stay on a 1.6 release and should not be using the current master. I am also expecting that at some point in the development of 1.7, we will remove any cruft that assumes versions dependent libraries older than the VFX Platform 2016 guidelines (notably, we will stop supporting OpenEXR 1.x and certain old Boost versions). Below is a mostly complete list of all the changes made in the course of development of 1.6. Enjoy. Release 1.6 (released Dec 21, 2015) -- compared to 1.5.x ---------------------------------------------- Major new features and improvements: * New oiiotool functionality: * Expression evaluation/substitution on the oiiotool command line. Anything enclosed in braces { } in a command line argument will be substituted by the evaluation of the enclosed expression. Expressions may be numbers, simple arithmetic (like 'expr+expr'), or retrieving image metadata from named images or images on the stack. Please see the PDF documentation, Section 12.1 for details and examples. * --absdiff, --absdiffc compute the absolute difference (abs(A-B)) of two images, or between an image and a constant color. #1029 (1.6.0) * --abs computes the absolute value of an image. #1029 (1.6.0) * --div, divc divide one image by another (pixel by pixel), or divides the pixels of an image by a constant color. #1029 (1.6.0) * --addc, --subc, --mulc, --powc are the new names for --cadd, --csub, --cmul, and --cpow. The old ones will continue to work but are considered depcrected. #1030 (1.6.0) * --pattern supports new patterns: "fill" makes a solid, vertical or horizontal gradient, or four-corner interpolated image (just like the --fill commmand) (1.6.0); "noise" can generate uniform, gaussian, or salt & pepper noise (1.6.2). * --fill, in addition to taking optional parameter color=... to give a solid color for the fill region, now also takes top=...:bottom=... to make a vertical gradient, left=...:right=... to make a horizontal gradient, and topleft=...:topright=...:bottomleft=...:bottomright=... to make a 4-corner gradient. (1.6.0) * --noise adds noise to the current image: additive uniform or gaussian noise, or making "salt & pepper" noise. (1.6.2) * --trim crops the image to the minimal rectangle containing all the non-0 pixels. (1.6.3) * --autocc : when turned on, automatic color conversion of input files into a scene_linear space, and conversion to an appropriate space and pixel type upon output. It infers the color spaces based on metadata and filenames (looking for OCIO-recognized color space names as substrings of the filenames). #1120 (1.6.3) * --mad takes three image arguments, multiplies the first two and then adds the third to it. #1125 (1.6.3) * --invert computes the color inverse (1-value) for color channels. #1125 (1.6.3) * --colorconfig allows you to specify a custom OCIO configuration file (rather than strictly relying on the $OCIO env variable). #1129 (1.6.3) * --deepen converts flat images to "deep". #1130 (1.6.3) * -n (no saved output) performs all calculations (including timing and stats) but does not write any output files to disk. #1134 (1.6.3) * --debug prints debugging information, this is now separate from -v which just makes more verbose (non-debugging) output. #1134 (1.6.3) * --pixelaspect rescales the image to have the given pixel aspect ratio. #1146 (1.6.5) * --ociofiletransform() implements OpenColorIO "file" transforms. #1213 (1.6.5) * New ImageBufAlgo functions: * absdiff() computes the absolute difference (abs(A-B)) of two images, or between an image and a constant color. #1029 (1.6.0) * abs() computes the absolute value of an image. #1029 (1.6.0) * div() divides one image by another (pixel by pixel), or divides all the pixels of an image by a constant color. #1029 (1.6.0) * fill() has been extended with new varieties that take 2 colors (making a vertical gradient) and 4 colors (one for each ROI corner, for a bilinearly interpolated gradient). (1.6.0) * noise() injects noise into an image -- uniform, gaussian/normal, or salt & pepper noise. (1.6.2) * mad() multiplies the first two arguments and then adds the third to it. #1125 (1.6.3) * invert() computes 1-val. #1125 (1.6.3) * deepen() turns a flat RGBA (and optional Z) image into a "deep" image. #1130 (1.6.3) * ociofiletransform() implements OpenColorIO "file" transforms. #1213 (1.6.5) * Some open source fonts are now distributed with OIIO (DroidSans, DroidSans-Bold, DroidSerif, DroidSerif-Bold, DroidSerif-Italic, DroidSerif-BoldItalic, and DroidSansMono), and so those are always available to ImageBufAlgo::render_text() and oiiotool --text, on all platforms and even if you don't have any other installed fonts on your system. DroidSans is now the default font. #1132 (1.6.3) * GIF output support (including writing animated GIF images, just write it as a multi-subimage file). For example, this works: oiiotool foo*.jpg -siappendall -attrib FramesPerSecond 10.0 -o anim.gif #1193 (1.6.4) Public API changes: * TypeDesc: * New helper methods: is_array(), is_unsized_array(), is_sized_array(). #1136 (1.6.3) * New constructor and fromstring of a string_view, in addition to the old versions that took char*. #1159 (1.6.4/1.5.16) * New aggregate type: MATRIX33. #1265,#1267 (1.6.6) * ImageSpec: * ImageSpec::metadata_val() is now static, rather than simply const, since it doesn't need access to *this at all. #1063 (1.6.1) * Added a new variety of find_attribute that takes a temporary ImageIOParameter as scratch space. The advantage of this call is that it can retrieve items from the named ImageSpec fields, such as "width", "full_x", etc. Also, the get_int_attribute, get_float_attribute, and get_string_attribute can now retrieve these fixed fields as well. #1063 (1.6.1) * ImageInput & ImageOutput: * New ImageOutput::supports() tags: supports("alpha") should be true for image formats that support an alpha channel, supports("nchannels") should be true for output formats that support an arbitrary number of output channels. (1.6.2/1.5.13) * ImageInput and ImageOutput supports() method has been changed to accept a string_view (rather than a const std::string&), and return an int (rather than a bool). (1.6.2) * ImageInput and ImageOutput have added destroy() static methods. They are just wrappers around 'delete', but can help you to ensure that II and IO objects are deleted on the same side of a DLL boundary as where they were created. (Helps with using OIIO from DLL-based plugins on Windows.) (1.6.3) * New ImageInput query: "procedural" -- returns 1 if the ImageInput may not correspond to an actual file. #1154 (1.6.4/1.5.16) * ImageInput and ImageOutput's error() method is changed from protected to public, making it easier for an app to set an error on a reader or writer. (1.6.4) * ImageOutput::copy_to_image_buffer is a helper function that generalizes the existing copy_tile_to_image_buffer, but for any rectangle. #1193 (1.6.4) * ImageInput::read_image() variant that takes a channel range to read just a subset of the channels present. #1222 (1.6.5) * ImageInput and ImageOutput now have new method threads(n) that sets the thread "fan-out" for the ImageInput or ImageOutput individually, overriding any global attribute("threads"). #1259 (1.6.6) * ImageBuf: * Add make_writeable(), which forces ImageCache-backed read-only ImageBuf to read into locally allocated pixels so they can be subsequently altered. #1087 (1.6.2) * ImageBuf::Iterator has added set_deep_samples() and set_deep_value() methods. (1.6.3) * ImageBuf::set_pixels() now provides a way to set an arbitrary rectancle of an ImageBuf from raw values. #1167 (1.6.4) * ImageBuf::get_pixels() now has a variety that takes an ROI to describe the rectangle of pixels being requested. #1167 (1.6.4) * ImageBuf now has new method threads(n) that sets the thread "fan-out" for the ImageInput or ImageOutput individually, overriding any global attribute("threads"). #1259 (1.6.6) * ImageCache/TextureSystem: * Clarified in the docs that TextureSystem::get_texture_info and ImageCache::get_image_info "exists" queries should return true, and place in *data the value 1 or 0 depending on whether the image exists and can be read. (1.6.0/1.5.10) * Added handle-based versions of TextureSystem get_texture_info(), get_imagespec(), imagespec(), and get_texels(), in addition to the existing name-based versions of those methods. Note that texture(), environment(), and texture3d() already had both name-based and handle-based varieties. #1057 (1.6.1) #1083 (1.6.2) * Add create_thread_info() and destroy_thread_info() methods that allow an app to manage the per-thread records needed by the IC. #1080 (1.6.2) * Added ImageCache get_perthread_info() and get_image_handle() to return opaque perthread and file handle pointers, much like TextureSystem already had, and added handle-based versions of get_image_info(), get_imagespec(), imagespec(), get_pixels(), and get_tile(), in addition to the existing name-based versions of those methods. #1057 (1.6.1) * ImageCache get_tile and get_pixels have new varieties that let you request channel begin/end range. This allows you to control which channel ranges are in the cache, and thus be much more efficient with cache storage when only a few channels are needed from a file with many channels. #1226 (1.6.5) * ImageBufAlgo: * New ImageBufAlgo functions: abs, absdiff, div, fill, noise, mad, invert, deepen, ociofiletransform. * nchannels() now takes an 'nthreads' parameters, just like all the other ImageBufAlgo functions. #1261 (1.6.6) * Python bindings: * Added previously-M.I.A. ImageSpec::erase_attribute(). #1063 (1.6.1) * ImageSpec.set_channel_formats() now works when the channel type lists are either TypeDesc, in addition to the existing support for BASETYPE. #1113 (1.6.3/1.5.13) * Added Python bindings for DeepData and deep reads (ImageInput) and writes (ImageOutput), as well as additional DeepData and ImageBuf methods to fully match the C++ API. #1113 #1122 (1.6.3/1.5.13) * ImageBuf.set_pixels, and ImageBuf.get_pixels with ROI. #1167,1179 (1.6.4) * Change Python ImageOutput bindings to simplify the write_* methods. They no longer take both a TypeDesc and an array; it can figure out the type from the array itself. Also get rid of the stride parameters, which weren't useful in a Python context. #1184 (1.6.4) * ImageBufAlgo colorconvert, ociolook, and ociodisplay now take an optional string colorconfig argument. #1187 (1.6.4) * Fix missing Python bindings for global OIIO::getattribute(). #1290 (1.6.8) * The ColorConfig wrapper for OCIO functionality has been extended to parse color names from filename strings, and to report the recommended pixel data type for a color space. #1129 (1.6.3) * C++11 definitions: oiioversion.h defines OIIO_BUILD_CPP11 as nonzero if OIIO itself was built in C++11 (or later) mode, and platform.h defines OIIO_USING_CPP11 as nonzero if at this moment C++11 (or later) mode is detected. Note that these can differ if one set of compiler flags was used to build OIIO, and a different set is used to build a project that uses OIIO headers. #1148 (1.6.4) * Renamed the "fps" standard metadata to "FramesPerSecond. #1193 (1.6.4) * Removed deprecated header "string_ref.h" (use string_view.h). (1.6.1) * oiioversion.h: Renamed the namespace macros OIIO_NAMESPACE_ENTER/EXIT to OIIO_NAMESPACE_BEGIN/END, and roll the braces into it. #1196 (1.6.4) * array_view.h: Refactor array_view to be more in line with what is slated for C++17, in particular it is now templated on Rank and so can be a view to a multi-dimensional array. Also change array_view_strided to have strides measured in units of sizeof(T), not bytes (to keep with C++17). This also adds coordinate.h to give definitions for the offset<>, bounds<>, and bounds_iterator<> templates used by array_view. #1205 (1.6.4) * Add top-level OIIO::get_int_attribute(), get_float_attribute(), and get_string_attribute() helpers, similar to how they work in many of the classes. #1283 (1.6.7) Fixes, minor enhancements, and performance improvements: * oiiotool * Bug fix for frame sequences -- could crash in Windows. #1060 (1.6.1) * Gracefully handle requests to save an image with more channels than the output file format can handle. Instead of being a fatal error, now it's just a warning, and extra channels are dropped. It tries to to find R, G, B, and A channels, saving them. If those names are not found, it just saves the first 3 (or 4) channels. #1058 (1.6.1) * Improve error messages when files can't be read. It is now easier to to distinguish files that don't exist from those that are an unknown format from those that are corrupted or have read errors. #1065 (1.6.1) * Flag errors properly when -d specifies an unknown data format name. #1077 (1.6.2/1.5.13) * oiiotool numeric wildcard improvement: allow more digits to match. #1082 (1.6.2/1.5.13) * Bug fix: input file data format didn't always end up in the output. (1.6.3) * --channels bugs were fixed when dealing with "deep" images. (1.6.3) * All the color space conversion operations run much faster now, since the underlying IBA::colorconvert() has been parallelized. (1.6.3) * --crop logic bug fixed in cases where the crop region was the same size as the original pixel data window. #1128 (1.6.3) * oiiotool now gives proper error messages when asked to perform unsupported operations on deep images. (1.6.3) * Bug fix: --frames incorrectly overrode explicit frame sequence wildcards on the command line. #1133 (1.6.3) * --crop, --trim, and --autotrim have been extended to work on "deep" images. #1137 (1.6.3) * For "procedural" ImageInputs, don't give "file doesn't exist" errors. (1.6.4) * Suppress output/copying of "textureformat" metadata inherited from input if it's not plausibly still a valid texture (i.e., if it's no longer tiled or MIPmapped). #1206 (1.6.4) * oiiotool's full help message lists all supported formats. #1210 (1.6.5) * oiiotool --help prints a briefer help screen. Use --help -v for the full-detail help. #1214 (1.6.5) * Bug fix in --fit when the image didn't need to be resized. #1227 (1.6.5/1.5.21) * Bug fix in --ch for "deep" files when the channel reordering is the same as it already was. #1286 (1.6.7) * ImageBufAlgo: * compare() (and therefore oiiotool -diff and idiff) did not notice image differences when the pixels that differed had NaN or NaN or Inf values! Now it is right. #1109 (1.6.3/1.5.13) * channels() bugs were fixed when dealing with "deep" images. (1.6.3) * colorconvert() has been parallelized, and thus on most systems will now run much faster. (1.6.3) * render_text() handles UTF-8 input. #1121 (1.6.3) * colorconvert(), ociodisplay(), and ociolook() have new varities that accept an optional ColorConfig, rather than having no choice but to construct a new one internally. (1.6.3) * nonempty_region() and crop() have been extended to handle "deep" images. #1137 (1.6.3) * Fix bug in fft() -- was not always zeroing out the imaginary channel. #1171 (1.6.4/1.5.17) * Fixed uninitialized variable bugs with rangecompress() and rangeexpand() when using luma. #1180 (1.6.4) * The lanczos3, radial-lanczos, and catrom filters have been change from fixed-width to fully scalable. This fixes artifacts that occur when using them as upsizing filters. #1228,#1232 (1.6.5/1.5.21) * maketx, TextureSystem, and ImageCache: * TextureSystem/IC now directly stores uint16 and half pixel data in the cache rather than converting internally to float for tile storage, thus effectively doubling the cache capacity for files of those formats. (1.6.3) * Fix broken bicubic texture sampling with non-power-of-two sized tiles. #1035 (1.6.0/1.5.10) * maketx: when the source image was a crop (data window != display window), and the sharpening filters were used, it would incorrectly issue an "unknown filter name" error. #1059 (1.6.1/1.5.12) * maketx: Flag errors properly when -d specifies an unknown data format name. #1077 (1.5.13) * maketx now writes to a temporary file, then moving it to the final requested output filename only when the write completed without error. This prevents situations where maketx crashes or is killed and leaves behind a file that looks correct but is actually corrupted or truncated. #1072 (1.6.2/1.5.13) * TextureSystem bug fix that occasionally resulted in NaN in the alpha channel result when looking up from 3-channel images. #1108 (1.6.3/1.5.13) * maketx --runstats prints runtime staticstics (deprecating --stats). #1152 (1.6.4) * Fixed trilinear MIPmap texture lookups that gave invalid alpha fill. #1163 (1.6.4/1.5.16) * The lanczos3, radial-lanczos, and catrom filters have been change from fixed-width to fully scalable. This fixes artifacts that occur when using them as upsizing filters. #1228,#1232 (1.6.5) * Texture cache memory efficiency is much better for the special case of accessing just a few channels from a texture file with large numbers of channels. #1226 (1.6.5) * Eliminate spurious ImageCache invalidation just because the shared cache is requested again. #1157 (1.6.4/1.5.16) * Statistics output also shows all the option setting values. #1226 (1.6.5) * Data copy error in ImageCache::get_pixels for partial-channel-set copies. #1246 (1.6.5) * maketx -u now remakes the file if command line arguments or OIIO version changes, even if the files' dates appear to match. #1281 (1.6.8) * GIF: * Write support! #1193 (1.6.4) * On input, renamed "fps" metadata to "FramesPerSecond". #1193 (1.6.4) * IFF: * Fix botched output of 16 bit uncompressed data. #1234 (1.6.5/1.5.21) * Make "rle" compression the default. #1234 (1.6.5/1.5.21) * JPEG: * Now properly read/write xdensity and ydensity (what OIIO and TIFF call "XResolution" and "YResolution" and, therefore, "PixelAspectRatio". #1042 #1066 (1.6.0, 1.6.1) * Support JPEG files encoded as CMYK (by converting to RGB upon read) #1044 (1.6.1) * Fix misdeclared supports() which would make the JPEG plugin appear to not support exif or iptc. #1192 (1.6.4) * JPEG-2000: * Fix handling of un-premultiplied alpha (which is dictated by the JPEG-2000 spec). (1.6.3) * Fix reading of YUV-encoded files. (1.6.3) * Read and write the ICC profile, if present. (1.6.3) * Handle all bit depth precisions properly (previously only 8, 10, 12, and 16 were right). (1.6.3) * Set the full/display window correctly. (1.6.3) * Deal with differing per-channel data windows and sampling rates. (1.6.3) * OpenEXR: * Improved handling of density and aspect ratio. #1042 (1.6.0) * Fix read_deep_tiles() error when not starting at the image origin. #1040 (1.6.0/1.5.10) * Fix output of multi-part exr file when some parts are tiled and others aren't. #1040 (1.6.0/1.5.10) * write_tile() with AutoStride calculated the wrong default strides for "edge" tiles when the image width or length was not an integer multiple of the tile size. Also clarified the PDF and imageio.h docs in how they explain strides for this case. #1055 (1.6.1/1.5.12) * Fix bugs in reading deep OpenEXR images with mixed channel types. #1113 (1.6.3/1.5.13) * OpenEXR output supports("deepdata") now correctly returns 'true'. #1238 (1.6.5/1.5.21) * A separate global OIIO::attribute("exr_threads") sets the thread pool size for OpenEXR's libIlmImf, independent of the OIIO thread fan-out attribute OIIO::attribute("threads"). #1244 (1.6.5) * Correctly read and write Matrix33 and double (scalar, 2d, 3d, m33, m44) metadata. #1265,#1267 (1.6.6) * Recognize AR/AG/AB channel names in addition to the old RA/RG/RB #1277 (1.6.6) * PNG: * Writing PNG files now honors the PixelAspectRatio metadata. #1142 (1.6.3) * PFM: * PFM (float extension of PNM) was incorrectly flipped top to bottom. Now fixed. #1230 (1.6.5) * PSD: * Better error handling for files lacking "global layer mask info" or "additional layer info". #1147 (1.6.4/1.5.18) * Additional PSD signatures for global additional layer info. #1147 (1.6.4/1.5.18) * Better error handling when dealing with an empty layer mask. #1147 (1.6.4/1.5.18) * TIFF: * Improved handling of density and aspect ratio. #1042 (1.6.0) * Improved proper handling of the interplay between "XResolution", "YResolution", and "PixelAspectRatio". #1042 (1.6.0) * TIFF output: recognize special "tiff:write_exif" metadata, which when present and set to 0, will skip writing the Exif directory into the TIFF file. This can be helpful when you expect the resulting TIFF file to be read with very old versions of libtiff. #1185 (1.6.4/1.5.18) * Correct read and write of JPEG-compressed TIFF. #1207 (1.6.4) * Correct support for reading LAB, LOG, YCbCr, subsampled chroma. #1207 (1.6.4) * Make robust to strange TIFF files that have unexpected MIP level-to-MIP level changes in planarconfig, photometric, palette, extrasamples, etc. #1220,1221 (1.6.5/1.5.20) * Support output of 2, 4, 10, and 12 bit unsigned ints into TIFF files. #1216 (1.6.5) * Make TIFF reading more robust to certain subimage-to-subimage changes that were thought to be invariant. #1221 (1.6.5) * CMYK is properly read and written. Upon read, CMYK is auto-converted to RGB (and the "tiff:ColorSpace" metadata is set to "CMYK"). For output, if "tiff:ColorSpace" metadata is set and nonzero, the RGB passed in will be auto-converted to CMYK upon writing. #1233 #1245 (1.6.5) * Recognize Exif tags in the main directory, not only the special Exif directory. #1250 (1.6.5) * Fix bug in read_scanlines when reading TIFF files with UNassociated alpha and unusual ystride values. #1278 (1.6.6) * ImageBuf iterator constructors with 0-size ranges or ROIs have been fixed to look like they are immediately done(). #1141 (1.6.3) * Fix bug in internal convert_image() that could corrupt certain image copying of non-contiguous data layouts. #1144 (1.6.3) * Also search for OIIO plugins in [DY]LD_LIBRARY_PATH. #1153 (1.6.4/1.5.16) * Nuke plugin: don't crash with NULL Knob* in TxReaderFormat::setMipLabels. #1212 (1.6.5/1.5.20) * idiff -q results in quiet mode -- output nothing for success, only minimal errors to stderr for failure. #1231 (1.6.5) Build/test system improvements: * Python plugin is now build as a cmake "module" rather than "library", which fixes some things on OSX. #1043 (1.6.0/1.5.10) * Various build fixes for Windows. #1052 #1054 (1.6.1) * New CMake build-time option to specify the default plugin search path. #1056 (1.6.1/1.5.12) * Fix build breaks for very old versions of Ilmbase (1.6 and earlier) that lack a definition of V4f used by our simd.h. #1048 (1.6.1/1.5.11) * Fix signed/unsigned warning on 32 bit platforms in jpeginput.cpp. #1049 (1.6.1/1.5.11) * New CMake build-time option to specify the default plugin search path. #1056 (1.6.1/1.5.12) * Fix gcc 5.0 compiler warning in PtexHalf.cpp. (1.6.1/1.5.12) * Remove dependency of OpenSSL by default. #1086 (1.6.2/1.5.13) * Fix warnings when compiling with C++11. (1.6.3/1.5.13) * Dont link Python framework on OSX. #1099 (1.6.3/1.5.13) * Changed the way testtex warps the image to give faux perspective to test texture mapping. (1.6.3) * Build-time USE_SIMD=... has been changed from accepting a single tag to a comma-separated list of feature options. So you can, for example, do make USE_SIMD=avx,f16c ... (1.6.3) * make USE_NINJA=1 causes CMake to build Ninja build files instead of Makefiles (they execute much faster, espectially for incremental builds). #1158 (1.6.4) * PSD & JPEG plugins fixes for Win32 compilation. #1150 (1.6.4/1.5.16) * Fix Nuke plugin build files to not do anything if USE_NUKE=0. #1156 (1.6.4/1.5.16) * Builds now produce much less console output by default (use VERBOSE=1 to get all the details, most of which is only useful when debugging broken builds). #1162 (1.6.4) * Fix support for older ffmpeg version on Ubuntu 14.04. #1168 (1.6.4/1.5.17) * Build-time fixes for Nocona CPUs that have SSE3 without SSSE3. #1175 (1.6.4/1.5.17) * ustring internals fixes for gcc 5.x changs to std::string ABI. #1176 (1.6.4) * Fixes for clean build with clang 3.6. #1182,1183 (1.6.4) * Fix signed/unsigned comparison error. #1186 (1.6.4) * Top-level Makefile option USE_OPENCV=0 to turn off even searching for OpenCV components. #1194 (1.6.4/1.5.18) * If a system-installed (external) PTex implementation is found, use it. Only use the "bundled" version if no other is found. Also add a top-level USE_PTEX=0 that will skip PTex support, even if the library is found. #1195,1197 (1.6.4) * Fix compiler warnings about int vs size_t mismatches. 1199 (1.6.4) * Improve C++11 and C++14 readiness. #1200 * Fix build break with certain new versions of libraw. #1204 (1.6.4/1.5.19) * Fix build warnings for new Apple tools release that upgrades the standard clang release. #1218 (1.6.5/1.5.20) * When compiling in C++11 mode, std::unordered_map, mutex, recursive_mutex, lock_guard, bind, ref, cref, thread, shared_ptr will be used rather than boost equivalents, and our own thread_group and intrusive_ptr are now used rather than the boost equivalents. We believe that this completely removes all Boost headers and types from the OIIO public APIs when in C++11 mode. (Though internals still use Boost in some cases.) #1262 #1266 (1.6.6) * We are now set up to use Travis-CI (https://travis-ci.org) for continuous integration / automatic builds of all merges and pull requests. #1268, #1269, #1273 (1.6.6) * Don't install fonts if USE_FREETYPE is disabled. #1275 (1.6.6) * Use ccache for builds when detected and safe (unless USE_CCACHE=0). #1274,#1285 (1.6.7) * Failed tests now print their non-matching text output to the console when doing 'make test'. This makes it much easier to spot most errors. #1284 (1.6.7) Developer goodies / internals: * Strutil additions: parse_until, parse_nested (1.6.1), repeat (#1272/1.6.6/1.5.21). * Give Strutil::parse_string an option to not strip surrounding quotes. (1.6.4) * Made TypeDesc::equivalent accept comparisons of arrays of unspecified length with ones of definite length. #1072 (1.6.2/1.5.13) * Add Filesystem::rename() utility. #1070 (1.6.2/1.5.13) * New SIMD methods: insert<>, xyz0, vreduce_add, dot, dot3, vdot, vdot3, AxBxCxDx, blend0not (1.6.2) * array_view enhancements that let you initialize an array_view<const float> from a const std::vector<float>&. #1084 (1.6.2/1.5.14) * hash.h contains several new hashes in namespaces 'OIIO::xxhash' and 'OIIO::farmhash'. Also, Strutil::strhash now uses farmhash rather than the Jenkins one-at-a-time hash, bringing big speed improvements (including ustring creation). Beware that the strhash value returned will be different than they were before. #1090 (1.6.3) * fmath: safe_fast_pow improves the precision of its results for special cases of pow(x,1) and pow(x,2). #1094 (1.6.3/1.5.13) * Added TypeDesc::TypeHalf(). #1113 (1.6.3/1.5.13) * thread.h: our atomic types have had their API adjusted somewhat to more closely conform to C++11's std::atomic. (1.6.3) * ustring's internals and underlying hash table have been overhauled, yielding much higher performance, especially when many threads are simultaneously creating ustrings. (1.6.3) * ROI improvement: make intersection & union robust to uninitialized ROIs as arguments. (1.6.3) * osdep.h is deprecated. Use platform.h instead. (1.6.3) * The DISPATCH_TYPES utility macros used internally by IBA have been improved, and in particular the DISPATCH_COMMON_TYPES now handle ALL types ("uncommon" ones are silently converted to float). (1.6.3) * platform.h moves the endian functions into the OIIO namespace. (1.6.3) * platform.h adds functions for runtime query of CPU capabilities. (1.6.3) * simd.h: float4 and int4 can now construct and load from unsigned short*, short*, unsigned char*, char*, and 'half'. (1.6.3) * Strutil::utf8_to_unicode (1.6.3) * Filesystem::current_path(). #1124 (1.6.3/1.5.21) * Filesystem enumerate_file_sequence and scan_for_matching_filenames have been modified to clear their result vectors rather than simply assume they are empty. #1124 (1.6.3) * oiiotool internals have been refactored to be class-oriented and move a lot of boilerplate repeated in each op to be part of the base class. #1127 (1.6.3) * timer.h: Timer and ScopedTimer have changed slightly. This isn't used in any public OIIO APIs, but may affect 3rd party programs that like to use OIIO's timer.h for convenience. #1201 (1.6.4/1.5.19) * dassert.h: added OIIO_STATIC_ASSERT macros for static assertion. Doesn't affect existing OIIO apps since they are new additions, but feel free to use them! #1202 (1.6.4/1.5.19) * New unit test for imagecache. #1246 (1.6.5) * Sysutil::hardware_concurrency() and physical_concurrency(). #1263 (1.6.6/1.5.21) -- Larry Gritz [email protected] _______________________________________________ Oiio-dev mailing list [email protected] http://lists.openimageio.org/listinfo.cgi/oiio-dev-openimageio.org
