OpenImageIO 1.8 has been released! The tag is "Release-1.8.5", and the
"release" branch marker has been updated to this commit. FYI, there were no
code changes for the beta and RC period over the last few weeks, so it's still
called 1.8.5.
Release 1.8 is hereby the release branch we recommend for production and
commercial use. Although we will continue to fix bugs and make enhancements
(with roughly monthly releases), we will try very hard not to ever break
backwards compatibility within the 1.8 branch.
We will still continue to fix bugs in 1.7, but only for critical bugs or if
requested by somebody who is still using 1.7 and for some reason can't upgrade
to 1.8 yet.
Meanwhile, the "master" branch is the development area for what will some day
be 1.9, and although it's used in production every day, we don't guarantee API
continuity until it's a release branch.
The release notes for 1.8 are below. Please take note of the new dependency
requirements and some changes to the installation area directory layout.
Release 1.8 (1.8.5 - 1 Oct 2017) -- compared to 1.7.x
----------------------------------------------
New minimum dependencies:
* **C++11** (should also build with C++14 and C++17)
* **Compilers**: gcc 4.8.2 - gcc 7, clang 3.3 - 5.0, or MSVS 2013 - 2017
* **Boost >= 1.53** (tested up through 1.65)
* **CMake >= 3.2.2** (tested up through 3.9)
* **OpenEXR >= 2.0** (recommended: 2.2)
* (optional) **Qt >= 5.6**
* (optional) **Python >= 2.7** (3.x is also ok)
**Changes to install layout**: fonts now get installed to
`PREFIX/share/fonts/OpenImageIO`, OIIO docs now get installed to
`PREFIX/share/doc/OpenImageIO`, and the Python module gets installed to
`PREFIX/lib/pythonMAJ.MIN/site-packages`. #1747 #1760 (1.8.5)
Major new features and improvements:
* New oiiotool features:
* `--info:format=xml` format option requests what format the info
is printed. Current choices: `"text"`, `"xml"`. #1504 (1.8.0)
* `--info:verbose=1` verbose option make file info print full metadata,
but without needing to make other oiiotool operations verbose as would
happen with `--info -v`. #1504 (1.8.0)
* `--colormap` applies a color map based on the input values; the
map can be one of several named ones, or given explicitly with
numerical values. #1552 (1.8.1)
* `-i:type=...` lets you override the internal buffer type that will be
used for an input image. #1541 (1.8.1)
* `-i:ch=a,...` lets you restrict the input to only the listed channels.
This is semantically equivalent to following the input with a `--ch`
command, but by integrating into the input itself, it can sometimes
avoid using memory and I/O for unneeded channels. #1541 (1.8.1)
* `--echo STRING` prints the string to the console. This can contain
expressions! So you can do something like
oiiotool file.exr -echo "Size is {TOP.width}x{TOP.height}"
#1633 (1.8.3)
* `--eraseattrib REGEX` erases all metadata attributes from the top image
whose names match the regular expression. #1638 (1.8.3)
* `--text` takes new optional modifiers: `xalign=` (left, right, center)
and `yalign=` (baseline, top, bottom, center) to control how the text
is aligned to the (x,y) position specified, `shadow=` (default = 0)
than when nonzero controls the width of a "drop shadow" that makes the
text clearer when rendered on a background image of similar color.
#1646 (1.8.3)
* `--deepholdout` culls all samples that are farther away than the
opaque depth of a second holdout image. #1691 (1.8.4)
* New ImageBufAlgo functionality:
* `color_map()` applies a color map based on the input values; the
map can be one of several named ones, or given explicitly with
numerical values. #1552 (1.8.1)
* Added implementation of ImageBufAlgo::to_IplImage(). #1461 (1.7.9/1.8.1)
* `render_text()` has added parameters controlling text alignment and
drop shadows. #1646 (1.8.3)
* `deep_holdout()` culls all samples that are farther away than the
opaque depth of a second holdout image. #1691 (1.8.4)
* DICOM file format support (currently read-only). DICOM is the standard for
medical imaging data. Will only build if dependency "dcmtk" is found at
build time. #1534 (1.8.1)
* Experimental: The TextureSystem API has been extended to support batches
of texture lookups in a SIMD fashion. At present, only the new API was
added, a full implementation is in progress and may not be forthcoming
or reliable until 1.9. Even the API is experimental, and may change for
future releases. #1733 (1.8.5)
Public API changes:
* TypeDesc:
* Rational support: new 'semantic' hint RATIONAL and TypeDesc::Rational.
A rational is an int of aggregate VEC2 and hint RATIONAL, and should
be interpreted as val[0]/val[1]. #1698 (1.8.5)
* Added OIIO-scoped `static constexpr` versions of preconstructed
TypeDescs (e.g., `TypeFloat`). We are deprecating the ones that were
static data members of TypeDesc (e.g., TypeDesc::TypeFloat), they will
be removed in some future release. (1.8.5)
* ImageSpec:
* New `ImageSpec::serialize()` returns a string with a serialized version
of the contents of the ImageSpec. It may be text (human readable, like
is printed by `oiiotool -info -v`) or XML. #1504 (1.8.0)
* `ImageSpec` has a new constructor that accepts a `ROI` for image
dimensions and channels. #1646 (1.8.3)
* New `ImageSpec::channelspec()` retrieves the index of a named channel.
#1691 (1.8.4)
* New `ImageSpec::channelname(int)` safely retrieves the index of a named
channel. #1706 (1.8.5)
* ColorConig::createLookTransform() and createDisplayTransform() have been
extended to allow multiple key/value context pairs, by making them
comma-separated lists. The createColorProcessor() method has also been
extended to take context key/value pairs. #1542 (1.7.8, 1.8.0)
* `ImageBuf::read()` now has a variety that takes a channel range, allowing
you to populate an ImageBuf with a subset of channels in a file,
potentially saving memory and I/O for the unneeded channels. #1541 (1.8.1)
* Python: Fix unimplemented ImageBufAlgo.computePixelStats. #1596
(1.8.2/1.7.11)
* imageio.h: Fix incorrect declaration of declare_imageio_format().
#1609 (1.8.2/1.7.11)
* `ImageBuf::wrap_mode_from_string()` converts string wrap mode names
(such as "black") into `ImageBuf::WrapMode` enum values. #1615 (1.8.3)
* New `OIIO::getattribute()` queries:
* `"input_format_list"` and `"output_format_list"` return comma-separated
lists of all formats that support input and output, respectively.
#1577 (1.8.3)
* `"oiio:simd"` returns a comma-separated list of SIMD capabilities that
were enabled at build time, and `"hw:simd"` returns the list of
capabilities available on the currently running hardware. #1719 (1.8.5)
* `ImageBufAlgo::render_text()` API call has been overhauled, in addition
to new alignment and shadow aprameters, the color has changed from a raw
pointer to an `array_view<const float>` for better memory safety. Also,
it is now valid for the destination image to be uninitialized, in which
case it will be initialized to be just big enough for the text.
#1646 (1.8.3)
* DeepData:
* New `DeepData::opaque_z()` returns the depth value at which a pixel
becomes fully opaque. #1691 (1.8.4)
* New `DeepData::initialized()` and `allocated()` return whether the
DD is initialized and allocated, respectively. #1691 (1.8.4)
* `DeepData::split()` has been changed to return a `bool` indicating
whether any split occurred. #1691 (1.8.4)
* Remove some long-deprecated varieties of `ImageBufAlgo::colorconvert()`,
`ociolook()`, and `ociodisplay()`. #1695 (1.8.4)
* TypeDesc now allows specification of "rational" values, using a vec2i
(aggregate 2-vector of int) with a semantic hint of RATIONAL, i.e.,
`TypeDesc(INT, VEC2, RATIONAL)`, which is also aliased as
`TypeDesc::TypeRational`. The value is understood to be val[0]/val[1].
#1698 (1.8.5)
* ParamValueList::get_float will automatically convert rational values to
float. #1698 (1.8.5)
* The standard metadata "FramesPerSecond" has had its definition changed
from `float` to `rational`. Retrieving it as `float` should still work
as always. But apps and plugins that wish to treat it as a true rational
with no loss of precision are able to do so. This is only known to
directly affect the OpenEXR, GIF, and FFMPEG metadata. #1698 (1.8.5)
Fixes, minor enhancements, and performance improvements:
* oiiotool:
* `--chappend` resolves redundant channel names by using the subimage
name, if available. #1498 (1.8.0/1.7.8)
* `--mosaic` now gracefully handles the case of not having enough
images to completely fill the MxN matrix, with "left over" slots
black. #1501 (1.8.0/1.7.8)
* When command line arguments fail to parse properly, `oiiotool` will
exit with a non-zero shell status. #1540 (1.8.0)
* `--colorconvert`, `--ociodisplay`, and `--ociolook` can now take
multiple context key/value pairs (by allowing `key=` and `value=`
optional paramters be comma-separated lists). #1504 (1.8.0)
* Handle 'oiiotool --colorconvert X X' (transform from and to spaces that
are the same) without considering it an error. #1550 (1.8.0/1.7.8)
* Expression substitution now recognizes the following new metadata
names: MINCOLOR, MAXCOLOR, AVGCOLOR. An example use is to stretch
the value range of an image to fill the full [0-1] range:
oiiotool in.exr -subc {TOP.MINCOLOR} -divc {TOP.MAXCOLOR} -o out.exr
#1553 (1.8.1)
* `--fit:exact=1` use of the new `exact=1' option will perform the resize
to preserve exact aspect ratio and centering of the fit image to true
sub-pixel precision (at the possible risk of slight blurring,
especially of the edges), whereas the default (`exact=0`) will keep
the image sharper but round the size and offset to the nearest whole
pixel values. (1.8.1).
* `-i:type=...` optional modifier to `-i` forces a read of the input
file into a particular data type. #1541 (1.8.1)
* `-i:ch=...` optional modifier to `-i` specifies that only certain named
channels should be read from the file. Under extreme circumstances
when only a small subset of channels is needed from an image file with
many channels, this may improve speed and I/O. #1541 (1.8.1)
* Improved logic governing output data formats: non-cached inputs didn't
set default output data format correctly, and per-channel output
formats updated defaults when they shouldn't have. #1541 (1.8.1)
* `--diff` : in addition to the pixel coordinates and differences of the
biggest differing pixel, it now also prints the full values of all
channels of that pixel for both images. #1570 (1.8.1)
* `oiiotool -d` giving per-channel formats is no longer confused by
channel renaming with `--chnames`. #1563 (1.8.1/1.7.9)
* `--debug` nor prints the total runtime and peak memory use after each
individual op. #1583 (1.8.1)
* `-iconfig` not in all cases correctly propagate the input config
attribute to the file read. #1605 (1.8.2/1.7.11)
* Fixed `--crop`: it did not honor the `-a` flag to apply the crop to
all subimages. #1613 (1.8.2/1.7.11)
* In the case of runtime errors, `oiiotool` now echoes the entire command
line. This is helpful for debugging mangled oiiotool command lines
assembled by scripts. #1614 (1.8.3)
* Improved error reporting of file open errors when -iconfig is used.
#1626 (1.8.3/1.7.13)
* Expression evaluation now substitutes `FRAME_NUMBER` with the numeric
frame number for frame sequence wildcards, and `FRAME_NUMBER_PAD`
with the frame number 0-padded to the number of total digits specified
by the command line `--framepadding` argument. #1648 (1.8.3)
* `--resize` and `--resample` now have more intuitive behavior for images
where the display and pixel data windows are not the same, especially if
the data window had a nonzero origin (such as with crop or overscan).
#1667 (1.8.4/1.7.14)
* `--resample` has been extended to work for "deep" images. #1668
(1.8.4/1.7.14)
* `--deepmerge` now will give a useful error message when the image do
not have the same number of channels. #1675 (1.8.4/1.7.14)
* `--autocc` more gracefully handles unknown color spaces with a warning,
rather than a full error and termination. #1681 (1.8.4)
* `--resample` now takes an optional modifier `interp=0` to control
whether bilinear sample is used (default) or true closest-pixel point
sampling. #1694 (1.8.4)
* You can set rational metadata on the command line like this:
`oiiotool foo.exr --attrib:type=rational onehalf "50/100" -o rat.exr`
#1698 (1.8.5)
* `--fillholes` fixed a bug where, if asked to operate on an image with
nonzero origin (crop, overscan, shrink-wrap), it would incorrectly
move the pixels to the origin. #1768 (1.8.5)
* ImageBufAlgo:
* `channel_append()` resolves redundant channel names by using the
subimage name, if available. #1498 (1.8.0/1.7.8)
* `colorconvert()`, `ociodisplay()`, and `ociolook()` can now take
multiple context key/value pairs (by allowing they `context_key` and
`context_value` paramters be comma-separated lists). #1504 (1.8.0)
* `draw_rectangle()` (and `oiiotool --box`) wasn't drawing properly for
the degenerate case of a rectangle that takes up just one
pixel. #1601 (1.8.2)
* `resample()` has been extended to work for "deep" images.
#1668 (1.8.4/1.7.14)
* `deep_merge()` now will give a useful error message when the images do
not have the same number of channels. #1675 (1.8.4/1.7.14)
* `deep_merge()` performance has been greatly improved. #1739 (1.8.5)
* `resample()` fixed a subtle 1/2 pixel shift, now it more closely
aligns with `resize()`. #1694 (1.8.4)
* `fillholes_pushpull()` fixed a bug where, if asked to operate on an
image with nonzero origin (crop, overscan, shrink-wrap), it would
incorrectly move the pixels to the origin. #1768 (1.8.5)
* ImageBuf:
* Fix broken threads(n) method, which didn't correctly pass the right
number of threads along. #1622. (1.8.3/1.7.12)
* Copy constructor from another ImageBuf was previously broken for
IB's that wrap application buffers. #1665 (1.8.4/1.7.13)
* TextureSystem / ImageCache / maketx:
* `IC::get_image_info` (or `TS::get_texture_info`) queries for "channels"
on UDIM file patterns now succeed, returning the value for the first
matching file it finds. (N.B.: Relies on all textures within the same
UDIM set having the same nchannels.) #1502, #1519, #1530 (1.8.0/1.7.8)
* maketx: multiple simultaneous maketx process trying to create the same
texture will no longer clobber each other's output. #1525 (1.8.0/1.7.8)
* ImageCache: make robust to changes in autotile after opening and reading
from untiled files. #1566 (1.8.1/1.7.9)
* ImageCache: fix initialization bug that made the reported stats output
nonsensical in the numbers it gave for "redundant reads". #1567
(1.8.1/1.7.9)
* get_image_info queries of "displaywindow" and "datawindow" did not
correctly return a 'true' value when the data was found.
#1574 (1.8.1/1.7.9)
* maketx fix: two textures that had identical source pixels but differed
in whether they resized with "highlight compensation" incorrectly
ended up with identical hashes, and thus could be confused by the
TextureSystem at runtime into thinking they were duplicates. The hash
is now fixed. #1599 (1.8.2/1.7.11)
* Statistics no longer list as "BROKEN" files which were invalidated, or
files that were initialized with an ImageCacheFile but never opened.
#1655 (1.8.4)
* ImageCache::get_image_info() will now return a proper error (and not
hig an assertion) if asked for information about a subimage or MIP
level that does not exist in the file. #1672 (1.8.4/1.7.14)
* TextureSystem::get_texels fixes crashing behavior. #1669 (1.8.4/1.7.14)
* Big performance improvement on Windows with MSVC by removing certain
empty destructors in simd.h that was preventing MSVC from fully inlining
those classes. #1685 (1.8.4/1.7.15)
* maketx now supports `--colorconfig` option to explicitly point it to
an OpenColorIO config file, just like `oiiotool `--colorconfig`.
#1692 (1.8.4)
* Fix rare edge case crash in ImageCache. #1696 (1.8.4/1.7.15)
* Improved error messages for broken files. Specifically, it's much more
clear now when a file is broken because it's being rejected as a
texture because it's untiled or not MIP-mapped. #1751 (1.8.5)
* The maketx-generated metadata "oiio:SHA-1", "oiio:ConstantColor" and
"oiio:AverageColor" are ignored if the file has signs that it was not
directly generated by `maketx` or `oiiotool -otex` (specifically, if
it's not tiled, has no "textureformat" tag, or if its "software" tag
doesn't mention maketx or oiiotool). This helps for the case where a
maketx-generated file is loaded into PhotoShop (or otherwise altered),
saved with different pixel values but the old SHA-1, which would no
longer be valid and therefore cause the new file to be misidentified
as a duplicate texture even though it's not. #1762 (1.8.5)
* Bug fix to possible crashes when adding dither to tiled file output
(buffer size miscalculation). #1518 (1.8.0/1.7.8)
* Make sure that sRGB<->linear color transform still work (in the obvious
way) even when OpenColorIO is present but that its configuration for some
reason doesn't know about "sRGB" space. #1554 (1.8.1)
* Improved performance of input of many-channel files with differing
per-channel data formats. #1541 (1.8.1)
* `idiff` : in addition to the pixel coordinates and differences of the
biggest differing pixel, it now also prints the full values of all
channels of that pixel for both images. #1570 (1.8.1)
* ImageInput::read_tiles when only a channel subset is read, fixed case
with certain data sizes where the copy to user buffer got mangled.
#1595 (1.8.2/1.7.11)
* BMP:
* Add support for version 5 of the BMP format header. $1616 (1.8.3/1.7.12)
* FFMpeg/movies:
* "FramesPerSecond" metadata has had its type changed to rational.
#1709 (1.8.5)
* GIF:
* "FramesPerSecond" metadata has had its type changed to rational.
#1709 (1.8.5)
* IFF:
* Fix IFF output that didn't correctly save the "Author" and "Date"
metadata. #1549 (1.8.1/1.7.8)
* JPEG:
* Be more reslient to malformed Exif data blocks with bogus offsets
#1585 (1.8.1/1.7.10) and #1639 (1.8.3/1.7.13).
* When you ask the JPEG writer to output files with unsupported channel
counts (JFIF files only allow 1 or 3 channels), it will just silently
drop extra channels, rather than having a hard error. #1643 (1.8.3)
* OpenEXR:
* Fix global attribute "exr_threads" value, -1 should disable IlmImf's
thread pools as advertised. #1582 (1.8.1)
* Allow compression "none" for deep exr files. (1.8.2/1.7.11)
* Fixed input problem with sorting order of spectral alpha channels (RA,
GA, BA, or AR, AG, AB). #1674 (1.8./1.7.14)
* Can handle true rational metadata, including FramesPerSecond and
captureRate. #1698 (1.8.5)
* Fix problem with 2-channel images putting the channels in the wrong
order. #1717 (1.8.5/1.7.16)
* PNG: Better extraction of XMP from PNG files. #1689 (1.8.4)
* PSD:
* Support has been added for "cmyk", "multichannel", and "grayscale"
color modes. And support was fixed for rgb and grayscale 32 bit per
sample bit depth. #1641 (1.8.3/1.7.13)
* Fix issue for layer mask channels. #1714 (1.8.5)
* RAW:
* Fix possible crash when reading certain raw metadata. #1547 (1.7.8/1.8.0)
* The default value for missing "raw:use_camera_matrix" has been changed
to 1 (not 0) to better match default behavior of libraw/dcraw.
#1629 (1.8.3/1.7.13)
* Add support for selecting new demosaicing algorithms: "DMT" (mode 11)
and "AAHD" (mode 12). Renamed the "Modified AHD" to "AHD-Mod" to
simplify and match libraw terminology. Made matching of demosaicing
algorithms case-insensitive. #1629 (1.8.3/1.7.13)
* Support "ACES" color space for direct conversion while reading RAW
images (supported in libraw 0.18 or newer). #1626 (1.8.3/1.7.13)
* Add "raw:user_sat" configuration attribute to the reader.
#1666 (1.7.15/1.8.4)
* The pixels are now decoded (expensive) only when they are read, not
when the file is first opened. This makes raw reading much faster for
apps that are only interested in the metadata and not the pixel data.
#1741 (1.8.5)
* Unpack pixels when they are needed, not when the file is opened. This
makes it much faster to read RAW file only to extract the metadata,
if you don't need the pixel values. #1741 (1.8.5)
* RLA:
* Fix RLA reading and writing with certain channel orders and mixded data
formats. #1499 (1.8.0/1.7.8)
* TIFF:
* Fix to TIFF handling of certain unusual tags. #1547 (1.7.8/1.8.0)
* Now has a way to read raw pixel values from CMYK files, without
the automatic conversion to RGB (pass configuration attribute
"oiio:RawColor" set to nonzero). #1605 (1.8.2/1.7.11)
* Improved I/O of color separation images, particularly those with
custom InkSet attributes. #1658 (1.8.4/1.7.15)
* Fix typo that prevented correct reading of some Exif fields. #1625
(1.8.3/1.7.12)
* TIFF output omitted setting the "Make" and "Model" metadata tags.
#1642 (1.8.3/1.7.13)
* Images with fewer than 4 channels, but one of those channels was alpha,
were not correctly marking spec.alpha_channel. #1718 (1.8.5/1.7.16)
* The XPOSITION and YPOSITION tags are now interpreted as relative to
the RESOLUTIONUNIT, whereas before it was assumed to be measured in
pixels. We are confident that the new way is more in line with the
intent of the TIFF spec. #1631 (1.8.5)
* webp:
* Several new sanity checks prevent the webp reader from spending too
much I/O time and memory reading bogus files (malformed, corrupted,
or not a webp after all). #1640 (1.8.3/1.7.13)
* Nuke plugin: Fix txReader to properly restore saved MIP level knob value.
#1531 (1.8.0)
* Fixed several (so far unnoticed) buffer overruns and memory leaks.
#1591 (1.8.2)
* TIFF, JPEG, others: Improved reading Exif meatdata from XMP blocks, now it
does a better job of discerning the proper data types. #1627 (1.8.3/1.7.13)
* In several places, the formatting of date metadata has been changed to
have a leading zero rather than leading space for hours < 10, i.e.,
"02:00:00" rather than " 2:00:00". #1630 (1.8.3)
* Improve XMP parsing (for any format): for malformed XMP, still honor the
parts that could be parsed properly; recognize additinoal tags for
GPano (Google's Photo Sphere metadata schema) and camera raw (crs: prefix)
metadata; improve speed of XMP parsing. #1679 (1.8.4)
* Improved handling and color conversion of gamma-corrected images (DPX,
HDR, PNG, RLA, Targa) by supporting linearization correctly even in the
presence of OCIO configs that don't know about it. #1684 (1.8.4)
* Fixed static initialization order fiasco error involving interaction
between ColorConfig and Strutil. #1757 (1.8.5)
Build/test system improvements:
* **Changes to install layout**: fonts now get installed to
`prefix/share/fonts/OpenImageIO`, OIIO docs now get installed to
`prefix/share/doc/OpenImageIO`, and the Python module gets installed to
`prefix/lib/pythonMAJ.MIN/site-packages`. #1747 #1760 (1.8.5)
* Support for building against ffmpeg 3.1 (their API has changed).
#1515 (1.8.0/1.7.8)
* Build no longer gets confused about include files from older installations
of OIIO elsewhere on the system. #1524 (1.8.0/1.7.8)
* Improvements in finding OpenJPEG. #1520 (1.8.0/1.7.8)
* Improved finding of OCIO headers. #1528 (1.8.0/1.7.8)
* Fix compile warnings for Clang 3.9. #1529 (1.8.0/1.7.8)
* Minimum C++ standard of C++11 is expected and enforced. #1513 (1.8.0)
* Minimum Boost is now 1.53. #1526 (1.8.0)
* Fix compiler warning on Fedora aarch64. #1592 (1.8.1)
* Tweak OpenJPEG include file search rules to prefer newer versions when
multiple are installed. #1578 (1.8.1)
* Build option `SANITIZE=...` lets us use the sanitizers. #1591 (1.8.2)
* Big refactoring of the cmake build files. #1604 (1.8.2)
* When using a recent enough C++ compiler and standard library, OIIO will
now use C++11 std::regex rather than boost regex. #1620,#1644 (1.8.3)
* Support for clang-tidy using build time flags CLANG_TIDY=1,
CLANG_TIDY_ARGS=..., and optionally CLANG_TIDY_FIX=1. #1649 (1.8.4)
* Fix Windows warnings about SIMD types as function arguments
and about bool vs int. #1659 (1.8.4)
* Changed the way namespaces work. Instead of a 2-level namespace, make a
one-level namespace, and automatically embed the major and minor version
in it. (Can stll override the basename.) #1662 (1.8.4)

* Fix python site-packages path for installation. #1722 (1.8.5)
* Fixes for building with gcc 7. (1.8.5)

* Simplify CMake scripts by using GNUInstallDirs to set standard installation
paths. #1747 (1.8.5)
Developer goodies / internals:
* Sysutil::Term formatting now works properly in Windows (though is only
functional for Windows 10 or above). (1.8.0/1.7.8) #1527
* C++11 idioms:
* We now eschew BOOST_FOREACH, in favor of C++11 "range for". #1535
* We now use std::unique_ptr, no longer use boost::scoped_ptr or
boost::scoped_array. #1543 (1.8.0) #1586 (1.8.1)
* Instead of the various boost components, we now use `std::` versions of
unordered_map, unordered_set, shared_ptr, hash, bind. #1586 (1.8.1)
* Change deprecated C headers (such as `<ctype.h>`) to C++ (`<cctype>`).
#1649 (1.8.4)
* Use `std::vector<>::emplace_back()` where applicable. #1657 (1.8.4)
* Mark ImageInput/ImageOutput derived classes as 'final'. (1.8.5)
* array_view.h:
* Add front() and back() methods. #1724 (1.8.5)
* Simplified array_view template to be 1D only. #1734 (1.8.5)
* atomic.h:
* Added atomic_min and atomic_max. #1661 (1.8.4)
* Added atomic_fetch_add for `std::atomic<float>` and double. #1661 (1.8.4)
* Assume std::atomic is available, remove all code that is only needed
for pre-C++11. #1661 (1.8.4)
* benchmark.h:
* New `Benchmarker` class utility for micro-benchmarking. #1577 (1.8.5)
* Moved time_trial, timed_thead_wedge, DoNotOptimize, clobber_all_memory
to benchmark.h. #1577 (1.8.5)
* errorhandler.h: Change all ErrorHandler methods to use variadic templates
rather than varargs. #1653 (1.8.4)
* filesystem.h:
* Better exception safety for Filesystem::searchpath_find. #1680
(1.8.4/1.7.15)
* fmath.h:
* Fixed typo in fmath.h that made bitcast_to_float incorrect. #1543 (1.8.0)
* Templatize round_to_multiple() so it works with types other than `int`.
#1548 (1.8.0)
* `interpolate_linear()` utility linearly interpolates from a list of
evenly-spaced knots. #1552 (1.8.1)
* Slight reformulation of clamp() ensures sane results even with NaN
parameters. #1617 (1.8.3)
* Bug fixes to `ifloor()` and `floorfrac()`, which turned out to give
incorrect results for exact negative integer values. Also added
simd vector-based versions of `floorfrac`. #1766 (1.8.5)
* paramlist.h:
* ParamValueList has been refactored and now inherets from, rather than
containts, a `std::vector<ParamValue>`. This removes most of the
additional code from the class. #1677 (1.8.4)
* ParamValue new methods: `get<>()`, `get_int()`, `get_float()`,
`get_string()`, `get_ustring()` retrieve and convert. #1686 (1.8.4)
* ParamValueList new methods: `get_int()`, `get_float()`, `get_string()`,
`get_ustring()` search, retrieve, and convert (much like the
equivalent versions in ImageSpec did). #1686 (1.8.4)
* Remove the pointless typedefs `ImageIOParameter` and
`ImageIOParameterList` in favor of `ParamValue` and `ParamValueList`,
respectively. #1690 (1.8.4)
* platform.h:
* More `cpu_has_...()` tests for newer CPU capabilties. #1719 (1.8.5)
* Remove deprecated OIIO_NOTHROW macro, which should now simply be
C++11 `noexcept`. #1736 (1.8.5)
* strutil.h / Strutil:
* Add `Strutil::printf()` and `Strutil::fprintf()`, typesafe and
non-thread-jumbled replacements for C versions. #1579, #1656 (1.8.1, 1.8.4)
* `from_string<>` has been extended to 'unsigned int'. (1.8.3/1.7.13)
* `Strutil::parse_identifier_if` #1647 (1.8.3)
* safe_strcpy now takes a string_view, and more closely conforms to the
behavior of strncpy by filling in the extra space with 0 padding.
(1.8.5)
* simd.h:
* Add a matrix44 constructor from 16 floats. #1552 (1.8.1)
* Renamed files floatN, intN, boolN to vfloatN, vintN, vboolN, to avoid
confusion with bit lengths of scalars. #1719 (1.8.5)
* Overhaul to support AVX-512 via vfloat16, vint16, vbool16 classes.
#1719 (1.8.5)
* load_mask, store_mask, and scatter/gather added for all types.
#1732 (1.8.5)
* Renamed `floori()` to `ifloor()` to match the analogous scalar function
in fmath.h. #1766 (1.8.5)
* strided_ptr.h: The `strided_ptr<>` template is now also templated on
the stride units -- the default is to measure strides in units of
sizeof(T), but it's possible to override and measure in bytes (the old
behavior). #1758 (1.8.5)
* thread.h:
* thread_pool class offers true persistent thread pool.
#1556, #1581 (1.8.1)
* Lots of C++ modernization of thread_group and spin_mutex. #1556 (1.8.1)
* Environment variable `OPENIMAGEIO_THREADS` can artificially raise or
lower the default number of threads (otherwise, it defaults to the
number of processor cores available). #1581 (1.8.1)
* timer.h: added timed_thread_widge() that benchmark code and prints
statistics about thread scaling. #1660 (1.8.4)
* typedesc.h:
* Modernized TypeDesc with C++11 constexpr where applicable. #1684 (1.8.4)
* New `TypeDesc::basevalues()` method. #1688 (1.8.4)
* unittest.h:
* Colored error messages and auto error return on completion. #1731 (1.8.5)
* *NEW* parallel.h:
* parallel_for, parallel_for_chunked, parallel_for_each offer simple
thread_pool-based parallel looping in 1 and 2 dimensions.
#1556, #1581 (1.8.1)
* Internal `OIIO::debugmsg()` call has been renamed to `OIIO::debug()`,
and setting env variable OPENIMAGEIO_DEBUG_FILE can redirect the debug
messages to a file. #1580 (1.8.1)
* Upgraded tinyformat to the latest master, also changed all the places
where we used TINYFORMAT_WRAP_FORMAT to use of C++11 variadic templates.
#1618 (1.8.3)
* *NEW* function_view.h : function_view<> is a very lightweight, non-owning,
generic callable object view. Cheaper than std::function, but the view
is not allowed to outlive the callable object it references. #1660 (1.8.4)
* Deprecate the pre-C++11 macros OIIO_CONSTEXPR, OIIO_CONSTEXPR_OR_CONST,
and OIIO_NOEXCEPT. #1678 (1.8.4)
Docs:
* Improve docs about deep IBA functions. (1.8.1)
* Fix 'Building OIIO on Windows' link. #1590 (1.8.1)
