Demand for AVIF support on the web is growing, as the word gets out
about this new file format which allows higher-quality encoding at
smaller sizes. Core contributors to major open-source CMSs are
interested in auto-generating AVIF images! They've been simply
waiting for support to appear in libgd.
This PR aims to meet the growing demand, and to help bring smaller,
more beautiful images to more of the web - to sites created by
experienced developers and CMS users alike.
This PR adds support by incorporating libavif in addition to the
existing libheif support. It's generally felt that libavif has
more complete support for the AVIF format. libavif is also used
by the Chromium project and squoosh.app.
In this PR, I've endeavored to incorporate the latest research into
best practices for AVIF encoding - not just for default quantizer
values, but also an algorithm for determining the number of
horizontal tiles, vertical tiles, and threads.
Fixes#557.
With the adoption of AVIF by Firefox and Chromium based browsers (still
in experimental phase), the newer incorporation of HEIF by Canon and Sony
in their cameras and the newer support of both of them in modern software
like ImageMagick, GIMP and Krita, `gd` haven't seen any endorsement for
the formats up until this PR.
Reading and writing is done by `libheif`, with functionality for chroma
subsampling (for now `4:2:0`, `4:2:2` and `4:4:4`), quality (with new
`200` for lossless) and compression (whether `HEVC` or `AV1`) selection.
This was tested with `libheif` version `1.11.0` in my Solus machine.
Also, fixes both #395 and #557.
* FindLIQ.cmake: add comment of LIQ_BUILD which is used in CMakeLists.txt
And fixed some indent error.
* FindLIQ.cmake: delete download libimagequant source code logic.
* And delete the LIQ_BUILD logic in CMakeLists.txt correspondingly.
* Fixed some indent errors.
* FindLIQ.cmake: Delete libimagequant download path
Git ident attributes were in most cases utilized with SVN and keywords
substitutions, where $Id$ were replaced with certain revision from the
repository. In Git this functionality is different. Each $Id$ needs to
be defined in .gitattributes file to be effective. This patch removes
unused and outdated attributes.
Pull out the library versioning info out of configure and into a common
script that both cmake & autotools can run. This way we have a single
source of truth for the versioning info.
The standard behavior in distros nowadays is to build shared libs and
omit static libs. Split the build knobs in cmake to support this. It
also matches what's available with the autotools build.
There's no way to properly/fully clean a cmake build when it's configured
in-tree because they only really want to support out-of-tree builds. Add
a custom script to handle this instead.
The symbol was being set up in cmake but not on the autotools side.
Clean this up to be like other external libraries.
We need to pull in some openmp logic as it's not uncommon for the lib
to be built with openmp support. When we test for it, we need to do
so with openmp flags.
Fixes#137.
This makes the test code a lot easier to manage rather than copying &
pasting the same boiler plate multiple times.
Also take the opportunity to add a common prefix to each test name so
we don't get collisions between subdirs if a test happens to use the
same exact name.
