Daniel Novomeský dd69fdaea9 lib prefix on Android 
Qt's original qtimageformats plug-ins use lib prefix too,
without the lib prefix, the image plug-ins don't work on Android.

Daniel Novomeský e9da5edb9a avif: check return values 
Some libavif calls did not return values in the older versions.
Situation changed meanwhile;
we can check the return values for error conditions now.

Daniel Novomeský da8ed31aec avif: new quality settings 
Prior libavif 1.0, quality was set using two numbers
(minQuantizer and maxQuantizer).
New versions of libavif recommend using
new/single quality parameter instead.
Compression using the new settings is different
compared to the old.
For example, new quality 68 gives similar compression
like old default 52.

It was reported by Code Quality scans as Critical (CWE-457)
 2023-08-29 21:04:00 +02:00
Daniel Novomeský 2aea982e9e qoi: fix reports from quality scanner 
struct QoiHeader is initialized to invalid values prior use,
it’s good to detect situations when we read incomplete data.
Add include in scanlineconverter.cpp so it can be used without
change in kf5 branch.

Daniel Novomeský a30f043e5d heif: rewrite plugin to use only libheif C API 
Using C-API instead of C++ libheif API has following advantages:
- More libheif features available (for ex.: strict decoding)
- Linking with static build of libheif is possible
- No need to enable exceptions
 2022-12-05 22:43:41 +01:00
Daniel NovomeskýandAlbert Astals Cid 3b1e8f7054 minor tweaks in HEIF and AVIF plugins

Daniel Novomeský afa7399b36 avif: minor fixes 
libavif 0.11.0 uses new default dimension limit 32768 pixels,
we allow 65535 which was used by us previously.
Minor tweaks in jumpToNextImage, jumpToImage
to handle rare situations.

Daniel Novomeský 3790a89cd1 avif: Use reinterpret_cast instead C cast

 2022-10-11 15:05:20 +02:00
Daniel Novomeský f475a4b24a avif: revert 9ac923ad09 commit 
Changes to libavif's avifImageRGBToYUV() API were reverted too.

Daniel Novomeský d2f38b8b9c heif: replace C cast with static_cast 2022-10-10 09:28:41 +00:00
Daniel Novomeský 9ab64dbf22 heif: use heif_init/heif_deinit with libheif 1.13.0+ 
In recent libheif, application should use
heif_init/heif_deinit calls. Unfortunately, these calls are
not thread-safe in released 1.13.0 version yet (will be in the
future) and HEIFHandler is often created in different threads.
So we have to guard their use with a mutex.

Daniel Novomeský 024d199ed0 Replace C cast with reinterpret_cast 2022-09-11 11:01:55 +02:00
Daniel Novomeský 9ac923ad09 avif: adjust for libavif breaking change in YUV<->RGB conversion 2022-09-09 17:54:18 +02:00
Daniel Novomeský 5e59d950bd jxl: support both old 0.6.1 and new 0.7.0 libjxl API 
New libjxl API changed the way how lossless 16bit depth images
must be encoded: codestream level 10 must be set,
which implies use of container format.
Unfortunately, there isn’t version number inside libjxl header yet,
so we must detect new version on cmake/PkgConfig level.

Plug-in can save in 8bit depth now,
previously only 16bit was supported.
Memory and dimension limits were adjusted.

Daniel Novomesky 6458c9ae52 avif: performance and quality improvements 
Enable decoder to use more threads.
8bit YUV->RGB conversion is significantly faster
when AVIF_RGB_FORMAT_RGBA format is used,
because libavif can use libyuv to perform conversion quickly.
Prefer faster AVIF_CHROMA_UPSAMPLING_FASTEST when decoding animation.
Encoder speed changed from to 8 to 7.
Recent AV1 encoders got faster,
so it is OK to switch to better compression quality.
Remove obsolete image/avif-sequence mime-type
as it was merged with image/avif.
 2021-09-22 11:53:46 +02:00
Daniel Novomesky ef6be2c077 avif: Disable all strict decoder checks 
New libavif 0.9.1 apply some very strict standard compliance
checks by default. Unfortunately, it rejects many files made by
libheif-based apps (GIMP, ImageMagick) in the past.
libheif 1.12.0 (released on May 5, 2021) addressed the problem,
but it would be good to extend grace period, allowing other
projects and distributions to upgrade to fixed version.

Daniel Novomesky 62f9af9a35 Color profile loading/saving fixes 
Allow saving Qt-unsupported variants of ICC profiles, they could be
correctly handled by apps with wider color management support.
Change way how QColorSpace is created to avoid
rare problems in some apps.

Daniel Novomesky 1462c3abd6 Check primaries returned from libavif 
Due to various double vs float arithmetic,
some primaries could be rejected by Qt.
If necessary, we adjust the values so they
will be accepted by Qt.

Remove newline from the ends of error strings.
