- Added support for writing EXR files
- Large image support (tested with 32GiB 16-bit image)
- OpenEXR multithreaded read/write support through the use of line blocks
- Build option to enable conversion to sRGB when read (disabled by default)
- Multi-view image reading support
- Options support: Size, ImageFormat, Quality, CompressRatio
- Metadata write/read support via EXR attributes
The plugin is now quite complete. It should also work on KF5 (not tested): if there is the will to include this MR also on KF5, let me know and I will do all the necessary tests.
Added support for RLE compressed images. This patch makes the player almost complete allowing to read all type 1,2 and 3 RAS files. Only types 4 and 5 are missing which are images converted from TIFF and IFF.
As a base I used the reference implementation found on the official site at https://qoiformat.org/ (MIT license).
I added a class to convert scan lines in scanlineconverter.cpp. The class takes advantage of the QImage conversion and contrary to what one might expect, with large images it improves performance (compared to converting the whole image) 😄
In progressive mode, for each line, the following conversions (only if needed) are made before saving:
1. If the icc profile is set, the line is converted to sRGB or sRGB Linear.
2. The line is scaled to 8 bits with RGBA order.
Plugin to read RAW camera images based on LibRAW.
- Supersedes MR !86
- Support to LibRaw 0.20 and 0.21-Beta
- Support to multi-shot images: use imageCount(), jumpToImage() to select the wanted shot
- By default generates 16-bits sRGB images using camera white balance and interpolation AHD
- Should fix CCBUG: 454208: on my Debian with KF5.96 and the pulgin installed, I see the preview of all my RAW files (ARW included) in Dolphin
News compared to V1 (MR !86)
- Fix possible stack overflow due to the huge size of LibRaw class
- Fix image allocation with Qt 6 (make use of QImageIOHandler::allocateImage())
- Support to XMP metapacket
- Support to quality option. For e.g. you can focus on quality (q = 10) or speed (q = 1)
- oss-fuzz available [here](https://github.com/mircomir/oss-fuzz/tree/raw_fuzz/projects/kimageformats)
They were already disabled when building with Qt >= 5.3 in commit
3d45b270ea because Qt has better plugins
for those image formats. Now that we depend on Qt 5.3 we can remove
them.

The BSD license goes in the relevant CMake file, and
COPYING-CMAKE-SCRIPTS is removed. README.md gets a License section
describing the overall license of the framework, as well as a note about
the CMake scripts.
As part of this commit, I release the existing autotest images (which I
created myself) as public domain (or license them under CC0 where public
domain does not apply), ensuring they are compatible with whatever
license the package is distributed under.
