The goal of MR is to control the correct saving of metadata and resolution in plugins that support them.
- Modified the basic write test to verify that resolution and metadata are saved correctly.
- Verifies the correct functioning of MicroExif in plugins that use it to save metadata.
- EXR: fixed wrong vertical resolution (error found with this MR).
- Added EXR, JXR, JXL, PCX metadata test.
Improve the write test by using images with different sizes. By doing this we protect ourselves from line alignment problems (e.g. with 1-bpp images), image size divisors (e.g. power-of-2 divisors), etc...
Pros:
- The test does not add new images but reuses the ones for the format test.
Cons:
- No test are done for read only plugins.
Closes#15
- 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.
Unfortunately none of them pass since it seems they can't load a png,
save it to their format with loseless quality and read it back and get
exactly the same contents than the png
According to relicensecheck Brad is OK with changing LGPLv2 to LGPLv2+,
which is required to be compatible with the LGPL-2.1-or-later licensed
source files.
Qt also has a tga image plugin so unless we make sure ours is used first
tests are not testing what they should
On a side note their plugin fails our tests so someone with enough time
should report the failures to them
Two main tests: read the file and compare to a given image (loaded from
png), and write a file out and compare to a previously-written image.
The write test in particular is kind of fragile, but it should help
catch some errors where a code change was not intended to affect the
output of the plugin.
Tests are included for all the writable formats, as well as every
readable format that GIMP can write to (and so I could easily get an
example of).
