This MR proposed to add basic Radiance RGBE format
.hdr import/export functionality to Krita.
Import code is based on KImageFormats as they're indeed can parse RGBE images, but the results are always in uint8, aka.
QImage::Format_RGB32. And export code is inspired from https://www.graphics.cornell.edu/~bjw/rgbe.html
Some format limitation:
- Flattened image
- No color profile, exported image will be always converted to float, linear sRGB
- No alpha
- Build Krita
- Try to open RGBE(.hdr) image and confirm if the image is imported correctly
- Also try to export HDR image to RGBE format and check on other apps like Blender or Gimp to confirm it exported correctly
I confirmed this builds.
I confirmed Krita ran and the relevant functions work.
I tested the relevant unit tests and can confirm they are not broken. (If not possible, don't hesitate to ask for help!)
I made sure my commits build individually and have good descriptions as per KDE guidelines.
I made sure my code conforms to the standards set in the HACKING file.
I can confirm the code is licensed and attributed appropriately, and that unattributed code is mine, as per KDE Licensing Policy.
Reminder: the reviewer is responsible for merging the patch, this is to ensure at the least two people can build the patch. In case a patch breaks the build, both the author and the reviewer should be contacted to fix the build. If this is not possible, the commits shall be reverted, and a notification with the reasoning and any relevant logs shall be sent to the mailing list, firstname.lastname@example.org.
