libraw window will show and error message after clicking ok


SOFTWARE/OS VERSIONS

I believe Krita just doesn't support this file format yet. From HDR formats, at least PNG, EXR and KRA all support HDR images, probably there are even more formats. I would suggest (for now, until Krita gets .hdri support) converting those files to .exr and only then loading to Krita.

Setting to wish since it's a new feature.

Indeed, thank you! I thought it was been introduced, that's why this bug report.

[FEATURE] Add support for Radiance RGBE

The patch adds basic Radiance RGBE format `.hdr` import/export functionality 
to Krita.
Related: bug 384136

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
