Bug#406203: krita displays a black image instead of the expected 16-bit integer/channel ppm image



Package: krita
Version: 1:1.6.1-1
Severity: important

Hi !

I noticed a strange behaviour while opening a 16-bit integer/channel
Portable Pixmap Image, created and saved with krita.

One possible way to reproduce this is to :
- open krita and create a new Custom Document,
- choose RGB 16-bit integer/channel for the color space and sRGB built-in
(lcms internal) for the profile,
- draw whatever you want,
- save it as a Portable Pixmap Image (ppm),
- close krita,
- reopen with krita the file you have just saved,
- you obtain a completely black image :-(

Note that opening the same file with ImageMagick's 'display' displays the
file correctly.


I'm not an image format specialist so I hope not to have missed something
obvious here...
Feel free to drop me an email if you need more details.

Cheers,
