Description Emmanuel Touzery 2009-09-21 20:20:08 UTC

Version:            (using KDE 4.3.1)
OS:                Linux
Installed from:    Ubuntu Packages

when attempting to scan images from gwenview (plugins->import->scan images), the preview looks perfectly fine, however when I'm actually scanning and saving the image is corrupted.
This happens both when saving to PNG and JPG.

If I scan the same image with xsane there is no problem.

The problem occurs whether I scan the full page or a selection.

This is a bearpaw 1200 CU scanner.

I'll attach an example of corrupted picture created by this software.

Comment 1 Emmanuel Touzery 2009-09-21 20:25:19 UTC

well the image is too big for the KDE bugzilla but I also previously created an ubuntu bug for this...

so here's the image from the ubuntu bugzilla:

the ubuntu bug is otherwise:

I think I know the reason. I'll take a look at it tonight.

Comment 4 Emmanuel Touzery 2009-09-22 07:21:36 UTC

I'm using ubuntu karmic so the versions are:

libksane0 (4:4.3.1-0ubuntu1) 
kipi-plugins (0.5.0-1ubuntu1)

SVN commit 1026910 by sars:

Revert commit 998596: "Fix crash when saving images in .tiff format"
998596 broke saving 8bit color images.

This should fix 208107 "corrupted image when saving a scan" and has should not break 200558 again as there was another fix for that.

I can now save 8 and 16 bit PNG, and 8 bitt TIFF, but the 16bit TIFFs are corrupted.
