Package: openjpeg-tools
Version: 1:1.5.2-3
Tags: patch
The TGA file writer used by j2k_to_image writes a wrong field to the
header for alpha-less images.
To reproduce:
1. Take any 24-bit j2k image with no alpha.
2. Convert it to TGA with j2k_to_image -i <image>.j2k -o <image>.tga
3. Open <image>.tga with Gimp.
When opened, the image will have a wrong alpha channel, because Gimp
uses a certain field in the header to determine if the image has alpha.
That field is saved wrongly by j2k_to_image for alpha-less images. Per
the TGA specification, Gimp is correct in this case.
The attached patch fixes this issue.
