Description Mathias Homann 2012-08-14 13:29:26 UTC

When I try to open a .tga in gwenview, all I get is a red X and the error "Failed to read metadata".

Reproducible: Always

Steps to Reproduce:
1. try to open a .tga file
2. observe that it does not work. error message: "failed to read metadata"

Comment 1 Mathias Homann 2012-08-31 21:10:06 UTC

as of now (KDE 4.9.0) neither digikam nor gwenview nor limoo can handle TGA images.
That is a grave lack of functionality for me since I work with TGA a lot in game content development.

Comment 2 Christoph Feck 2012-08-31 22:02:17 UTC

What I see here, is that Qt 4.8.2 provides it's own plugin for TGA loading, that does not work. Can you please check if removing file "/usr/lib/qt4/plugins/imageformats/libqtga.so" helps?

Comment 3 Mathias Homann 2012-09-01 07:22:04 UTC

nope, removing the qt tga plugin did not help.

Comment 4 Christoph Feck 2012-09-01 12:55:12 UTC

Could you provide a link to a TGA file which does not open with KDE's plugin?

Comment 5 Mathias Homann 2012-09-01 13:57:02 UTC

I attached two targa files that I just created in gimp. One is 512x512 with alpha channel, the other is 512x512 without alpha channel. both do not open in gwenview.

targa file with alpha channel

Comment 8 Christoph Feck 2012-09-01 15:19:43 UTC

Both of them open fine in Kolourpaint and using a simple QImage test program, so the KDE image plugin works correctly.

If unsure, use "strace" to check which plugin gets loaded.

Comment 9 Mathias Homann 2012-09-01 16:03:07 UTC

hmm on my system, kolourpaint refuses to open those files, "unsupported format".

strace output from trying to open a TGA in kolourpaint

Here's a strace of me trying to open a tga in kolourpaint.

Comment 11 Christoph Feck 2012-09-01 23:58:32 UTC

> open("/usr/lib64/qt4/plugins/imageformats/libqtga.so", O_RDONLY) = 9

Remove that file. Then try again.

Comment 12 Mathias Homann 2012-09-02 07:58:06 UTC

that did it. thanks! I'll file a bug against openSUSE qt now and close this here as wontfix :)
