What am I missing? KDE/Dolphin unable to generate tga thumbnails.


I can seem to get thumbnails for most everything else, but .tga image files will not generate thumbnails naturally. If I open the image in GIMP, then a thumbnail is generated (until I save over the file).

Is there a component I am missing and need to install, or is this a bug with KDE/Dolphin?

I am using Kubuntu 13.10 with KDE 4.11.5

It's not just you. I also cannot seem to get Dolphin to display thumbnails of a targa image. I'd never noticed that before as I use mostly tiff and exr for the big graphic files.

Unless there's an additional package for Dolphin that includes this function, you may have a feature request on your hands.

Well, glad to hear it's not something only I'm having happen. I just found it odd that it'll generate the thumbnail only if I open the image in GIMP (possibly another program, I don't think I have anything else installed that'll open tga images).

Have you tried saving the targa WITHOUT compression? It seems, possibly, that Dolphin may be able to thumbnail-ize a targa not using internal compression.

Where are the targas coming from originally? blender or photoshop or other?

Also it seems png, and gif images don't thumbnail either. As for the images, the original image sources sometimes vary, but they're all re-created with GIMP. Though some of the source image files I use for templates or sampling, also do not work.

You've probably already done this, but just to make sure:

In Dolphin: go to Settings [Menu] > Configure Dolphin

In Configure Dolphin window: Click on the General tab on the left.

In General panel: click the Preview Tab at the top, and make sure there are tick marks by:
- Images (GIF, PNG, BMP,...)
- JPEG Images
- EXR Images

Also at the bottom of that screen, notice that it gives a value for "Do not create previews for,,,". Set the "Local files above" to something fairly large, as long as your machine is half way capable of that sort of thing.

Click Apply or OK or whatever, and things should be better in your life.

Don't know how that setting got unticked, but still no bmp or tga support, and tga is that I work with the most (due to one of the softwares I use being able to only use tga).

This is a local folder, I just have the path hidden.

I'm assuming it's some kind of compression (with the targa files) that's getting turned on by the generating application. I know in GIMP there's an option to not use the compression and that does render, for me, thumbnails. As for .bmp, I have very little exprerience with those and don't really know the variables involved.

I'd probably file a bug with KDE on this one, though. I can't think of any good reason these files should not be thumbnail'd.

Yeah, off to bug reporting I suppose. The .bmp files are completely uncompressed images, and I've already tried with an uncompressed targa.
