Looking at the TGAImage class and the tga file in question, it seems to be expected...

private void decodeImage(GLProfile glp, LEDataInputStream dIn) throws IOException {
        switch (header.imageType()) {
        case Header.UCOLORMAPPED:
            throw new IOException("TGADecoder Uncompressed Colormapped images not supported");

        case Header.UTRUECOLOR:    // pixelDepth 15, 16, 24 and 32
            switch (header.pixelDepth) {
            case 16:
                throw new IOException("TGADecoder Compressed 16-bit True Color images not supported");

            case 24:
            case 32:
                decodeRGBImageU24_32(glp, dIn);
                break;
            }
            break;

        case Header.UBLACKWHITE:
            throw new IOException("TGADecoder Uncompressed Grayscale images not supported");

        case Header.COLORMAPPED:
            throw new IOException("TGADecoder Compressed Colormapped images not supported");

        case Header.TRUECOLOR:
            throw new IOException("TGADecoder Compressed True Color images not supported");

        case Header.BLACKWHITE:
            throw new IOException("TGADecoder Compressed Grayscale images not supported");
        }
    }

The exception I am thrown is:

Thank you for investigating. There is a lack to support for RLE compression in TGAImage, "truecolor" is already supported.

Which version of JOGL do you use? RLE support was added in 2013 in this class, only 16-bits compressed truecolor TGA files are still unsupported:
https://github.com/sgothel/jogl/blob/master/src/jogl/classes/com/jogamp/opengl/util/texture/spi/TGAImage.java#L279

The Gimp doesn't give me a lot of information about the image data :s

"For 16 bits each colour component is stored as 5 bits and the remaining bit is a binary alpha value."
http://www.paulbourke.net/dataformats/tga/

It matches with this format:
http://jogamp.org/deployment/jogamp-next/javadoc/jogl/javadoc/javax/media/opengl/GL.html#GL_RGB5_A1

Created attachment 606 [details]
Test case for targa image

Thanks for pointing that out, I didn't realize I was using a much older version. 

The unit test passes against master and 2.1.4.

I have attached the test if you wish to run.

9d7a7e55c95fcf29ce1ed0804fd7791c1c1147de:
  Added RLE32 tga file to be tested w/ pre-existing unit test TestTGATextureFromFileNEWT.

As mentioned above - not a bug, all works.

Sorry but it doesn't work with the image I mentioned in my very first post:
https://github.com/Renanse/Ardor3D/blob/master/ardor3d-core/src/main/resources/com/ardor3d/renderer/state/notloaded.tga

I've just added the problematic image into the unit test:
https://github.com/sgothel/jogl/pull/78

It seems to work but I still get an exception. It probably exhibits another bug elsewhere.

In JoglImageLoader, I do this:
final TextureData textureData = TextureIO.newTextureData(_capsUtil.getProfile(), is, true, null);

It has no chance to work with TGA because of this test in TGATextureProvider:
if (TGA.equals(fileSuffix)) {

I don't know yet how I'll work around this limitation.

Feel free to close this bug as invalid. The image I provided in in true color 32 bits, the problem comes from Ardor3D except if we consider that JOGL should be able to guess which image type contains the passed input stream (with a file suffix set to null). I'll implement this mechanism in Ardor3D, maybe we should move it into JOGL itself, it should be the subject of a distinct bug report.

The real bug has been fixed in Ardor3D:
https://github.com/gouessej/Ardor3D/blob/master/ardor3d-jogl/src/main/java/com/ardor3d/image/util/jogl/JoglImageLoader.java#L148

Sven, please tell me whether this kind of thing should be moved into JOGL.

My bug report is invalid as JOGL's TGA loader was already able to load the default image used in Ardor3D since the very beginning. Ardor3D AWT image loader was the only loader able to "guess" the image format until I fixed that in com.ardor3d.image.util.jogl.JoglImageLoader.

That would be _excellent_, i.e. the image format auto-detection!

IMHO it would be nice to have a static method returning the type,
as well as an overloaded 'load' texture method.

Nice!

I will cherry pick your lines and commit as you as author.
