[platform-swt-dev] 'Unsupported color depth' error on Linux

[Rajeev Sikka <sikkar@xxxxxxxxxx>]

Hi,

I have the following code sequence:

...
Image image = ...
...
ImageData imageData = image.getImageData();
...
ImageLoader imageLoader = new ImageLoader();
imageLoader.save(..., SWT.IMAGE_GIF);
...

This runs fine on windows but gives
'Unsupported color depth' error on Linux. The reason is that the code for
Image::getImageData() is different for Windows and Linux. On Linux the
returned ImageData object has color depth 24 (on windows its 8). Here is
the code snippet from Image.java on Linux:

ImageData data = "" ImageData(width,
height, 24, palette);

Subsequently, the function ImageLoader::save
which indirectly calls unloadIntoByteStream(ImageData ) in file GIFFileFormat.java
throws a SWT.error, since valid color depths are only 1, 4, and 8.

Is there any workaround/alternative
way to get around this?

Thanks,
Rajeev
