[platform-swt-dev] XBM to GIF conversion

[Simon Meaden <simonmeaden@xxxxxxxxxxxxxxxx>]

Hi,

I am writing (intermittantly when I have time) two addons to the 
FileFormat class XBMFileFormat and XPMFileFormat to read X-Windows XBM & 
XPM files. They both read and display fine and I am now checking that 
they can save as well. Now they save fine in their own formats but I am 
having trouble saving across formats. When I save an XBM as a GIF the 
image is unreadable, however when I save the GIF as a different GIF the 
same thing happens. I am assuming that this is possible. Here is a 
snippet of my test code.

   protected ImageLoader loaderXBM = new ImageLoader();
   protected ImageLoader loaderGIF = new ImageLoader();

   ImageData[] imageDataGif = 
loaderGIF.load("/workspace/graphics/harp.gif");
   ImageData[] imageDataXBM = loaderXBM.load("/workspace/test/harp.xbm");

   loaderXBM.save("/workspace/test/harp_xbm.gif", SWT.IMAGE_GIF);
   loaderGIF.save("/workspace/test/harp_gif.gif", SWT.IMAGE_GIF);

The two images are both the same, the file harp.xbm and harp.gif (which 
was converted from the xbm using gimp) and their ImageData objects are 
identical except for their types.

Any suggestions would be appreciated.

Regards
