[Eclipse 3.2M3, gtk]
Does SWT support portable saving of an image in a lossless format?
My problem is that after painting on my GC, I try to save it with:
ImageLoader loader = new ImageLoader();
loader.data = new ImageData[]{myImage.getImageData()};
...
loader.save(outfile, SWT.IMAGE_GIF);
however under linux, the image always returns 24 bit-direct ImageData, and
my only option to save this appears to be as a JPG (i.e. GIF doesn't
support 24-bit, and PNG has no encoder). Unfortunately, the JPG encoder
appears to use a hard-coded quality setting.
Pointers/ideas appreciated.
Jason.

Save SWT Image as BMP and pipe output to Jimi (image library from
Sun) that can save PNG and many other formats. May be you can even use
some standard image library in Java.
