Convert Image from BMP to GIF [message #466989]

I have an SWT canvas that I can save without any problems to BMP and
Jpeg. Is it possible to save it as a GIF?

Or, does anyone have a code example that will convert an SWT Image to
transparent GIF? Thanks!

The following snippet saves an animated gif - your case will be simpler but
similar:

I just figured this out with some trial and error. In case anyone else
is interested, this is how I took an SWT image from a canvas and turned
it into a PNG with alpha transparency:

Convert the SWT image to AWT (found a code snippet online)
Get the pixels from the AWT image
If the pixel is white (or whatever color you want to be transparent)
perform a 0x00 >> pixel, else do pixel << 0x00 to store in a new one
dimensional array
Use AWT Component's createImage function get a new AWT image
Save the AWT using Jimi with the PNGEncoder

you make me think of an image converte. it will convert into the most common used formats. so BMP to GIF is simple i guess.
