Question

I suspect the solution here is probably really simple, but I’m stumped…

// Create the buffered image. BufferedImage bufferedImage = new BufferedImage(w,h,BufferedImage.TYPE_INT_RGB);  // fill image data (works fine) ImageIO.write(bufferedImage, 'JPG', f1); // works fine ImageIO.write(bufferedImage, 'PNG', f2); // works fine ImageIO.write(bufferedImage, 'GIF', f3); // this returns false, creates a broken gif file, but fires no exceptions 

Does ImageIO.write() not work for gifs? is this some sort of throwback to gif being a proprietary Compuserve thing? Or am I just being stupid (I’m guessing it’s the last one 🙂 )

Note that GIF can only store 256 colors.
