Author: Diego Elio Pettenò <[email protected]> Committer: Luca Barbato <[email protected]> Date: Sat Aug 9 14:19:45 2014 +0100 tiff: Improve grayscale support Only use PAL8 if palette is present, else use GRAY8 for pixfmt. Instead of simulating a grayscale palette, use real grayscale pixels, if no palette is actually defined.
