note 117410 added to function.imagetruecolortopalette

This function could be used to compress images. . . so one thought. When size is a concern, no-one needs 16,777,216 colors. Really, one could get away with 100,000 colors without loss of quality. This is where this function is lacking. The third parameter--number of colors--only takes effect below 256, which appears to be in accordance to the GIF format. Unfortunately, you can't tell the image to use "100,000" colors, instead it renders 256--the max. This should be bugfixed. Instead, this method will do some of the payload (30% off a PNG) and retains basically full color: <?php $palette = ImageCreate($width, $height); //no true-color ImageCopy($palette, $truecolor, 0, 0, 0, 0, $width, $height); ?> Hopefully this gets fixed in the future.
