--- Comment #4 from Brion Vibber <[email protected]> 2011-07-01 00:26:01 UTC --- Ok I did a quick check resizing these versions of the Ping_deny.png image: a.png -- the truecolor version b.png -- the grayscale version (it is in fact grayscale, not indexed!) truecolor.png -- a version explicitly re-saved from Gimp from a.png gray.png -- a version explicitly converted to grayscale in Gimp from a.png indexed.png -- a version explicitly converted to indexed color in Gimp from a.png for x in a.png b.png gray.png indexed.png truecolor.png do convert \ -quality 95 \ -background white \ $x \ -thumbnail 300x142\! \ -depth 8 -auto-orient \ 300px-$x done The resulting images match what I see from the above-linked thumbs: * truecolor image, scaled, is still truecolor. * grayscale image, scaled, is still grayscale. Looks slightly darker and possibly blurrier than scaled version of truecolor image. * indexed-color image, scaled, becomes truecolor. Looks identical to grayscale version. So the commands we're giving are exactly the same; ImageMagick itself is applying some slightly different behavior.
