2006.03.31 15:13 "tiff2rgba misbehavior?", by Bugs Bunny

this has been an issue for me for a while, but only now have i taken the 
time to write about it

everytime i use tiff2rgb -n on any file, be it rgb, rgba, cmyk, it seems to 
use the red value as the alpha value leaving everything pink

is this an endianness issue?

- i'm using a powerpc processor

is my system set up incorrectly?

- macosx 10.2

or something else and i'm just a noob?

attached are the input files and the resulting files from tiff2rgba -n

gradient-rgb.tiff is photometric rgb, 256 grays, and no alpha channel
gradient-rgba.tiff is photometric rgb, 256 grays, and an alpha channel
output-rgb.tiff and output-rgba.tiff are the resulting output from tiff2rgba 
-c none -n (they are the same)

any and all help is greatly appreciated
