The following is the output from identify on the same test file:
Format: GIF (CompuServe graphics interchange format)
Alpha: (255,255,255,255) #FFFFFFFF
Background color: #FFFFFFFF
Border color: #DFDFDF00
Matte color: grey74
Transparent color: none
Version: ImageMagick 6.2.9 08/21/06 Q8 http://www.imagemagick.org
It appears that the matteColor() function is returning the same value as in the identify Matte color, which is NOT a transparent color.
How do I get the value from the Alpha channel, (255,255,255,255) #FFFFFFFF?
I'd really appreciate some help with this.
