I’m using “compare” to check differences between two bitonal (bi-level) BMP files.
ie., one bit per pixel. The files are identical except for a few bytes in the header. (Verified using a hex editor, and with the DOS “fc” command). Even so, the compare command yields a distinctively non-blank output image – It looks like a faint, washed-out copy of the original. I’ve tried these options: -depth 1 -type Bilevel …. to no avail. Is this normal behavior? It sure doesn’t seem right to me, but I’m rather a newbie at ImageMagick. Why does “compare” produce an RGB output file when comparing two bitonal input files? How did the output get to be shades-of-gray, when the input is bitonal? Rafe Bustin -- No virus found in this outgoing message. Checked by AVG Free Edition.
