this package has a Provides:imagemagick, but it doesn't ship a /usr/bin/compare like imagemagick does; therefore, it's not a full alternative to it.
GraphicsMagick does provide a 'compare' command which offers some operation modes similar to ImageMagick's compare (-colorspace, -debug, -define, -density, -depth, -highlight-color, -interlace, -limit, -metric, -monitor, -sampling-factor, -size, -type, -verbose) although it was never designed to be an exact replacement and is not derived from the ImageMagick version since it was implemented after the fork based on my own imagination. From looking at the GraphicsMagick Makefile, it appears that does install a 'compare' command so the lack of 'compare' must be an artifact of Debian packaging.
If the Debian packaging was updated to include 'compare' would this satisfy your expectations?
That said, installing commands with generic names like 'convert' and 'compare' has always seemed problematic to me since it could conflict with other software.
