geomatch(1)
Check whether the geometries (e.g., grid dimensions, pixel sizes, spatial coordinates) or two or more images match.
SYNOPSIS
geomatch ImagePaths
DESCRIPTION
This tool reads two or more images and tests whether their grid dimensions, pixel sizes, and image-to-space transformations match. Optionally, all images are reoriented into standard orientation before performing the test. If all images match, the tool returns with exit code 0, otherwise it returns with exit code 2. In case of an error (e.g., one of the images can not be read), the exit code is 1.
