7.1.437. images_equal
Link to classic view
Usage: images_equal [-all] fileA fileB
- Simple program to test if 2 2D images are identical.
- Exit status is 1 if they are equal, and 0 if they are not.
- If either image cannot be read, then exit status also 0.
- If the ‘-all’ option is used, then all the images in the files
are compared, and all must be equal for the exit status to be 1.
- If ‘-all’ is NOT given, only the first image in each file is
compared.
- This program is meant for use in scripts that deal with DICOM
servers that sometimes deal out multiple copies of the same
image in different filenames :-(
- Also see program uniq_images, which works on multiple inputs.
