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.
