Can I use Beyond Compare on Windows 7 command line (cmd or Cygwin) to compare 2 images' content (their file format could vary, so I can't use a byte comparison) in a batch file?
If so, how do I interpret the Errorlevel codes returned? These are what I found so far:
1: Files are byte-identical. 2: Files are look identical but one is an indexed PNG and the other a Truecolor one. 13: Files are different. 100: File doesn't exist.
I can't find any reference on Scooter Software's website or on Help.
Is it possible to set a tolerance (as in the interactive tool) e.g. to ignore minor differences?
