Hello People,
As part of our testing, we compare images using the 'compare' command of
'ImageMagick' like the following:
compare input.png output.png comp_result.png
The 'output' of this 'compare' command is another image ('comp_result.png' in
the above example). Now, in order to find out if the comparison was successful
or not, someone has to manually open the result file named 'comp_result.png'
and have a look at it.
Instead of this arrangment (someone manually opening the output file and
deciding 'Pass/Fail'), can 'ImageMagick' itself compare two images and give a
'0/1 result' based on which we can mark the 'comparsion' as 'Pass/Fail'?
The color code, '(216, 0, 27)', seems to be always present in the image drawn
in case of a 'Failed Comparison'. Can that error code be used to find out the
result (presence of (216, 0, 27) indicates a 'mismatch' and its absence
indicates a 'perfect match')?
Thanks for your time,
Vaidyalingam.
