Hello, All,
Running ImageMagick 6.4.0-Q16 on Windows XP & ImageMagick 6.2.8-Q16 on Fedora Core 6.
Ran 'compare' on 2 TIFF images on both systems, results in XP are different than results in Linux.
Windows command line: compare -metric MAE image105.tif imgcomp.tif null:
RESULTS: 2439.81 (0.0372291)
Linux command line: compare -metric MAE image105.tif imgcomp.tif null:
RESULTS 3253.08 db
I realize that the format of the output is different, my concern is with the number. Why 2439 in Windows and 3253 in Linux? Files were initially dnlded to Windows then copied via pscp to Linux. No other changes were made. The 2439 number in Windows is what I would expect, the images are nearly identical. Any advice on this would be greatly appreciated.
Thanx.

We suspect a patch was applied after ImageMagick 6.2.8 was released. Download / install ImageMagick 6.4.0 on your Linux box and report it as a bug if the MAE is not identical.

Dnlded and installed 6.4.0 on Linux, compare results now identical to result in Windows.
Excellent! Thanx very much for your timely and accurate assistance.
