The following command worked with version 6.4.0 but not 6.4.1 (this is on Mac OS X, installed via Macports):
Code: Select all
mogrify -rotate 90 -crop 855x690+50+15! -type TrueColorMatte -transparent "#EFEFEF" -depth 8 orig.png
The original image (orig.png):
--------------------------
Original image processed with version: ImageMagick 6.4.0 04/04/08 Q16 (this is expected behavior):
--------------------------
Original image processed with version: ImageMagick 6.4.1 06/05/08 Q16 (Hm, something changed):
Thanks for any help!

For the record, I switched the order of crop and rotate:
Code: Select all
mogrify -crop 690x855+15+50! -rotate 90 -type TrueColorMatte -transparent "#EFEFEF" -depth 8 orig.png
Just wish I knew why it changed...

The order of operations in "mogrify" is not defined as it is use a older IM v5 legacy command line handling, that 'saves up' the operations to be applied.
You are better off using "covert", which like "mogify" can save back to the original image file. It just can only handle one image at a time.
Code: Select all
convert orig.png -crop 690x855+15+50! -rotate 90 -transparent "#EFEFEF" -depth 8 orig.png
Convert will always try to do all commands in the order given!
