As I wrote the patch a while ago i have to support :-)

works for me with IM, good quality. - +1 after testing

I used my patched file all the time and copied to typo3-installations but 
forgot it the last months, so i'm glad that you bring it up again.

btw - that remembers me to write a patch to enable cropscale in IMG/Text and 
IMAGE in BE. The fields are evaluated to integer so there is no chance to 
enter 100c or 100c-50 for cropscale
