Automator has some very handy image scale/crop/rotate actions that appear to be driven by Preview.app. Does anybody know how to globally change the default compression that is used during these operations, particularly with respect to jpeg images?
By comparing compression results with those of identical operations in Photoshop, it appears that Preview.app is scaling with a quality of approximately 70-80%. It would be nice to be able to specify and/or change this in Preview.app.
Thanks!
