Auto-cropping seems to work great for large datasets except for two limitations:
1) It detects one color only. For example, scanning negative film strips may produce black border between frames and white borders along perforation. Only white borders are removed even is detection is done more than once on the same frame (i.e. nothing is cropped on the second pass). Ideally choice may include "white, black, white and black" options.
2) Is it possible to add an offset to auto-detected borders? For example positive (out) or negative (in) offset from the detected border expressed in pixels or image %.
Both features could be useful in batch dialog, command line, and in one-by-one processing.
Many thanks!
