Feature request: Auto-crop image
Posted: Tue Mar 17, 2015 8:23 pm
The only reason I still have IrfanView installed (therefore limited to win32 sandbox)…
I can think of two possible extension options:
- trim from selected frames only (top, bottom, left, right)
- trim when pattern changes (rather than detecting first if pixels adjacent to the frame have the same color and then detecting how wide the same area towards the centre is - this would be detecting just the break in the pattern so therefore could support multiple different colors initially adjacent to the frame. For instance, image:would result in:
when crop from top only.
and in:when crop from all directions.
whereas default trim (like in IrfanView) would result in:
(just left & right as those had one a same R-color adjacent to the frame initally)
