Trouble with unwanted offset
Posted: 2014-07-24T09:09:07-07:00
Hi there!
I'm trying to convert an image in a few steps.
It starts off as a 580x480 image and I only need 474x474 of those pixels.
So it goes from the original image, then it gets converted with a 474x474 circular mask (so now only the pixels inside of the circle are visible).
After that, I remove some colours from the image.
I'm certain the step that causes the offsetting is the mask.
Here's my steps:
convert ORIGINAL.gif \
MASK.png \
-alpha Off \
-compose CopyOpacity \
-composite \
-trim \
OUT.png
Does anyone have any suggestions to achieve the same result without offsets? (I'm getting a 3, 3 offset.)
