Frequently asked questions
What do zero crop dimensions mean?
A crop width or height of 0 uses the remaining pixels from the specified left or top edge to the corresponding image boundary.
How do crop settings work for a batch?
The same pixel rectangle is applied to each image. If it extends beyond any source boundary, processing reports an error; group similarly sized sources.
