Up: Image Processing Tasks
Extracts a subset of an input image. The output image can be larger than
the subset; in this case the additional pixels are blanked if the output
image is being created, unmodified if it already exists. It works on
images of any dimensions, and any subset of the input image can be
placed anywhere in the output image.
This task can also be used to build a N+P dimensional image from a set
of N dimensional ones, by initializing the output image once with its
full dimensions and then placing the (subset of the) input images at the
appropriate place in the output image.
