These operations modify the input image. You can't easily use them in pipelines, but they are useful for paintbox-style programs.
int im_insertplace (IMAGE *main, IMAGE *sub, int x, int y);
Copy sub
into main
at position x
, y
. The two images must match in
format, bands and coding.
This an inplace operation, so main
is changed. It does not thread and will
not work well as part of a pipeline.
See also: im_insert()
