*imcopy* - Compress an image and extract a small region

Note that, in one operation, it is possible to both compress an image and extract a small part of the compressed image.

  im> imcopy ``xdata$rp110590.qp[block=10][683:702,929:948]'' rp90_ac.imh

The coordinates used are the compressed or blocked coordinates, i.e. 6830/10=683, etc.


To limit the range of pulse heights included, the first square brackets should contain e.g. [block=10,pi=7:21].
