box[/qualifiers]
A box shaped region is selected using the cursor. The results of the selection are written to a region file. This file has by default the same name as the image file, with the extension .reg.
A region filename can be specified using the /file= qualifier. The regions are by default inclusive. The /exclusive qualifier will create an exclusive region. Each new region selection is added to the region file, unless the /new qualifier is given. This applies to all region selections, including circle. The coordinates written to the file are in the original unbinned pixels, even if the image has been rebinned.
The define region will be excluded.
Specify the name of the region file. Otherwise the default will be the imagename.reg
Start a new region definition. If /new is not specified, then regions will be added to the existing file.
Draw the contents of a region file on the current image
Examples:
box ! select a box region using default region ! filename box/display/region=hello.reg ! draw the contents of the region file hello.reg
