WINDOW: Window (Crop) an Image to a Smaller Size

WINDOW is used to trim (or ``crop'') an image or spectrum within a specified ``window''. The image in the 'source' buffer is replaced by the region enclosed within pre-defined BOX `n'. If the specified box extends beyond the edges of the image, WINDOW will do nothing. See BOX for defining regions of interest (boxes).

Example: Let image 7 have rows numbered 0-500 and columns numbered 0-500. We want to chop out a 100 by 100 image, with the first row of the new image at 100, and the first column at 200.
