pnmpaste

pnmpaste - paste a rectangle into a portable anymap

pnmpaste [-replace|-or|-and |-xor] frompnmfile x y [intopnmfile]

Reads two portable anymaps as input. Inserts the first anymap into the second at the specified location, and produces a portable anymap the same size as the second as output. If the second anymap is not specified, it is read from stdin. The x and y can be negative, in which case they are interpreted relative to the right and bottom of the anymap, respectively.

This tool is most useful in combination with pnmcut. For instance, if you want to edit a small segment of a large image, and your image editor cannot edit the large image, you can cut out the segment you are interested in, edit it, and then paste it back in.

Another useful companion tool is pbmmask.

The optional flag specifies the operation to use when doing the paste. The default is -replace. The other, logical operations are only allowed if both input images are bitmaps. These operations act as if white is TRUE and black is FALSE.

All flags can be abbreviated to their shortest unique prefix.
