# pamcut
|
|
|
|
> Cut out a rectangular region from a Netpbm image.
|
|
> See also: `pamcrop`, `pamdice`, `pamcomp`.
|
|
> More information: <https://netpbm.sourceforge.net/doc/pamcut.html>.
|
|
|
|
- Discard the specified number of columns/rows on each side of the image:
|
|
|
|
`pamcut -cropleft {{value}} -cropright {{value}} -croptop {{value}} -cropbottom {{value}} {{path/to/image.ppm}} > {{path/to/output.ppm}}`
|
|
|
|
- Keep only the columns between the specified columns (inclusively):
|
|
|
|
`pamcut -left {{value}} -right {{value}} {{path/to/image.ppm}} > {{path/to/output.ppm}}`
|
|
|
|
- Fill missing areas with black pixels if the specified rectangle does not entirely lie within the input image:
|
|
|
|
`pamcut -top {{value}} -bottom {{value}} -pad {{path/to/image.ppm}} > {{path/to/output.ppm}}`
