- 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:
