|
|
- Remove white borders on a PNM image:
|
|
|
|
`pnmcrop -white {{path/to/image.pnm}} > {{path/to/output.pnm}}`
|
|
|
|
- Remove borders of the specified color that are on the top and left side of the image:
|
|
|
|
`pnmcrop -bg-color {{color}} -top -left {{path/to/image.pnm}} > {{path/to/output.pnm}}`
|
|
|
|
- Determine the color of the borders to be removed by the color of the pixel in the specified corner:
|
|
|
|
`pnmcrop -bg-corner {{topleft|topright|bottomleft|bottomright}} {{path/to/image.pnm}} > {{path/to/output.pnm}}`
|
|
|
|
- Leave a border with a width of `n` pixels. Additionally, specify the behaviour if the image is entirely made out of background:
|
|
|
|
`pnmcrop -margins {{n}} -blank-image {{pass|minimize|maxcrop}} {{path/to/image.pnm}} > {{path/to/output.pnm}}`
