# pnmrotate
|
|
|
|
> Rotate a PNM image.
|
|
> More information: <https://netpbm.sourceforge.net/doc/pnmrotate.html>.
|
|
|
|
- Rotate a PNM image by some angle (measured in degrees, counter-clockwise):
|
|
|
|
`pnmrotate {{angle}} {{path/to/input.pnm}} > {{path/to/output.pnm}}`
|
|
|
|
- Specify the background color exposed by rotating the input image:
|
|
|
|
`pnmrotate -background {{color}} {{angle}} {{path/to/input.pnm}} > {{path/to/output.pnm}}`
|
|
|
|
- Disable anti-aliasing, improving performance but decreasing quality:
|
|
|
|
`pnmrotate -noantialias {{angle}} {{path/to/input.pnm}} > {{path/to/output.pnm}}`
