> Apply antialiasing onto a PNM image.

> More information: <https://netpbm.sourceforge.net/doc/pnmalias.html>.
|
|
|
|
- Perform antialiasing on a PNM image, taking black pixels as background and white pixels as foreground:
|
|
|
|
`pnmalias {{path/to/input.pnm}} > {{path/to/output.ppm}}`
|
|
|
|
- Explicitly specify the background and foreground color:
|
|
|
|
`pnmalias -bcolor {{background_color}} -fcolor {{foreground_color}} {{path/to/input.pnm}} > {{path/to/output.ppm}}`
|
|
|
|
- Apply altialiasing to foreground pixels only:
|
|
|
|
`pnmalias {{[-fo|-fonly]}} {{path/to/input.pnm}} > {{path/to/output.ppm}}`
|
|
|
|
- Apply antialiasing to all surrounding pixels of background pixels:
|
|
|
|
`pnmalias {{[-ba|-balias]}} {{path/to/input.pnm}} > {{path/to/output.ppm}}`
