# pbmclean

> Clean up a PBM image by erasing isolated black and white pixels.
> More information: <https://netpbm.sourceforge.net/doc/pbmclean.html>.

- Clean up a PBM image by erasing isolated black and white pixels:

`pbmclean {{path/to/image.pbm}} > {{path/to/output.pbm}}`

- Clean up only black/white pixels:

`pbmclean -{{black|white}} {{path/to/image.pbm}} > {{path/to/output.pbm}}`

- Specify the minimum number of neighbouring pixels of the same color in order for a pixel not to be considered isolated:

`pbmclean {{[-m|-minneighbours]}} {{3}} {{path/to/image.pbm}} > {{path/to/output.pbm}}`
