pbmmask

Create a mask bitmap from a regular bitmap. See also: pambackground. More information: https://netpbm.sourceforge.net/doc/pbmmask.html.

  • Create a mask bitmap separating background from foreground:

pbmmask {{path/to/image.pbm}} > {{path/to/output.pbm}}

  • Expand the generated mask by one pixel:

pbmmask -expand {{path/to/image.pbm}} > {{path/to/output.pbm}}
