# pbmreduce
|
|
|
|
> Proportionally reduce a PBM image.
|
|
> See also: `pamenlarge`, `pamditherbw`.

> More information: <https://netpbm.sourceforge.net/doc/pbmreduce.html>.
|
|
|
|
- Reduce the specified image by the specified factor:
|
|
|
|
`pbmreduce {{n}} {{path/to/image.pbm}} > {{path/to/output.pbm}}`
|
|
|
|
- Use simple thresholding when reducing:
|
|
|
|
`pbmreduce {{[-t|-threshold]}} {{n}} {{path/to/image.pbm}} > {{path/to/output.pbm}}`
|
|
|
|
- Use the specified threshold for all quantizations:
|
|
|
|
`pbmreduce {{[-va|-value]}} {{0.6}} {{n}} {{path/to/image.pbm}} > {{path/to/output.pbm}}`
