|
|
|
|
> Proportionally reduce a PBM image.

|
|
|
- Reduce the specified image by the specified factor:
|
|
|
|
`pbmreduce {{N}} {{path/to/image.pbm}} > {{path/to/output.pbm}}`
|
|
|
|
- Use simple thresholding when reducing:
|
|
|
|
`pbmreduce -threshold {{N}} {{path/to/image.pbm}} > {{path/to/output.pbm}}`
|
|
|
|
- Use the specified threshold for all quantizations:
|
|
|
|
`pbmreduce -value {{0.6}} {{N}} {{path/to/image.pbm}} > {{path/to/output.pbm}}`
