|
|
|
|
- Draw a histogram of a PNM image:
|
|
|
|
`pnmhistmap {{path/to/input.pnm}} > {{path/to/output.pnm}}`
|
|
|
|
- Draw the histogram as dots instead of bars:
|
|
|
|
`pnmhistmap {{[-d|-dots]}} {{path/to/input.pnm}} > {{path/to/output.pnm}}`
|
|
|
|
- Specify the range of intensity values to include:
|
|
|
|
`pnmhistmap {{[-l|-lval]}} {{minval}} {{[-rv|-rval]}} {{maxval}} {{path/to/input.pnm}} > {{path/to/output.pnm}}`
