# ppmchange
|
|
|
|
> Change all pixels of one color in a PPM image to another color.
|
|
> More information: <https://netpbm.sourceforge.net/doc/ppmchange.html>.
|
|
|
|
- Exchange the first color in each `oldcolor` - `newcolor` pair with the second color:
|
|
|
|
`ppmchange {{oldcolor1 newcolor1 oldcolor2 newcolor2 ...}} {{path/to/input.ppm}} > {{path/to/output.ppm}}`
|
|
|
|
- Specify how similar colors must be in order to be considered the same:
|
|
|
|
`ppmchange -closeness {{percentage}} {{oldcolor1 newcolor1 oldcolor2 newcolor2 ...}} {{path/to/input.ppm}} > {{path/to/output.ppm}}`
|
|
|
|
- Replace all pixels not specified in the arguments by a color:
|
|
|
|
`ppmchange -remainder {{color}} {{oldcolor1 newcolor1 oldcolor2 newcolor2 ...}} {{path/to/input.ppm}} > {{path/to/output.ppm}}`
