|
- Add simulated shadows to a PPM image:
|
||
|
|
|
||
|
|
`ppmshadow {{path/to/input_file.ppm}} > {{path/to/output_file.ppm}}`
|
||
|
|
|
||
|
|
- [b]lur the image by the specified number of pixels:
|
||
|
|
|
||
|
|
`ppmshadow -b {{n}} {{path/to/input_file.ppm}} > {{path/to/output_file.ppm}}`
|
||
|
|
|
||
|
|
- Specify the displacement of the simulated light source to the left and the top of the image:
|
||
|
|
|
||
|
|
`ppmshadow -x {{left_offset}} -y {{top_offset}} {{path/to/input_file.ppm}} > {{path/to/output_file.ppm}}`
