`ppmfade -f {{path/to/image1.ppm}} -l {{path/to/image2.ppm}} -{{mix|spread|shift|relief|oil|...}}`

- Generate a transition starting with the specified image and ending in a solid black image:

`ppmfade -f {{path/to/image.ppm}} -{{mix|spread|shift|relief|oil|...}}`

- Generate a transition starting with a solid black image and ending with the specified image:

`ppmfade -l {{path/to/image.ppm}} -{{mix|spread|shift|relief|oil|...}}`

- Store the resulting images in files named `base.NNNN.ppm` where `NNNN` is a increasing number:

`ppmfade -f {{path/to/image1.ppm}} -l {{path/to/image2.ppm}} -{{mix|spread|shift|relief|oil|...}} -base {{base}}`
