- Scale an image such that the result has the specified dimensions:

`pnmscalefixed {{[-w|-width]}} {{width}} {{[-h|-height]}} {{height}} {{path/to/input.pnm}} > {{path/to/output.pnm}}`

- Scale an image such that the result has the specified width, keeping the aspect ratio:

`pnmscalefixed {{[-w|-width]}} {{width}} {{path/to/input.pnm}} > {{path/to/output.pnm}}`

- Scale an image such that its width and height is changed by the specified factors:

`pnmscalefixed {{[-xsc|-xscale]}} {{x_factor}} {{[-ysc|-yscale]}} {{y_factor}} {{path/to/input.pnm}} > {{path/to/output.pnm}}`
