  • Scale an image such that the result has the specified dimensions:
    pamscale -width width -height height path/to/input.pam > path/to/output.pam
  • Scale an image such that the result has the specified width, keeping the aspect ratio:
    pamscale -width width path/to/input.pam > path/to/output.pam
  • Scale an image such that its width and height is changed by the specified factors:
    pamscale -xscale x_factor -yscale y_factor path/to/input.pam > path/to/output.pam
  • Scale an image such that it fits into the specified bounding box while preserving its aspect ratio:
    pamscale -xyfit bbox_width bbox_height path/to/input.pam > path/to/output.pam
  • Scale an image such that it completely fills the specified box while preserving its aspect ratio:
    pamscale -xyfill box_width box_height path/to/input.pam > path/to/output.pam
