  • Generate a rectangular greyscale map:

pgmtexture -rectangle > {{path/to/output.pgm}}

  • Generate a elliptical greyscale map:

pgmtexture -ellipse {{path/to/image.pgm}} > {{path/to/output.pgm}}

  • Generate a greyscale map from the top-left corner to the bottom-right corner:

pgmtexture -diagonal {{path/to/image.pgm}} > {{path/to/output.pgm}}
