byte and rgb images
  • Upsamples the input 2D image by a factor of n and

    writes result into output_image; n must be an integer in the range 2..30.

  • 7th order polynomial interpolation is used in each

    direction.

  • Inputs can be complex, float, short, PGM, PPM, or JPG.

  • If input_image is in color (PPM or JPG), output will

    be PPM unless output_image ends in ‘.jpg’.

  • If output_image is ‘-‘, the result will be written

    to stdout (so you could pipe it into something else).

  • The ‘-A’ option means to write the result in ASCII

    format: all the numbers for the file are output, and nothing else (no header info).
