DESCRIPTION

17       im_stretch3()  stretches  the  input image by 3% horizontally, and dis‐
18       places it by xdisp/ydisp. It  uses  bi-cubic  interpolation,  but  runs
19       quickly. It works only for unsigned short images.

21       This  function  is part of the MARC acquisition software, but is gener‐
22       ally useful for squaring up the pixels in images from the Kontron  Pro‐
23       gRes camera range.
