int im_stretch3( in, out, xdisp, ydisp )
IMAGE *in, *out;
double xdisp, ydisp;
DESCRIPTION
im_stretch3() stretches the input image by 3% horizontally, and dis-
places it by xdisp/ydisp. It uses bi-cubic interpolation, but runs
quickly. It works only for unsigned short images.
This function is part of the MARC acquisition software, but is gener-
ally useful for squaring up the pixels in images from the Kontron Pro-
gRes camera range.
RETURN VALUE
The function returns 0 on success and -1 on error.
