NAME
imshift - shifts the pixels in an image
SYNOPSIS
imshift file [dr=] [dc=] [fill=]
DESCRIPTION
Shifts each pixel value in the given file by dr rows and/or dc
columns. Any pixels shifted out of the image are discarded, and vacated
pixels are set to zero or the value set by the fill
keyword.
If the pixel shift in either rows or columns differs from an integer by more
than .001, the program uses a bi-linear interpolation
algorithm.
EXAMPLE
imshift m13 dr=10.3 dc=-5
SEE ALSO
rotate,
flip
BUGS
Nothing is done to the header to indicate that the image has been
shifted.
