NAME

pixcrop - crop color pix files

SYNOPSIS

pixcrop in.pix out.pix

pixcrop in.pix out.pix inwidth outwidth outheight ulx uly urx ury lrx lry llx lly

DESCRIPTION

pixcrop crops any quadrilateral out of an arbitrarily large pix(5) input file (in.pix), squares that region to a given height and width output size, and writes the result to out.pix. The first form of pixcrop prompts for all parameters it needs to do the cropping. All responses should be pixel counts or first quadrant coordinates. The second form allows all of the needed parameters to be given on the command line and is intended for use from shell scripts. The coordinate names (the eight arguments listed above after outheight) refer to the input file, and more specifically to upper-left-x (ulx), lower-right-y (lry), etc., in clockwise-from-upper-left order.

The nearest input pixel is selected for each output pixel. No interpolation is done by this program.
