DECIMATE(1)

NAME
decimate - Reduce image or data file of MxN tuples to one of size IxJ

SYNOPSIS
decimate nbytes/pixel width height [outwidth outheight]

DESCRIPTION
decimate reads a file of width by height data items (each of which may be of arbitrary size as given by nbytes/pixel ), and discards enough of them to result in an output file of outwidth by outheight items, both of which default to 512. If the input image size is not an integer multiple of the output image size, then the decimated result will be padded with zero elements (pixels) on the right and top to achieve an output image of exactly the specified size.

To process a bw(5) format file, use a value of 1 for nbytes/pixel. To process a pix(5) format file, use a value of 3 for nbytes/pixel.
