PIXRECT

## Name

pixrect — extract a rectangle from a color pix file

## Synopsis

`pixrect` [-s `squaresize`] [-w `width`] [-n `height`] [-S `out_squaresize`] [-W `out_width`] [-N `out_height`] [-x `xorig`] [-y `yorig`] [-o `out_file.pix`] `file.pix` > [`out_file.pix`]

## DESCRIPTION

pixrect extracts a rectangular region from a colored pix(5) format file. The default input image size is 512x512. The x,y coordinates of the origin (the default xorig=0, yorig=0 corresponds to the lower left corner) are passed as command line arguments.

The `-w` `file_width` flag specifies the width of each scanline in the input file, in pixels. `-W` `scr_width` does the same for the display device.

The `-n` `file_height` and `-N` `scr_height` flags specifies the height in scanlines of the input file or display device respectively.

`-s` `squarefilesize` and `-S` `squarescrsize` set both the height and width to the size given (for input file and display device respectively).

`-o` `out_file.pix` is a way of specifying output file name.

This utility supports redirected input/output images.
