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.
