PIXINTERP2X(1)			    BRL-CAD			PIXINTERP2X(1)

NAME
       pixinterp2x - interpolate a color pix file twice	as large as the
       original

SYNOPSIS
       pixinterp2x [-h]	[-s squarefilesize] [-w	file_width] [-n	file_height]
		   [infile.pix]	_ outfile.pix

DESCRIPTION
       Pixinterp2x does	a bilinear interpolation between the pixels of the
       input pix(5) file to create the output file. This program is most
       useful when creating images for photographing. Even though no
       additional image	information is created,	there may be significant
       photographic advantages to operating the	display	at its highest
       resolution.

       This is a very fast implementation of one special case of
       interpolation; the general tool for interpolation is pixscale(1).

       -h
	   "hires" flag. Set both the height and width of the input to 1024.
	   The default is 512x512.

       -w file_width
	   Specify the width (in pixels) of the	scanlines in the input file.
	   The default is 512.

       -n file_height
	   Specify the number of scanlines of input to be processed. The
	   default is 512.

       -s squarefilesize
	   Specify both	the number of pixels per scanline and the number of
	   scanlines in	the file to process.

       The interpolated	scanlines fall exactly half way	between	the input
       lines, and the input lines are exactly preserved. Rather	than
       extrapolate beyond the edges of the file, the first X and Y line	is
       duplicated (left	and bottom edge). This differs from the	behavior of
       pixscale(1).

BUGS
       More memory is used than	is strictly necessary.
