PIX-PNG(1)			    BRL-CAD			    PIX-PNG(1)

NAME
       pix-png - convert a BRL-CAD PIX format image to a PNG format image

SYNOPSIS
       pix-png [-a] [-ggamma] [-ssquaresize] [-wfile_width] [-nfile_height]
	       [-oPNG_file] [PIX_file] [_PNG_file]

DESCRIPTION
       pix-png converts	a BRL PIX(5) format file to a PNG (Portable Network
       Graphics) format	file on	the standard output. The PNG file created will
       be an RGB file with a bit-depth of 8 and	a file gamma of	1.0.

       PIX image files do not contain information about	their size. The	size
       of the input PIX	image file must	be specified if	the dimensions are not
       the default 512x512 size.

OPTIONS
       -a
	   autosize the	input file to determine	file image height and width

       -g gamma
	   sets	the specified gamma correction value into the created PNG
	   file. A value of 0.6	is a close approximation of PC display
	   monitors. A negative	gamma value disables writing a gAMA chunk out
	   entirely (and is the	default).

       -s squaresize
	   sets	both the width and the height for the input to be squaresize

       -w file_width
	   tells pix-png that the input	is file_width pixels wide

       -n file_height
	   tells pix-png that the input	is file_height scanlines tall

       -o PNG_file
	   tells pix-png to write image	data to	the specified PNG_file output
	   file. The pix-png command will not write out	binary image data
	   directly to a terminal device as a safeguard.
