NAME
       pambayer - interpret Bayer patterns

SYNOPSIS
       pambayer -type={1|2|3|4} [pamfile]

       Minimum	unique	abbreviation of option is acceptable.  You may use double hyphens instead
       of single hyphen to denote options.  You may use white space in place of the  equals  sign
       to separate an option name from its value.

DESCRIPTION
       This program is part of Netpbm(1)

       pambayer  reads a Bayer pattern in a 1-deep Netpbm image and produces a color image in PAM
       RGB format as output.

       A Bayer pattern is what you get from the optical sensor in some digital cameras.   Such	a
       camera  doesn't have a red, green, and blue sensor in the exact same place for an individ-
       ual pixel.  Instead, it has red, green, and blue sensors laid out  in  a  two  dimensional
       array.	The  pattern  in which they are laid out is the Bayer pattern.	The input to pam-
       bayer is one sample value for each of those sensors, so some samples  are  red,	some  are
       green, and some are blue.

       The  input  image  is a PNM image or PAM image of arbitrary tuple type.	pambayer looks at
       only the first plane of the input.

       The output image is a PAM image of tuple type 'RGB', i.e.  a standard  color  image.   You
       can convert this to PPM with pamtopnm(1)

       If  you're  interested  in just one of the primary colors, use pamchannel on the output of
       pambayer to extract it.

OPTIONS
       type=n This tells which Bayer pattern the input is:

       1      GBG/RGR/GBG matrix

       2      RGR/GBG/RGR matrix

       3      BGB/GRG/BGB matrix

       4      GRG/BGB/GRG matrix

	      This option is mandatory.
