NAME
       pix - Color RGB image file format and utilities

FORMAT
       A pix file contains sequences of	pixels.	Each pixel is stored as	three
       unsigned	chars, first red, then green, then blue. The intensity of each
       color ranges from 0 ("off") to 255 ("on"). The first pixel in a pix
       file is the lower left corner of	the image. The pixels proceed from
       left-to-right across each scanline, with	scanlines being	written	from
       the bottom to the top of	the image.

       By convention, pix images are usually square, and thus their dimensions
       can be determined by the	file size. If this is not the case, often only
       the file	width need be known by a program reading the file. History has
       left us with two	"standard" sizes, 512x512 and the "higher" 1024x1024.
       A common	practice for other file	sizes is to include the	file width in
       the filename.

       At some time in the future pix files will probably get self-typing
       headers so that parameters such as their	size can be automatically
       determined by programs.

UTILITIES
       pix-fb display a	.pix format image on a framebuffer.

       fb-pix produce a	.pix file from a framebuffer image.

       pix-bw convert a	.pix file to a black and white .bw file.

       bw-pix convert a	black and white	.bw file to a .pix file.

       ap-pix convert an Applicon Color	Plotter	file to	a .pix file.

       pixtile combine several small .pix files	into one large one.

       pixstat gives statistics	concerning a .pix file.

       pixhist displays	a color	histogram on a framebuffer.

       pixhist3d display three views of	an RGB color space histogram on	a
       framebuffer.

       pixhist3d-pl unix plot of RGB color space utilization.

       pixdiff shows which pixels/colors differ	between	two .pix files.

       pixrect extracts	an arbitrary rectangle from a .pix file.

       pixrot rotate, reverse, or invert a .pix	file.

       pixscale	scale a	.pix file up or	down.

       pixfilter a collection of 3x3 kernel filters for	.pix files.

       bw3-pix merges three .bw	files into one .pix file.

       pix-bw3 separates .pix file RGB colors into three .bw files.
