MERGECHAN(1)		    General Commands Manual		  MERGECHAN(1)

NAME
       mergechan  - merge channels from	several	RLE files into a single	output
       stream

SYNOPSIS
       mergechan [ -a ]	[ -o outfile ] infiles ...

DESCRIPTION
       Mergechan takes input from several RLE files and	combines them  into  a
       single output stream.  Each channel in the output stream	comes from the
       respective filename specified on	the input (i.e., channel zero is taken
       from  the  first	 file, channel one from	the next, etc).	 The same file
       can be specified	more than once.	 If the	-a flag	is given, the channels
       are  numbered  from -1 (the alpha channel) instead of zero.  All	of the
       input channels must have	exactly	the same dimensions  (use  crop(1)  to
       adjust files to fit each	other).

       Mergechan  is  typically	 used  to introduce an alpha mask from another
       source into an image, or	 combine  color	 channels  digitized  indepen-
       dently.

       If -o is	specified, the output will be written to outfile.

SEE ALSO
       crop(1),	rleswap(1), urt(1), RLE(5).

       John W. Peterson, University of Utah.

BUGS
       Mergechan is totally ignorant of	the color maps of the input files.

       The restriction that all	input files must be the	same size could	proba-
       bly be removed.
