NAME

       pfsoctavergb - Process red, green and blue channels in pfs stream using Octave

SYNOPSIS

       pfsoctavergb <octave_program>

DESCRIPTION

       Use  this  command  to execute a GNU Octave program on red, green and blue channels of each frame in the pfs stream. octave_program must be
       given in quotation marks ("") and must not produce any output (it can output to stderr, not to stdout). Red, green and blue color  channels
       are available in octave_program as R, G and B matrices.

       Note: This command requires GNU Octave.

EXAMPLES

       pfsinrgbe frames_%04d.hdr | pfsoctavergb "R = R.^2; G = G.^2; B = B.^2;" | pfsview

       Expand the dynamic range of a sequence of frames and show the result with pfsview.

NAME

       pfsinmulti - read several streams of frames and write pfs streams to named pipes

SYNOPSIS

       pfsinmulti pfsinmulti <file> [--frames f:s:t] [--skip-frames] [<file>...] -- command @1 @2 [@3 ...]

DESCRIPTION

       Use  this  command  to read several animation sequences and write them to pfsstreams. This command is useful with those pfs programs, which
       take several pfs streams as arguments. For example, the following command can be used to combine two animations so that there are  stitched
       together:

	 pfsinmulti anim_a-%04d.hdr anim_b-%04d.hdr -- pfscat @1 @2

       arguments  @1 and @2 are replaced with named pipes for anim_a-%04d.hdr and anim_b-%04d.hdr frames respectively. command argument is obliga-
       tory and it must be preceded with '--'. There should be as many @1, @2, .., @n arguments as there are animation sequences given as input.

       Arguments --frames, --skip-frames and other options are handled the same way as in pfsin program. Also pfsinmulti recognizes the same  file
       formats as pfsin.

       Technically,  pfsinmulti creates a named pipe for each pfsstream, replaces @n arguments with the names of those pipes and deletes the pipes
       when command finishes.

EXAMPLES

       pfsinmulti image1.hdr image2.hdr -- cat @1 @2 | pfsview

	      Does the same as 'pfsv image1.hdr image2.hdr' but in much more sophisticated way.

SEE ALSO

       pfsin(1)

BUGS

       This command currently does not handle multiple frames given with a %d pattern in case of LDR formats: JPEG, PNG, PNM.
