pfsinmulti(1) read several streams of frames and write pfs streams to


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


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 obligatory 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.


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

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


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