pfsoutpfm - Write images or frames in OpenEXR format
SYNOPSIS
pfsoutpfm (<file> [--frames <range>]) [<file>...]
DESCRIPTION
Use this command to write frames in PFM format. PFM format is used for HDR Shop plug-ins and is also supported by some recent versions of

color (XYZ channels) and grayscale (Y channel) images.
Details on the format of the pattern file names, which are used for saving multiple frames, can be found in the manual page of pfsoutppm.
EXAMPLES
pfsin memorial.hdr | pfsoutpfm memorial.pfm
Converts from one HDR format to another
pfsin memorial.hdr | pfsextractchannels Y | pfsoutpfm memorial.pfm
Stores memorial image as a grayscale PFM file.

pfsoutpfm may store floating point numbers incorrectly on big-endian machines.
