pfsoutpfm(1) General Commands Manual pfsoutpfm(1)NAME
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
NetPBM package (pamtopfm and pfmtopam commands). Source pfs frames should be piped to the Standard Input. This command can handle both
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.
SEE ALSO pfsout(1)pfsoutppm(1)pfsinpfm(1)BUGS
pfsoutpfm may store floating point numbers incorrectly on big-endian machines.
