pfsinpfm(1) General Commands Manual pfsinpfm(1)NAME
pfsinpfm - Load images or frames in PFM format
SYNOPSIS
pfsinpfm (<file> [--frames <range>] [--skip-missing]) [<file>...]
DESCRIPTION
Use this command to read 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). The frames are converted to pfs stream and send to the Standard Output. This command can
handle both color and gray-scale images.
Details on the format of the pattern file names, which are used for reading multiple frames, can be found in the manual page of pfsinppm.
To automatically recognize a file format from the extension, use pfsin command instead.
EXAMPLES
pfsin memorial.pfm | pfsout memorial.hdr
Converts from one HDR format to another
BUGS
pfsinpfm does not handle images that store floating point numbers using big-endian format. pfsoutpfm may also read floating point numbers
incorrectly on big-endian machines.
