pfsinrgbe(1)		    General Commands Manual		  pfsinrgbe(1)

NAME
       pfsinrgbe - Load	images or frames in Radiance RGBE format

SYNOPSIS
       pfsinrgbe   [--linear]  (<file>	[--frames  <range>]  [--skip-missing])
       [<file>...]

DESCRIPTION
       pfsinrgbe command loads images in Radiance RGBE format and  writes  pfs
       stream  to  the Standard	Output.	The pfs	stream is usually piped	to an-
       other program for further processing. To	detect	the  format  automati-
       cally based on the extension, use pfsin command.

       Since RGBE is an	HDR format, 'LUMINANCE'	tag is set to 'RELATIVE' (rel-
       ative linear luminance values).

       To read images from standard input use a	single	dash  '-'  instead  of
       filename. The images are	read until EOF is reached.

       Each  file  can	contain	 a %d pattern, which is	substituted with frame
       numbers.	The pattern has	the same syntax	as C printf command. For exam-
       ple, you	can use	%04d to	make the frame number four digit with proceed-
       ings zeros. You can select the frames using the following options  (the
       options must be always given after the file name):

       --frames	<range>
	      Range is given in	mathlab	/ octave format:

	      startframe:step:endframe

	      Frame  numbers  start with startframe (default 0), are increased
	      by step (default 1) and stop at endframe You  can	 skip  one  of
	      those  values, for example 1:100 for frames 1,2,...,100 and 0:2:
	      for frame	0,2,4,... up to	the last file that exists.

       --skip-missing
	      Skip up to ten frames in a row if	corresponding files are	 miss-
	      ing.  Otherwise  the program stops reading sequence at the first
	      file that	does not exists. This switch does  not	apply  to  the
	      first frame in a sequence. This switch can be useful if there is
	      a	rendered animation where some of the frame has not been	gener-
	      ated.

       --linear
	      Ignored for compatibility	with pfsinppm.

EXAMPLES
       pfsinrgbe intro%d.hdr frame%d.hdr | ...

	      Concatenate two animations into one and pass it to pipe for fur-
	      ther processing.

IMPORTANT NOTE
       There is	an incompatibility between viewers of RGBE format in terms  of
       absolute	 luminance values. The ximage viewer from Radiance package ex-
       pects radiance values in	RGBE files and uses  the  WHITE_EFFICACY  con-
       stant  equal  to	 179.0f	to convert from	radiance to luminance. This in
       practice	means that the values displayed	with pfsview maybe higher than
       expected. To compensate for this	incompatibility	we suggest to use pfs-
       absolute	command:

       pfsinrgbe measured_luminance.hdr	| pfsabsolute 1	179 | pfsview

       This is not necessary when RGBE files are saved using pfsoutrgbe, Radi-
       ance  package,  mkhdr  or  Photospheare.	This is	also not relevant when
       only relative absolute values are considered.
