pfsoutppm(1)		    General Commands Manual		  pfsoutppm(1)

NAME
       pfsoutppm,  pfsouttiff,	pfsoutrgbe, pfsoutexr -	Write images or	frames
       in one of the several formats

SYNOPSIS
       pfsoutppm (<file> [--srgb] [--frames <range>])  [<file>...]

       pfsouttiff (<file> [--srgb] [--frames <range>])	[<file>...]

       pfsoutrgbe (<file> [--frames <range>])  [<file>...]

       pfsoutexr (<file> [--frames <range>])  [<file>...]

DESCRIPTION
       This command can	be used	to write pfs frames piped to standard input in
       one  of the several recognized formats. See the manual page of pfsinppm
       to get a	list of	available formats.

       To write	images to standard output use a	single	dash  '-'  instead  of
       filename.

       Each  file  name	 can  contain  a %d pattern, which is substituted with
       frame numbers. The pattern has the same syntax as C printf command. For
       example,	you can	use %04d to make the frame number four digit with pro-
       ceedings	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.

       --srgb, -s
	      Apply the	sRGB non-linearity (approximately  2.2	gamma)	before
	      writing  a  file.	 This can be used instead of using pfsgamma -g
	      2.2 to store the result of some tone-mapping operators. The  op-
	      tion  will  compress  contrast to	make sure that tone values are
	      properly shown on	a display. It should be	only  used  with  lin-
	      earized  (not gamma corrected) images that are normalized	to the
	      0-1 range.

       --bit-depth <val>, -b <val>
	      Enforce bit-depth	(per color channel). The  allowed  values  are
	      from  8  to  32.	If  not	 specified, the	bit depth from the pfs
	      stream ('BITDEPTH' tag) will be used instead. If the  'BITDEPTH'
	      tag is missing, the ImageMagick default value will be used (usu-
	      ally 16).	The bit	depth of actually stored file may be lower  of
	      that  specified,	if the file format does	not support higher bit
	      depths.

EXAMPLES
	pfsin memorial.tiff | pfsoutrgbe memorial.hdr
	      Converts from one	HDR format to another

       pfsin test.jpg |	pfsout test.png
	      Convert from one image format to another.

	pfsin --linear test.jpg	| pfsout --srgb	test.png
	      The same as above, but  apply  inverse  gamma  correction	 after
	      reading  an image	(--linear) and then apply gamma	correction be-
	      fore writing an image (--srgb).

BUGS
       Writing TIFF files with pfsouttiff seems	to be broken,  but  pfsoutimg-
       magick  can be used instead. pfsout will	attempt	to use pfsoutimgmagick
       and fall	back to	pfsouttiff if pfstools were not	compiled  with	Image-
       Magick.

       Please  report  bugs  and  comments on implementation to	the discussion
       group http://groups.google.com/group/pfstools
