pfsoutimgmagick(1)	    General Commands Manual	    pfsoutimgmagick(1)

NAME
       pfsoutimgmagick - Write images or frames	using Image Magick library

SYNOPSIS
       pfsoutimgmagick	[--linear]  [--quality	<val>] [--bit-depth] [--frames
       <range>]) <file>	[<file>...]

DESCRIPTION
       This command can	write images or	frames in the multitude	of image  for-
       mats  supported	by  the	 ImageMagick library. This includes but	is not
       limited to: BMP,	JPG, PNG, GIF, EPS, TIFF, DPX. See the manual page  of
       ImageMagick for the full	list of	available formats.

       pfsoutimgmagick	reads images or	frames in pfs format from the Standard
       Input and writes	them under the specified file name(s).

       The input of pfsinimgmagick must	be within 0-1 range. If	LUMINANCE  tag
       set  is	set  to	 RELATIVE or ABSOLUTE, the linear values will be gamma
       corrected, assuming sRGB	color space. Use --linear  switch  to  disable
       gamma correction.

       The images are stored using the bit-depth for which the ImageMagick li-
       brary was compiled (default is 16 bit). Note that some formats (for ex-
       ample JPEG) do not support encoding more	than 8 bits per	color channel.
       To use higher bit-depths, store images in the PNG format.

       This command stores 'ALPHA' channel if it is present in the pfs stream.

       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.

       --quality <val>,	-q <val>
	      Set JPEG/PNG compression level from 1 to 100. Default 75.

       --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 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
       pfsoutimgmagick can not write frames to the standard output.
