NAME

       pfsout - Read pfs frames from stdin and write them in the format determined by the extension of the file name

SYNOPSIS

       pfsout pfsout <file> [<file>...]

DESCRIPTION

       This  command can be used to write pfs frames piped to standard input in one of the several recognized formats. The proper format is deter-
       mined by the extension of the give file name. To get a list of recognized formats and extensions, execute:

	 pfsin --help

       This command is a front-end for pfsout* programs for writing images: pfsoutrgbe, pfsoutexr, etc. Based on the file  extension,  appropriate
       program	is  executed.  If  two different file format are given as parameters, two different program for writing images are executed. Addi-
       tional options starting with dash '-' can be passed to pfsout* programs. The following rules apply for passing  the  options:  the  options
       given before any image file name (or %d pattern) are passed to all pfsout* programs. Options given after image file name are only passed to
       the program executed for that file(s). Note also that all  option  that	take  an  argument  (except  --frames)	must  given  in  the  form
       --option=value, that is without a space between an option and its argument.

EXAMPLES

	pfsin memorial.tiff | pfsout memorial.hdr

	      Converts from one HDR format to another

BUGS

       This command currently does not handle multiple frames given with a %d pattern in case of LDR formats: JPEG, PNG, PNM.

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 pfs-
       inppm 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 proceedings 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 option will compress contrast to make sure that tone values are properly  shown
	      on a display. It should be only used with linearized (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  (usually  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 before writ-
	      ing an image (--srgb).
