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
       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 writing an image (--srgb).

BUGS

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

       Please    report    bugs    and    comments    on    implementation    to    the     discussion     group
