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


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

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

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

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


       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:


              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.


        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).


       pfsout(1) pfsinppm(1)


       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
