NAME

       pfsinexr - Load images or frames in OpenEXR format

SYNOPSIS

       pfsinexr [--keep-rgb] (<file> [--frames <range>] [--skip-missing])  [<file>...]

DESCRIPTION

       Use this command to read frames in OpenEXR format. The frames are converted to pfs stream and send to the
       standard  output.  This  command  can  read arbitrary channels from OpenEXR files; color channels XYZ are
       however specially handled (see option keep-rgb).

       pfsinexr reads also all string attributes from OpenEXR file  and  write  them  as  tags  in  pfs  stream.
       Attributes  of  other types are ignored. If attribute name contains a colon (:), the part before colon is
       treated as a channel name and the attribute is assigned to that channel (similar notation as command line
       argument of pfstag program).

       pfsinexr recognizes OpenEXR standard attribute WhiteLuminance and multiplies the data by  that  value  to
       get  absolute  luminance  values  (see  also  --fix-halfmax  switch  in  pfsoutexr). Additionally the tag
       LUMINANCE is set to ABSOLUTE unless OpenEXR files contains attribute LUMINANCE  set  to  semething  else.
       That is the channel Y is assumed to represent absolute luminance levels in cd/m^2.

       If  an  OpenEXR  file  contains  'Z' channel, it is renamed to 'DEPTH' to avoid conflict with the Z color
       channel for the XYZ color space.

       Details on the format of the pattern file names, which are used for reading multiple frames, can be found
       in the manual page of pfsinppm.

       To automatically recognize a file format from the extension, use pfsin command instead.

       --keep-rgb
              By default, color channels R, G and B from an OpenEXR file are converted to XYZ color space, which
              is suggested format for color data in pfs. When keep-rgb option is specified, color  channels  RGB
              are stored as they are without any conversion.

EXAMPLES

        pfsin memorial.exr | pfsout memorial.hdr

              Converts from one HDR format to another

BUGS

       pfsinexr and pfsoutexr can not take stdin / stdout as an input/output (dash '-' instead of file name).
