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 assumued 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).
