SYNOPSIS

DESCRIPTION

14       Use this command to read frames in OpenEXR format. The frames are  con‐
15       verted  to pfs stream and send to the standard output. This command can
16       read arbitrary channels from OpenEXR files; color channels XYZ are how‐
17       ever specially handled (see option keep-rgb).
18
19       pfsinexr  reads  also all string attributes from OpenEXR file and write
20       them as tags in pfs stream. Attributes of other types are  ignored.  If
21       attribute  name  contains a colon (:), the part before colon is treated
22       as a channel name and the attribute is assigned to that channel  (simi‐
23       lar notation as command line argument of pfstag program).
24
25       pfsinexr  recognizes OpenEXR standard attribute WhiteLuminance and mul‐
26       tiplies the data by that value to get absolute  luminance  values  (see
27       also --fix-halfmax switch in pfsoutexr). Additionally the tag LUMINANCE
28       is set to ABSOLUTE unless OpenEXR files  contains  attribute  LUMINANCE
29       set  to  semething  else. That is the channel Y is assumed to represent
30       absolute luminance levels in cd/m^2.
31
32       If an OpenEXR file contains 'Z' channel, it is renamed  to  'DEPTH'  to
33       avoid conflict with the Z color channel for the XYZ color space.
34
35       Details  on  the  format  of the pattern file names, which are used for
36       reading multiple frames, can be found in the manual page of pfsinppm.
37
38       To automatically recognize a file format from the extension, use  pfsin
39       command instead.

41
42       --keep-rgb
43              By  default,  color channels R, G and B from an OpenEXR file are
44              converted to XYZ color space,  which  is  suggested  format  for
45              color  data  in  pfs.  When  keep-rgb option is specified, color
46              channels RGB are stored as they are without any conversion.

BUGS

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