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
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.
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.
