PROGRAM:

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.
