This is small collection of tools to allow conversion between OpenEXR
and SketchBlock formats.
Currently it consists of just the EXRtoSketch command.
OpenEXR is a format for HDR images and is an output option in blender,
thus one use of these tools will be to exchange data between blender and
SketchBlock with no information loss.
Blender can also output multiple passes in OpenEXR format allowing for t
he use ofSketchBlock for post processing on the image at full dynamic range.

NAME
EXRtoSketch - A tool to convert OpenEXR image files into SketchBlock
projects.
FORMAT
EXRtoSketch <EXRFILE> <SKETCHPROJECT> [ INVERT ]
TEMPLATE
EXRFILE,SKETCHPROJECT/A,INVERT/S
FUNCTION
OpenEXR is the industry standard HDR (High Dynamic Range) format
developed by Industrial Lightt and Magic. As SketchBlock works in HDR
internally it's useful to be able to directly import such data without
losing dynamic range as you would when importing via the DataTypes
system.
OpenEXR files can contain layers with different types of channels,
EXRtoSketch will extract any layers containing ARGB data and create
the equivalent layers in the destination sketchblock project.
OpenEXR files may be exported from blender, in both EXR mode (rendered
image) and also MultiLayer mode. (seperatte passes)
Due to bug in blender 2.43 through to at least 2.53, imagery
in the MultiLayer variation is inverted, thus EXRtoSketch comes with
an option to invert the image when decodeing.
