EXRTools

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.
