Exrviewer

Short: ExrViewer

Version: 0.1

This is a simple viewer for high dynamic range image files in the OpenEXR format
developed by Industrial Light and Magic. 

It is based on the exrdisplay reference implementation, with a reaction GUI
replacing the FL based one of the original. This is an 'as is' release prompted
by my current hardware problems! 

Installation:

Copy the contents of the CTL directory to the location of your choice and create
an assign "CTL:" pointing to that location.

Copy the executable to the location of your choice.

Usage:

There are two executable one has support for the CTL (colour transform language)
one is built without, both require large amounts of stack (set to 1M or more to
be safe), there is no stack cookie built in at present so you must set the stack
before usage. 

To view a file 

stack 1000000
exrviewer myimage.exr

A window will open with the "display" window portion of the image centred. You
can adjust the exposure and knee values to vary the display of the high def
image. 
You may save a snapshot of the current display by clicking on the button at the
bottom right hand of the window. It will save the image as a ppm file in ram:

For more options do

exrviewer --help

There are some example high definition images on the OpenEXR website
