Organization

Basically, I've been using this area as a scratch pad of sorts. As I complete things, and clean-up I'll probably just add a link here for reference.

Scratch Pad

The non-linear relationship between color values and actual light intensity is usually approximated by (or calibrated to match) a power-law function (aka gamma function, hence the technical term gamma), i.e.:

gamma formula

where x symbol is the internal representation normalized to the range [0...1], output light intensity is the actual output light intensity, and gamma symbol is a value typically somewhere between 2.0 to 2.4, though in the professional image processing world a value of 1.8 is also common.

Keyword Addition Example

This outlines the steps to add a new keyword to the documentation. In this case deprecated

Completed

  • The source and notes on the LaTeX markup used in the documentation.
  • The change-log has been reviewed and the results are here.
