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.:
where is the internal representation normalized to the range [0...1], is the actual output light intensity, and 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.
Some text here just f(x) = x̂Γ for comparison.
Keyword Addition Example
This outlines the steps to add a new keyword to the documentation. In this case deprecated
- first determine where the descriptive passage goes then add it
- update the syntax diagram in the appropriate places
- update the syntax diagram in the Quick Reference
- update the Identifiers and Keywords list
- document any other place(s) that it's used
- add a table of contents entry
