Description: CColor - RGB and HLS combined in one class
The CColor class emerged from the need to manipulate color in the HLS model, meaning I needed the ability to directly change attributes like luminance or saturation. The HLS model makes it very easy to draw such things as color gradients between any color. Perhaps Windows 2000 will support the HLS (or the similary HSB) color model, but I do not want to wait until the release. On the other hand my code should also work under NT 4.0 and Win95/98. The CColor class encapsulates the long known type COLORREF and extends it with the HLS color model. A CColor object represents a color, whose RGB and HLS properties can be directly read and manipulated. It makes the use of type COLORREF and the associated macros superfluous.

Description: The purpose of a comb filter is to separate a composite video signal's luminance (Y) information from its color (C) information. There are several ways to perform Y/C separation and comb filters are the most common. There are different types of comb filters and they vary widely in performance. The differences are directly observable in the video artifacts that exist after separation. In this article I will explain what artifacts to expect form each type of Y/C separation filter and where to look for them. The best way to understand the advantages of the different comb filter technologies is to start with a little information about the composite video signal.
