LineDDA
Enumerate every point on a line
Here is a nice little class we can use to enumerate each and every point on a line. We are using the Digital Differential Analyzer (DDA) approach.
The idea of drawing a simple line is well supported by just about every graphical framework. What is less sure is the ability to enumerate through a set of points so as to choose just which points we are interested in.
LineDDA also graphically demonstrates support for Positive Slope, Negative Slope, Zero and No Slope.
