(About the author)
 
     A very basic set of modules with mostly integer only coded methods for each of Line, Circle, Ellipse to compare Non Aliased vs AntiAliased performance. We show VB is very fast, GDI+ debatably so, but very good quality and homespun routines are a viable alternative to avoiding GDIPlus dependency We demonstrate Wu and Gupta-Sproull algorithms for AntiAliased Lines, Bresenham style algorithms for Circle and Ellipse. AntiAliased Circle and Ellipses are by an algorithm of my invention based on Bresenham methods with Wu style dither techniques (and a fair bit of stuffing around was required to get them right) RVT 20 Oct 2008

And the first (and only) thing we see is the message "MISSING: GDI+ Type Library 1.05"

Juca,

The required Typelib is here at PSC
search for "GDI Type Library" and follow the instructions. Alternatively it is also elsewhere on the net.

Ron, thanks for this great piece of code. I've been looking for a native-VB implementation of Xiaolin Wu's antialiasing algorithm for some time, and yours is far and away the best I've found. Great work (as always).
