Excerpt of article text...
In a previous issue (2.3) we saw how to speed up graphic operations like rotation. It did require a bit of coding, but proved to be quite fast. A faithful reader of this column actually used the code and tips for a real-life application, and we have worked together in order to make it even faster and more readable. Some of the things we did together will serve as a basis for this article.
We will produce a basic graphics library that'll extend the Picture object, making the library more portable and the code using it more readable. We will also make full use, when possible, of the .Transform method of the RGBSurface object. This method, which provides a very fast way of mapping colors and applying transformations based on the mappings, proves to be very convenient in some cases.
