Graphics Programming with GDI+

7.7. Skewing Images

So far, we have seen that we can draw various images on graphics surfaces by using DrawImage. We have also seen how to implement rotate, flip, fit-height, fit-width, and zoom features. An imaging application may need to provide even more features, including scaling, skewing, and high-performance rendering. Using GDI+, we can do all of this very easily. We will discuss some of these issues in this chapter and some of them in Chapter 8.

The DrawImage method has about two dozen overloaded forms—one of which lets us provide the destination points for an image. The original image will be drawn after its coordinates are mapped to the destination points—a process called skewing. We will see an example in a moment. First let’s examine ...
