You do not have to waste your time, reading this example, all you really need is to carefully study all the three images shown in this section (12.3.2.1), and try to figure out what the differences mean, and possibly, what caused them. Here are some hints: the majority of problems are related to the size of the drawing surface, as well as scale, which are only completely revealed if the drawing is not done right next to the edges of the drawing surface.
- We will revisit this program again in the above mentioned section 12.3.4, where we will see a better and more efficient way to handle displacements in cairo code.
+ We will revisit this program again in the above mentioned section 12.3.4, where we will see a better and more efficient way to handle displacements in cairo code. By then you should also have a much better understanding of 'canvas' (drawing surface) size and scale related issues, which are there finally addressed in full extent.
