Detailed Description

This class provides an easy to use painter object which allows you to draw on a PDF page object.

During all drawing operations, you are still able to access the stream of the object you are drawing on directly.

All functions that take coordinates expect these to be in PDF User Units. Keep in mind that PDF has its coordinate system origin at the bottom left corner.
