it's not very clear from your posting whether you want to create a 
flowable and use the doctemplate methods or just create a canvas and 
draw on that directly.

The doctemplate classes use a list of flowables ie things which are 
flowed onto the space allocated in a frame; when the draw method of a 
flowable is called the framework has normally adjusted the drawing space 
so that the origin is at the lower left corner of the space requested in 
a call to the flowable's wrap method. That way the flowable doesn't have 
to do its own coordinate transformations. It always assumes it's at the 
origin. The framework lays out flowables starting at the top of the 
frame and continuing until all vertical space is used up. The story then 
automatically proceeds to the next frame (or page).

Creating a canvas and then using canvas method to draw on it is often 
more suitable for simple projects which have a fixed layout.
