Using even the most simple example, if I create an empty page, and then try to add a polyline annotation to it, the method returns false. For example, if I do the following, AddAnnotPolyline returns false:
AddAnnotInk does not exhibit this problem. I am using the latest beta version, which is 3.5 beta 8. Is this a known issue? As a side note, is it possible to add a quadTo function to the Path class? It's really inconvenient to have to use a cubic bezier for the calculations I'm doing.
I was using a much more complex example in my code, and I think my PDF coordinates were incorrect. Regardless of what happened, I no longer seem to have the error with adding the polyline annotation, so I apologize for the confusion.
