Hi Mark,
In Essential PDF we do have support for drawing multi line text within a specified rectangle. We can get the string that fits inside this rectangle and use it to draw on another rectangle. The DrawMultiText() method of IPDFGraphics return string that do don’t fit inside the specified rectangle this can be used to get the clipped text. Here is a sample attached for you to refer with.

Please let me know if you have any other questions.
Thanks,
Ajish.
