At the moemnts I'm just setting the width in the bounds to be 100 and it obviously doesnt always show all of the text! Thanks!    Report

I'm afraid I don't completely understand your goal.  Are you trying to create a text object that is exactly the size of the string?  Please explain in more detail.

Is there a way to measure the width of the text within an annotation?  Depending on the font size it may wrap the text to a new line and I need to be aware of that wrapping as I would want to then increase the annotation height or decrease the font size so that all of the text is visible within the annotation. Visually I can see that it doesn't fit, but is it possible to detect in code that some of the text is being cut off? In my instance I'm using version 15 of the .Net assemblies.    Report

Thanks for your quick response, it's much appreciated.    Report

I've requested that if this isn't a bug, that the engineers provide a way to calculate the small permanent margin. Greg Ross LEADTOOLS Technical Support    Report
