I'm trying to measure the y position of a single line text field, specifically at the baseline position, i.e where the bottom of the letters without tails like 'y' has sit. I guess I either need to know the y position at baseline or the height of the font not including the stuff under the baseline.

The reason I'm needing to do this is that I'm using alive pdf and i'm trying to add text in the same relative position on the pdf as the window that the user designs something, and alive pdf's addText function sets y a the baseline position it seems.

Thanks in advance!
