We have a PDF suppplied by a customer which has been created in Acrobat 9 possibly
from excel. The problem is that the y coordinates for the text is -5mm as shown in pitstop, yet the text i more like +5mm, this is causing a problem with our online system where it cuts off the edge of the text, I have checked for any hidden items of which there are none, I can't seem to figure this one out.
I hope someone has some answers.
thanks in advance

But why do we get minus coordinates when there is nothing else on the page?

The coordinates are determined by the CropBox and the Media box of the page. Coordinates don't automatically start at 0,0. In JavaScript the coordinates are transformed to create two convenient coordinate spaces using the Crop box and the media box as the references. I don't know what pitstop is doing, but I suspect, since it's a print oriented tool, that it's using the Media box as a reference. But in the scheme of things it doesn't matter too much. All coordinates are relative.
