Wrong coordinates given by Jcrop

[andreipetrescu95]

I am using Jcrop to get the coordinates of PDF file that is loaded in an iFrame. The problem is that Jcrop does not take into account when i scroll down in the document, so I get the wrong results. It seems to me that it gets coordinates based on the beginning of the iFrame, and not the document.

Am I doing something wrong or is the plugin not able to do that?
