I'm developing an application that uses Spire.PDF (free version atm, we'll upgrade when we see it fits our needs) to find the location of certain elements in a PDF diagram exported by another application.
The problem is that when we call FindAllText() on a page the function only retrieves text until an arbitrary X coordinate in the diagram (about 9/10 of the width of the pdf is found).
I'm attaching an image showing the portion of the pdf that is found and the one I'm not getting any results even though there is text.

I would like to know if this is just a limitation of the free version or what.
Thanks in advance,
Carles
