Where can i find the documentation of GemBox.Pdf 13?

Hi, I have an old version of GemBox Pdf, number 13.
I need to change the font color of a document.
Where can I find the version 13 documentation?

Hi Gabrio,

Unfortunately, GemBox.Pdf 1.3 didn’t have support for writing text.
This was added in GemBox.Pdf 1.5.

Here is a Version History page:

Also, here are help pages for GemBox.Pdf 1.3:
