A client, asked me a feature of free drawing directly on a pdf
Is there any sort of way i can achieve this with your libraries?

Hi Ric,

At present we do not have support for free drawing on PDF document using Syncfusion PDF Viewer.

As a workaround, please refer to the KB in the link below, in which we can perform free drawing on a PDF document using Syncfusion libraries.

Hi Ric,

We are unable to reproduce the mentioned problem in our latest Essential Studio Volume 3, 2015.
The sample provided in the previous update will work as expected only after Essential Studio Volume 2, 2015 version or later versions.
Can you please upgrade to our latest version from the below link to get this issue resolved?
