Subject How to add markups to an existing OCG in a pdf
Date Mon, 10 Apr 2017 13:34:00 GMT


I want to implement functionality to allow user to create layers(Optional
content group). Then, allow them to select a layer and add markups, text to
that layer. I have implemented the functionality to create layers using the
LayerUtility class. But, I am not able to modify an existing layer.

I tried to convert the PDOptionalContentGroup to PDPage by first converting
PDOptionalContentGroup to COSDictionary and then creating the PDPage from
the COSDictionary. Then making the changes in the PDPage. But this creates
an invalid PDPage.

So, how do I modify an existing layer(optional content group) in a pdf?



Best regards,
