Hey,

I am opening PDF using stream OpenMem and for some reason making annotations is disabled (annotations button has grey background)
I am using demo license.

So how to make file read-only and writable? Maybe I am accidentally setting read-only option somewhere.

I am looking at demo project and can't really see why pdfs opened from navigation screen are writable, but pager, asset, sd card are not.

Update: Seems if im loading directly PDF from disk, then it seems all is good with annotations. My question is this then: are you able to edit if you open it from memory stream after purchasing license?

Hi,
OpenMem and OpenAsset are read only.
I suggest you to look at PDFMemStream class that handles writable stream (demo project doesn't implement this class).

I suggest you to look at PDFViewAct to better understand how the library works, here you will find some open methods usage.
- pager has a different implementation (PDFPagerAct)
- sdcard is writable, in the demo project the "Open From sdcard" button is searching for that pdf : "/sdcard/test.pdf" (you can edit it in MainActivity class)

The demo project has all the features available with the purchased one, so you can test and check all you want.
