Hello friends.
Today I came across a problem I don't know how to solve, I was hoping someone could give me some light.
This attached document is a regular pdf , edited externally with some annotations and highlights in other pdf application (with Foxit)
When we try to open it with OpenStream it returns a -3, given the documentation of your method (posted below) it seems it is damaged or it has invalid format so it won't open. We have been able to open it in other viewers, like Polaris and the PDFViewer in Android.
I was wondering if there is something I could do, or it may have something to do or any workaround to end up showing the pdf.
Any idea or sugestion will be muh apreciated.

Thanks in advance. Have a good day.

Hi,
can you reproduce this issue with the demo project? What version of the library are you using?
I have tested your pdf with the last version of the library and it works properly.

Hi,
if you are opening stream using http look at this important knowledge base .
