Hello,

How I can read pdf file from InputStream directly?
I tried to use my own wrapper that implements PDFStream but nothing.
By the way, InputStream from getAssets() working good. If I'm trying to use another streams -- still getting an error "Open Failed: Damaged or Invalid PDF file"

Please help me

Hi,
please check PDFSimple class from RDPDFReader module, go to Open method, here you will find an example of open file from InputStream.
Check PDFFileStream class.

You can also try with
m_doc.OpenMem(byte[] data, String password)
For more info check this : www.radaeepdf.com/documentation/javadocs...:A-java.lang.String-

Hi,

I've checked code with PDFStream and PDFFileStream classes. I want to open file from InputStream directly (using ZipInputStream) but not from file/buffer. Also I think that we can use only "seekable' streams (with reset(), skip() and markSupported() flag).

Hi,
sorry but with our sdk you can open stream only using one of the methods I suggested you before.

Hi,

What you need to do, is to create you own class that implements PDFStream in that class you can use your input stream..and pass your class to m_doc.OpenStream

What problems did you face while implementing this behavior?

Hi,

Yes, As I wrote before, I've created my own class that implements PDFStream (similar to PDFAssetStream). And unfortunately my source stream can't support skip() and reset() methods -- they raises IOException. By the way, main task is opening PDF from InputStream from ZIP archive directly.

Tnahks.
