    Posted: 23 Nov 16 at 8:33PM
Hello,

I'm trying to use new PDFium renderer with C++ DLL version of Quick PDF library.
SetPDFiumFileName always returns 0. To ensure the path is specified correctly, I called SetCairoFileName with the name of the same PDFium DLL, and the function succeeded.
What is the correct way modifying the renderer?

Thanks,
Natalia.

Hi Natalia,

this is from the reference guide:
If PDFium is used, the SetPDFiumFileName function should be used to set the path to the DPLPDFium DLL, either 32-bit or 64-bit as appropriate.
Second should be SelectRenderer:
http://www.debenu.com/docs/pdf_library_reference/SelectRenderer.php
If this doesn't succeed then there's a prob with your pdfium-installation i think.

If you'll succeed it would be kind posting a "first steps using PDFium-renderer" into the samples section ;-)


Cheers and welcome here,
Ingo

Ingo

Thanks Ingo,
Do I have to install PDFium, or it is enough to copy QPL1311PDFium64.dll, and set PDFium file name in the application?
In my environment setting file name always fails, setting renderer seems to succeed even without setting file name, but, as far as I understood, default renderer is used anyway.

on a 64-bit-system the 64-bit-dll should be in the system32-path.
on a 64-bit-system the 32-bit-dll should be in the syswow64-path.
on a 32-bit-system the 32-bit-dll should be in the system32-path.
Please be sure to use the QuickPDF-64-bit-dll as well.
Cheers,
Ingo

I don't think my problem is in the path. I tried specifying the full path, place the DLL in the working folder or System32, it did not make any difference. When I call SetCairoFileName with the same DLL on the same location, the function succeeds.
My test app is simple 64 bit app running on 64  bit Windows 2012 R2, all DLLs are 64 bit.

Perhaps it makes sense to post the relevant code part?
Another idea:
If the cairo call works then cairo files and installation is okay.
If the pdfium call doesn't work then ... ;-)
Cheers,
Ingo

I asked Debenu support the same question. They answered that the PDFium DLL is the release version is corrupted.

Did the support folks tell you how to get a valid PDFium DLL?  We downloaded v13 last week, and I am having the same problem when I call SetPDFiumFileName().

So stay tuned.
