Hello so i was using this package to show pdf in my app pub.dev/packages/flutter_full_pdf_viewer and pdf package pub.dev/packages/pdf to create the pdf.

This is the code i use to create the pdf and navigate to pdf viewer page :

Consider the following PostScript file

I'm trying to interface PDFium with Cython and ran into these defines/signatures:

I have an Android app which uses the standard PdfRenderer to render PDFs. It is working so far so good and I managed to get rid of the most of the errors in the app.

The only error I have no idea how to get rid of is:

I am working with android pdfviewer lib to open and read a pdf, found at : https://github.com/barteksc/AndroidPdfViewer

But i got an error when i try to launch the pdf :

E/zygote64: No implementation found for long com.shockwave.pdfium.PdfiumCore.nativeOpenDocument(int, java.lang.String) (tried Java_com_shockwave_pdfium_PdfiumCore_nativeOpenDocument and Java_com_shockwave_pdfium_PdfiumCore_nativeOpenDocument__ILjava_lang_String_2)

E/PDFView: load pdf error java.lang.UnsatisfiedLinkError: No implementation found for long com.shockwave.pdfium.PdfiumCore.nativeOpenDocument(int, java.lang.String) (tried Java_com_shockwave_pdfium_PdfiumCore_nativeOpenDocument and Java_com_shockwave_pdfium_PdfiumCore_nativeOpenDocument__ILjava_lang_String_2)

i tried with differents implementation of the dependency but none worked :

I want to extract the text content of this PDF: https://www.welivesecurity.com/wp-content/uploads/2019/07/ESET_Okrum_and_Ketrican.pdf

Here is my code:

I am trying to compile PDFium taken from the chromium source code with MSVC 141. The code is a custom allocator. You can see that the custom allocator can be instantiated with wchar_t no problem. wchar_t is apparently arithmetic. However, passing it into a vector fails the static assertions. The following code gives a static assertion, which I do not expect:

The Built-in Chrome PDF Viewer does not fully load large PDF files for authenticated users.

Steps to reproduce in my environment:

1. In Visual Studio 2019 create a new WebForms project with Individual User Accounts authentication
2. In solution explorer create some folder e.g. MyPDFs and put inside some large pdf file.

3. Secure this folder with web.config:

   and for this testing purposes set runAllManagedModulesForAllRequests to true:

4. Run this site with IISExpress and navigate to ~/MyPDFs/A17_FlightPlan.pdf in my case it is https://localhost:44302/pdfs/A17_FlightPlan.pdf

5. The login screen appears, after user successful logins the pdf is partially rendered (only first page) by built-in Chrome PDF viewer (pdfium)

6. When you remove authorization rule from web.config, or you put the PDF file to some other location, it is loaded correctly

7. The same behavior I can reproduce on production - Full IIS

8. Other browsers work fine: FireFox, EDGE, or even Chrome with replaced built-in PDF viewer for Adobe Acrobat reader extension

Where could be the problem? Are the headers OK?

I'm building a UWP Viewer for the Pdfium library(pdfium.dll). pdfium.dll is a c++ class library. In my Visual Studio Solution, I have two UWP projects. First Project(PdfiumViewer) is a UWP Class Library which imports functions from pdfium.dll and creates user controls. Eg:
