Hi there
I am trying out Pdfium.Net before I buy a license.
I am using the WPF control.
Viewing very small PDF files (under 500 KB) is fine.
However I tried an 800 KB PDF file containing 27 pages, and a 15 MB PDF file containing 90 pages.
The following exception is thrown:
System.StackOverflowException was unhandled
Message: An unhandled exception of type 'System.StackOverflowException' occurred in Patagames.Pdf.Wpf.dll
Note that all the PDF files I have been testing only contain text, no images.
I am using the 32 bit control, as other libraries in my app are 32 bit as well.
Therefore I cannot try the 64 bit control as this breaks my app.
The code I am using is inside the constructor of the XAML:
InitializeComponent();
//Gets the location of the current assembly as URI
string codeBase = System.Reflection.Assembly.GetExecutingAssembly().CodeBase;
UriBuilder uri = new UriBuilder(codeBase);
string assemblyPath = Uri.UnescapeDataString(uri.Path);
//Gets directory for assembly
var base_path = System.IO.Path.GetDirectoryName(assemblyPath);
//Combine path to Pdfium.dll
var path = System.IO.Path.Combine(base_path, @"x86\pdfium.dll");
//Initialize library
PdfCommon.Initialize(null, path);
pdfViewer.LoadDocument(@"c:\test.pdf");
I tried adding the following code before calling pdfViewer.LoadDocument:
PdfCommon.IsCheckForMemoryLeaks = true;
pdfViewer.OptimizedLoadThreshold = 1;
pdfViewer.PageAutoDispose = true;
pdfViewer.TilesCount = 1;
pdfViewer.UseProgressiveRender = true;
pdfViewer.UseLayoutRounding = true;
pdfViewer.ViewMode = Patagames.Pdf.Net.Controls.Wpf.ViewModes.SinglePage;
The PDF Viewer now shows the first page of the document.
If I try to go to the next page, the same exception is thrown.
Pdfium.dll version 3.17.2.2704
Patagames.Pdf, version 3.16.2.45
Patagames.Pdf.WinForms, version 3.14.3.45
Patagames.Pdf.Wpf, version 3.14.3.45
Please assist.
Thank you.
