Hello Jwalit,

For understanding the problem we need to reproduce the problem on our side. Could you send us your BIG TIFF file for tests? If yes, please upload your file to any free upload service, for example Google Drive, and send us (to support@vintasoft.com) an URL for downloading the file.

Best regards, Alexander

Hello Jwalit,

Thank you for PDF and TIFF file. We tested provided files in VintaSoft ASP.NET Core Document Viewer Demo and was not able to reproduce the problem with "UI freeze".

Here are steps, which we did:

Open VintaSoft ASP.NET Core Document Viewer Demo project ("[SdkInstallPath]\VintaSoft\Imaging .NET v12.2\Examples\ASP.NET Core\CSharp\AspNetCoreDocumentViewerDemo\AspNetCoreDocumentViewerDemo.Net7.csproj") in Visual Studio.
Run the project in Chrome.
Copy files "1 GB.tif" and "416 MB.pdf" to the "[SdkInstallPath]\VintaSoft\Imaging .NET v12.2\Examples\ASP.NET Core\CSharp\AspNetCoreDocumentViewerDemo\wwwroot\UploadedImageFiles\{SessionId}\" folder.
In "File" menu click the "Previously uploaded files" button and open file "1 GB.tif" => File was opened and rendered without problems.
In "File" menu click the "Previously uploaded files" button and open file "416 MB.pdf" => File was opened and rendered without problems.

How to reproduce your problem? Please send me a step-by-step guide.

Best regards, Alexander
