An exception occurs when using Aspose.PDF for .NET from GAC under .NET 4.0

Hi Team,

We recently updated the Aspose.PDF.dll version 23.6.
After updating we are getting below error while adding a Image to the PDF.

I could find the same error reported in below thread long back but couldn’t find any solutions. Is there a fix/any workaround for this?

https://forum.aspose.com/t/could-not-load-file-or-assenbly-aspose-imaging-version-22-5-0-0/247892

Code snippet:
Pdf.Document pdfDoc = new Pdf.Document();
using (MemoryStream byteStream = new MemoryStream(documentData))
{
pdfDoc.Pages.Add();
Pdf.Page page = pdfDoc.Pages[1];
page.AddImage(byteStream, page.GetPageRect(false));
}
return pdfDoc;

Error Message:
Invalid image stream (Could not load file or assembly ‘Aspose.Imaging, Version=23.5.0.0, Culture=neutral, PublicKeyToken=716fcc553a201e56’ or one of its dependencies. The system cannot find the file specified.)

Would you please try using 23.10 version of the API and if issue still persists, please share your sample document with us. We will test the scenario in our environment and address it accordingly.

Hi @asad.ali,

I am facing the same issue when using 23.10 as well. It is working fine in Aspose.PDF.dll 12.0 version.

Also I am unable to upload the sample application (Zip File) here. Is there any other way to share the files.

Thank You!

Hi @asad.ali,

I am still facing issue uploading the sample application.

Could you please just host a simple web application with below code to convert any image to PDF?

byte[] bytes1 = System.IO.File.ReadAllBytes(“”);
Pdf.Document pdfDoc = new Pdf.Document();
using (MemoryStream byteStream = new MemoryStream(bytes1))
{
pdfDoc.Pages.Add();
Pdf.Page page = pdfDoc.Pages[1];
page.AddImage(byteStream, page.GetPageRect(false));
}
pdfDoc.Save(“”);

It is replicating only in a web application hosted in IIS. Its working fine in a console application.

Thank You!

Would it be possible for you to share your sample application in .zip format? You can simply remove the DLLs from the *bin folder(s) and reduce the package size to allow uploading here with your post. We will perform initial investigation in our environment and address the issue accordingly.

Hi @asad.ali,

We have a restriction at organizational level for uploading files.
Could you please try creating a simple web application with below code and replicate it?

byte[] bytes1 = System.IO.File.ReadAllBytes(“PATH_TO_ANY_IMAGE_FILE”);
Pdf.Document pdfDoc = new Pdf.Document();
using (MemoryStream byteStream = new MemoryStream(bytes1))
{
pdfDoc.Pages.Add();
Pdf.Page page = pdfDoc.Pages[1];
page.AddImage(byteStream, page.GetPageRect(false));
}
pdfDoc.Save(“PATH_TO_SAVE_PDF”);

Note: It is replicating only in a web application hosted in IIS. Its working fine in a console application.

Thank You!

@hariprasanth1998

Can you please share the specifications of web application? Could it be any e.g. MVC, ASP.NET Web Forms? Are you using .NET Core?

Hi @asad.ali,

I replicated using ASP.NET Web Forms. Not using .Net Core.

Thank You!

@hariprasanth1998

We tested using 23.11 version of the API in ASP.NET WebForms application and were unable to notice any issues.

Hi @asad.ali
