Cannot allocate so many bytes. Use LoadPartialPixels instead

Aspose.PDF Product Family

Hi,
I am trying to convert image into pdf but it is throwing an exception - “Cannot allocate so many bytes. Use LoadPartialPixels instead.”

  int height = 200;
  int width = 200;
  string filePath = @"C:\2023-07-12117A-ED_F1_specs_postprocessed.jpg";
  string pdfFile = @"C:\2023-07-12117A-ED_F1_specs_postprocessed.pdf";
  
  using (var img = Aspose.Imaging.Image.Load(filePath))
  {
    height += img.Height;
    width += img.Width;
  }

  var pdf = new Document();
  var pdfImageSection = pdf.Pages.Add();
  pdfImageSection.PageInfo.Width = width;
  pdfImageSection.PageInfo.Height = height;
  pdfImageSection.PageInfo.Margin.Bottom = 50;
  pdfImageSection.PageInfo.Margin.Top = 50;
  pdfImageSection.PageInfo.Margin.Right = 50;
  pdfImageSection.PageInfo.Margin.Left = 50;

  FileStream stream = new FileStream(filePath, FileMode.Open);
  var image = new Image { ImageStream = stream };

  pdfImageSection.Paragraphs.Add(image);

  pdf.Save(pdfFile);

While testing the scenario using 23.10 version of the API, we could not notice such an exception. Can you please try to test with the latest version and let us know in case you still notice any issues.

@amolm

Can you please try using Aspose.Pdf.Drawing instead of Aspose.PDF for .NET? Please uninstall existing Aspose.PDF package from your project and install Aspose.Pdf.Drawing instead from NuGet Package Manager. You would not need to change anything in the code. If issue still persists, please share complete environment details with us. We will log an investigation ticket and share the ID with you.
