  We are receiving the following error.

  Image is not created or loaded into a GcBitmap. at GrapeCity.Documents.Imaging.GcBitmap.SetDpi(Single dpiX, Single dpiY)
  
  

              
              using (var gchtml = new GcHtmlRenderer(html))
              {
                  using (GcBitmap b = new GcBitmap())
                  {
                      gchtml.RenderToGcBitmap(b, new HtmlToImageFormat(true, true)
                      {
                          WindowSize = new Size(414, 896), // size of browser window
                          DefaultBackgroundColor = Color.Empty, // this will be inferred from the HTML
                          MaxLeftMargin = 125,
                          MaxRightMargin = 125
                      });
  
                      b.SetDpi(300); // default resize pixel width and height is proportionate to 300DPI taken from google page found
  
                      using (var resizedBitmap = Resize(b, new Size(650, 5610)))
                      {
                          resizedBitmap.SaveAsPng(filePath);
                      }
                  }
              }
  
  

  The contents of the html variable is attached

  Hello Richard,

  Sorry, we do not face the issue with the attached HTML file in your support query.
  
  We do not see any Resize method in your given code snippet so we used the above given stripped-down code by removing Resize method call but the HTML file is saved successfully to PNG. Please find the attached sample implementing the same.

  If you are doing anything else then please modify the sample accordingly so that we can replicate the issue at our end and assist you better.

  regards,
  
  Prabhat Sharma.
