Not able to generate image at Server side (C#)

[Ramesh Gujarathi]

Hi Team,

We are experiencing a issue, which was working fine till last month.

The issue is:

We send the Chart SVG information generated from Javascript to server side to save the image as png.  The code part of saving the image is not working properly.  The created image is always blank. No exceptions are thrown.

The Assemblies info:

• FusionCharts - 1.2.2.0
• SharpVectors.Converters 1.0.0.0
• SharpVectors.Rendering.Wpf 1.0.0.0
• SharpVectors.Runtime 1.0.0.0
• SharpVectors.Core 0.3.1.41457 

Please help us on this.

Here is the pice of the code:

private static MemoryStream GetJSImage(string svgHtml, string fileFormat)

{

          string type = fileFormat.ToString().ToLower(System.Globalization.CultureInfo.CurrentCulture);

          byte[] svg = Encoding.ASCII.GetBytes(svgHtml);

          WpfDrawingSettings ds = new WpfDrawingSettings();

           using (StreamSvgConverter ssc = new StreamSvgConverter(ds))

           {

                  ssc.SaveXaml = false;

                  ssc.SaveZaml = false;

 

                  ImageEncoderType encoder = ImageEncoderType.JpegBitmap;

                 switch (type)

                 {

                         case "png":

                                 encoder = ImageEncoderType.PngBitmap;

                                 break;

                        case "jpeg":

                                 encoder = ImageEncoderType.JpegBitmap;

                                 break;

                  }

                  ssc.EncoderType = encoder;

                  ssc.SaveXaml = false;

                 using (MemoryStream svgStream = new MemoryStream(svg))

                 {

                        TextReader svgData = new StreamReader(svgStream);

                        using (MemoryStream exportObjectStream = new MemoryStream())

                       {

                                 ssc.Convert(svgData, exportObjectStream);

                                return exportObjectStream;

                       }

                }

        }

}
