Hi,

I'm using the RadChartView, but guess this issue relates to any control, so am posting here.

I'm using the ExportExtensions.ExportToImage to save the chart to disk. However, it's not exactly publication quality. Is there a way of increasing the resolution on export? I'll paste below the code I'm using.

Thanks, James.

 

SaveFileDialog dialog = new SaveFileDialog();
            dialog.DefaultExt = "*.png";
            dialog.Filter = "Files(*.png)|*.png";
            if (!(bool)dialog.ShowDialog())
                return;
            Telerik.Windows.Media.Imaging.PngBitmapEncoder enc = new Telerik.Windows.Media.Imaging.PngBitmapEncoder();
            using (Stream fileStream = dialog.OpenFile())
            {
                if (CircularGraphCrosstabs.Visibility == System.Windows.Visibility.Visible)
                    Telerik.Windows.Media.Imaging.ExportExtensions.ExportToImage(CircularGraphCrosstabs, fileStream, enc);
                else
                    Telerik.Windows.Media.Imaging.ExportExtensions.ExportToImage(GridCrosstabsChart, fileStream, enc);
            }

Hello James,

I would suggest you export the ChartView to PDF instead using our RadPdfProcessing API - please take a look at the ChartView Exporting online example at the following link:
http://demos.telerik.com/silverlight/#ChartView/Exporting
It gives the option to export the ChartView to PDF as well as PNG ( check the ComboBox on the left) - you can try both and compare the results. Indeed, using RadPdfProcessing requires additional coding, but it provides higher resolution of the exported ChartView.

Additionally, you could check the Document Processing Integration section inside the Export Support topic for more information and examples on the suggested approach.
