Exported Image is blurred

[Ciro]

Hi,

I have a problem with the "Export to image"  feature of the RadDiagram.
In particular when I export an image with lots of RadDiagramShape and RadDiagramConnections the image has a  correct dimension, but the shapes and the connections are blurred. 

The following is the piece of code which I use to  serialize the image and I' ve attached  an example of exported image.

using (var rawImageStream = new MemoryStream())            {
                diagram.ExportToImage(rawImageStream, margin: ExportMargin, backgroundBrush: new SolidColorBrush(Colors.White));
                rawImageStream.Seek(0, SeekOrigin.Begin);

                using (var trimmedBitmap = new Bitmap(rawImageStream).Trim(0xffffff)) {
                    trimmedBitmap.Save(outputStream, ImageFormat.Png);
                }
  }

Is there a way to improve it and render the exported image clearer?
Thanks

Ciro

Hi Ciro,

You can increase the DPI when exporting Image in RadDiagram. The default setting is 96 dpi. You can use an optional parameter in the ExportToImage method:

public void ExportToImage(Stream stream, BitmapEncoder encoder = null, Rect? enclosingBounds = null, Size returnImageSize = new Size(), Brush backgroundBrush = null, Thickness margin = new Thickness(), double dpi = RadDiagramPrintSettings.DefaultDpi)

Hello,

I have the same problem as Ciro.
The larger the diagram is, the blurrier it gets. Increasing the dpi does not fix the problem, it only increases the dimensions of the exported image.
Is there another way to improve it ?

Thanks

While using ExportToImage, I dnt want the focused element to come in the image generated. How can I do that?

I had the same problem of Aakansha. My solution was to memorize the selected shapes, then unselect all selected shapes, export to image and finally select the stored shapes again. I hope this help.

Hello Ciro,

I didnt understand how will I implement that? Can you share some code snippet implementing this, if possible? That will help me get the clarity.
