Saving a part of a diagram to image format:

Syncfusion diagram supports saving a part of a diagram in image format. To achieve this requirement invoke the Diagram’s ExportDiagramToGraphics method with desired area and Graphics class object as an argument.

The below code snippet shows how to select a part of diagram and exporting it in image format.


Image img = null;
Graphics gfx;
RectangleF rectBounding = RectangleF.Empty;
gfx = Graphics.FromImage(img);
//selecting desired area from the diagram
rectBounding = new RectangleF(100,100,500,500);
this.diagram1.ExportDiagramToGraphics(gfx, rectBounding);
//saving the diagram in image format
Bitmap bmp = (Bitmap)img;
bmp.Save(strFileName, ImageFormat.Png);



Dim img As Image = Nothing
Dim gfx As Graphics
Dim rectBounding As RectangleF = RectangleF.Empty
gfx = Graphics.FromImage(img)
'selecting desired area from the diagram
rectBounding = New RectangleF(100,100,500,500)
Me.diagram1.ExportDiagramToGraphics(gfx, rectBounding)
'saving the diagram in image format
Dim bmp As Bitmap = CType(img, Bitmap)
bmp.Save(strFileName, ImageFormat.Png)
