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. [C#] 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);
[VB] 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)
