Exporting Diagram with Different Option:

Syncfusion Diagram supports exporting diagram with different options. To Export a diagram in A4 size we need to initialize the diagram respective with the A4 size.

The below code snippet shows how to initialize the diagram with desired A4 size.

[C#]

var sizeA4 = new PaperSize();
sizeA4.RawKind = PaperKind.A4;
//Initializing Diagram’s size.
diagram1.Size = new Size(sizeA4.Width, sizeA4.Height);

[VB]

Dim sizeA4 = New PaperSize()
sizeA4.RawKind = PaperKind.A4
‘Initializing Diagram’s size.
diagram1.Size = New Size(sizeA4.Width, sizeA4.Height)

To export diagram with bounds where the node is available means need to set true for the SizeToContent property and need to set false for the BoundaryConstraintsEnabled property.

The below code shows how to export the diagram based on the bounds where the node is available.

[C#]

diagram1.Model.BoundaryConstraintsEnabled = false;
diagram1.Model.SizeToContent = true;

[VB]

diagram1.Model.BoundaryConstraintsEnabled = False
diagram1.Model.SizeToContent = True

To export diagram in image format the SaveFileDialog must be initialized and required image format must be passed as an argument.

The below code snippet show how to export the diagram in image format.

[C#]

SaveFileDialog saveFileDialog1 = new SaveFileDialog();
if (saveFileDialog1.ShowDialog() == System.Windows.Forms.DialogResult.OK)
             {
//To Export the diagram in PNG format
ImageFormat imgformat = ImageFormat.Png;
Image img = this.diagram1.View.ExportDiagramAsImage(false);
img.Save(saveFileDialog1.FileName, imgformat);
   }

[VB]

Dim saveFileDialog1 As New SaveFileDialog()
            If saveFileDialog1.ShowDialog() = System.Windows.Forms.DialogResult.OK Then
              ‘To Export the diagram in PNG format
                Dim imgformat As ImageFormat = ImageFormat.Png
                Dim img As Image = Me.diagram1.View.ExportDiagramAsImage(False)
                img.Save(saveFileDialog1.FileName, imgformat)
            End If
