Exporting with Different Option

Exporting Diagram with Different Option:

Syncfusion® Diagram supports exporting diagrams with different options. To export a diagram in A4 size, we need to initialize the diagram accordingly with the A4 size.

The below code snippet shows how to initialize the diagram with the 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 a diagram with bounds where the node is available, you need to set `true` for the `SizeToContent` property and 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
