Essential diagram allows to export the diagram to word document and to image.

  • Exporting as Image can be achieved by using Diagram.ExportDiagramAsImage() and saving as Image.
  • Exporting into Word document can be achieved by saving the diagram in standard image formats such as bitmaps, enhanced metafiles , SVG format files and these images can be exported to word document using Essential DocIO. For this it is neccessary to have Essential DocIO to be installed.

Exporting as Image

C#

ImageFormat imgformat = ImageFormat.Bmp;

Image img = this.diagram1.View.ExportDiagramAsImage(true);

img.Save("MyDiagram.bmp", imgformat);

VB

Dim imgformat As ImageFormat = ImageFormat.Bmp

Dim img As Image = Me.diagram1.View.ExportDiagramAsImage(True)

img.Save("MyDiagram.bmp", imgformat)

Exporting into Word Document

C#

System.Drawing.Image diagramimage = new Bitmap(1, 1, PixelFormat.Format24bppRgb);

Graphics grfx = Graphics.FromImage(diagramimage);

IntPtr hdc = grfx.GetHdc();

Metafile emf = new Metafile(hdc, EmfType.EmfOnly);

Graphics emfgrfx = Graphics.FromImage(emf);

this.diagram1.View.ExportDiagramToGraphics(emfgrfx,true);

grfx.ReleaseHdc(hdc);

grfx.Dispose();

emfgrfx.Dispose();

diagramimage.Dispose();

WordDocument document = new WordDocument();

//Adding a new section to the document.

IWSection section = document.AddSection();

//Adding a paragraph to the section

IWParagraph paragraph = section.AddParagraph();

WPicture mImage = (WPicture)paragraph.AppendPicture(emf);

document.Save("Sample.doc", Syncfusion.DocIO.FormatType.Doc);

System.Diagnostics.Process.Start("Sample.doc");

VB

Dim diagramimage As System.Drawing.Image = New Bitmap(1, 1, PixelFormat.Format24bppRgb)

Dim grfx As Graphics = Graphics.FromImage(diagramimage)

Dim hdc As IntPtr = grfx.GetHdc()

Dim emf As Metafile = New Metafile(hdc, EmfType.EmfOnly)

Dim emfgrfx As Graphics = Graphics.FromImage(emf)

Me.diagram1.View.ExportDiagramToGraphics(emfgrfx,True)

grfx.ReleaseHdc(hdc)

grfx.Dispose()

emfgrfx.Dispose()

diagramimage.Dispose()

Dim document As WordDocument = New WordDocument()

'Adding a new section to the document.

Dim section As IWSection = document.AddSection()

'Adding a paragraph to the section

Dim paragraph As IWParagraph = section.AddParagraph()

Dim mImage As WPicture = CType(paragraph.AppendPicture(emf), WPicture)

document.Save("Sample.doc", Syncfusion.DocIO.FormatType.Doc)

System.Diagnostics.Process.Start("Sample.doc")
