Public Function CreateBitmap () As Long

C++  Copy Code
public: unsigned int CreateBitmap ()

 Return Value

The method creates a GDI bitmap and draws the current diagram in the bitmap. Only a portion of the diagram can be drawn, by specifying rectangle coordinates via the ImageExportOptions property. That property also exposes a scaling factor to be used when drawing the diagram contents in the image. The created bitmap could be used to display overview of a diagram, or to export diagram to an image file.

The following sample shows how to export a jpeg file. The BmgLib library is used for jpeg creation, together with a wrapper COM object for that library that makes its use within VB easier:

Private Sub Command1_Click()     Dim exporter As New BmgLib     exporter.JpegQuality = 80     exporter.SaveBitmapToFile flowchart1.CreateBitmap, "C:\test.jpg", True End Sub
