The AddLine method uses the following syntax:
.AddLine(BeginX, BeginY, EndX, EndY)
: The data type for all AddLine parameters is single.
AddLine Parameters
The AddLine method has four parameters:
|
BeginX |
The X coordinate (in points) for the starting point of the line. The coordinate is relative to the top left corner of the slide. |
|
BeginY |
The Y coordinate (in points) for the starting point of the line. The coordinate is relative to the top left corner of the slide. |
|
EndX |
The X coordinate (in points) for the ending point of theline. The position is relative to the bottom left corner of the slide. |
|
EndY |
The Y coordinate (in points) for the ending point of the line. The position is relative to the bottom left corner of the slide. |
Creating Lines
The following sample Visual Basic procedure draws a horizontal line across
the middle of the first slide in a presentation.
Sub DrawHorizontalLine()
Dim longHeight As Long
Dim longWidth As Long
' Get the slide height and width.
longHeight = ActivePresentation.PageSetup.SlideHeight
longWidth = ActivePresentation.PageSetup.SlideWidth
With ActivePresentation.Slides(1).Shapes
' Create the line.
.AddLine 0, (longHeight \ 2), longWidth, (longHeight \ 2)
End With
End Sub
The following sample Visual Basic procedure draws a vertical line down the
middle of the first slide in a presentation.
Sub DrawVerticalLine()
Dim longHeight As Long
Dim longWidth As Long
' Get the slide height and width.
longHeight = ActivePresentation.PageSetup.SlideHeight
longWidth = ActivePresentation.PageSetup.SlideWidth
With ActivePresentation.Slides(1).Shapes
' Create the line.
.AddLine (longWidth \ 2), 0, (longWidth \ 2), longHeight
End With
End Sub
The following sample Visual Basic procedure draws two diagonal lines. The
diagonal lines form an X on the first slide in a presentation.
Sub DrawDiagonalLines()
Dim longHeight As Long
Dim longWidth As Long
' Get the slide height and width.
longHeight = ActivePresentation.PageSetup.SlideHeight
longWidth = ActivePresentation.PageSetup.SlideWidth
With ActivePresentation.Slides(1).Shapes
' Create line from top left to bottom right.
.AddLine 0, 0, longWidth, longHeight
' Create line from top right to bottom left.
.AddLine longWidth, 0, 0, longHeight
End With
End Sub
Using the Return Value
The AddLine method returns a reference to a shape that you created. You can
use the reference to modify the properties of the line.
The following sample Visual Basic procedure uses the return value to change
the line color and weight.
Sub ChangeLineColor()
Dim longHeight As Long
Dim longWidth As Long
Dim MyLine As Shape
' Get the slide height and width.
longHeight = ActivePresentation.PageSetup.SlideHeight
longWidth = ActivePresentation.PageSetup.SlideWidth
With ActivePresentation.Slides(1).Shapes
' Get the return value and create the line.
Set MyLine = .AddLine(100, 100, 300, 100)
' Change line weight to 50 point.
MyLine.Line.Weight = 50
' Change line color to red.
MyLine.Line.ForeColor.RGB = RGB(255, 0, 0)
End With
End Sub
NOTE: Because the AddLine method returns an object, use the Set command to get the returned shape reference.
