Public Property PageScale As Single

Property Value

Type: System.Single

This property specifies a value for the scaling between world units and page units for this Graphics.

The following code example demonstrates how to use the PageScale and TranslateTransform members to change the scale and origin when you draw a rectangle.

This example is designed to be used with Windows Forms. Paste the code into a form and call the ChangePageScaleAndTranslateTransform method when handling the form's Paint event, passing e as PaintEventArgs.

Private Sub ChangePageScaleAndTranslateTransform(ByVal e As _

    ' Create a rectangle.
    Dim rectangle1 As New Rectangle(20, 20, 50, 100)

    ' Draw its outline.
    e.Graphics.DrawRectangle(Pens.SlateBlue, rectangle1)

    ' Change the page scale.  
    e.Graphics.PageScale = 2.0F

    ' Call TranslateTransform to change the origin of the
    '  Graphics object.
    e.Graphics.TranslateTransform(10.0F, 10.0F)

    ' Draw the rectangle again.
    e.Graphics.DrawRectangle(Pens.Tomato, rectangle1)

    ' Set the page scale and origin back to their original values.
    e.Graphics.PageScale = 1.0F

    Dim transparentBrush As New SolidBrush(Color.FromArgb(50, Color.Yellow))

    ' Create a new rectangle with the coordinates you expect
    ' after setting PageScale and calling TranslateTransform:
    ' x = (10 + 20) * 2
    ' y = (10 + 20) * 2
    ' Width = 50 * 2
    ' Length = 100 * 2
    Dim newRectangle As Rectangle = New Rectangle(60, 60, 100, 200)

    ' Fill in the rectangle with a semi-transparent color.
    e.Graphics.FillRectangle(transparentBrush, newRectangle)
End Sub
