Property Value

Type: System.Single
Returns a Single.

Remarks

You can use the ScaleHeight and ScaleWidth properties to create a custom coordinate scale for drawing or printing. For example, the statement ScaleHeight = 100 changes the units of measurement of the height of the page. Instead of the height being some number of current units (twips or pixels, for example), the height will be 100 user-defined units. Therefore, a distance of 50 units is half the height of the page, and a distance of 101 units will exceed the boundaries of the page by 1 unit.

Use the ScaleMode property to define a scale based on a standard unit of measurement, such as twips, points, pixels, characters, inches, millimeters, or centimeters.

Setting the ScaleHeight and ScaleWidth properties to positive values makes coordinates increase from top to bottom and left to right. Setting them to negative values makes coordinates increase from bottom to top and right to left.

By using these properties and the related ScaleLeft and ScaleTop properties, you can create a coordinate system with both positive and negative coordinates. All four of these scale properties interact with the ScaleMode property in the following ways:

• Setting another scale property to any value automatically sets ScaleMode to 0. A ScaleMode of 0 is user-defined.

• Setting ScaleMode to a number larger than 0 changes ScaleHeight and ScaleWidth to the new unit of measurement and sets ScaleLeft and ScaleTop to 0. In addition, the CurrentX and CurrentY settings change to reflect the new coordinates of the current point.

You can also use the Scale method to set the ScaleHeight, ScaleWidth, ScaleLeft, and ScaleTop properties in one statement.

Examples

The following example demonstrates how to set the ScaleHeight and ScaleWidth properties.

Dim Printer As New Printer
Dim Radius As Integer
Printer.ScaleHeight = 100
Printer.ScaleWidth = 100
Printer.FillStyle = 1
For Radius = 5 To 50 Step 5
    Printer.Circle(50, 50, Radius)
Next Radius
Printer.EndDoc()
