The ConvertTo Method is available as an add-on to the LEADTOOLS Document and Medical Imaging toolkits.
Returns this
LogicalRectangle structure, converted to its equivalent in the specified destination unit of measure.
Syntax
Visual Basic (Usage) | Copy Code |
---|
Dim instance As LogicalRectangle
Dim sourceDpiX As Double
Dim sourceDpiY As Double
Dim destinationUnit As LogicalUnit
Dim destinationDpiX As Double
Dim destinationDpiY As Double
Dim value As LogicalRectangle
value = instance.ConvertTo(sourceDpiX, sourceDpiY, destinationUnit, destinationDpiX, destinationDpiY) |
Parameters
- sourceDpiX
- Represents the DPI of the source value along the x-axis. This value is only used if the source unit of measure is Leadtools.Forms.LogicalUnit.Pixel.
- sourceDpiY
- Represents the DPI of the source value along the y-axis. This value is only used if the source unit of measure is Leadtools.Forms.LogicalUnit.Pixel.
- destinationUnit
- The unit of measurement of the destination value.
- destinationDpiX
- Represents the DPI of the destination value along the x-axis. This value is only used if the source unit of measure is Leadtools.Forms.LogicalUnit.Pixel.
- destinationDpiY
- Represents the DPI of the destination value along the y-axis. This value is only used if the source unit of measure is Leadtools.Forms.LogicalUnit.Pixel.
Example
This example creates a new LogicalRectangle structure in inches then converts it to another LogicalRectangle structure in pixels.

Private Sub LogicalRectangle_ConvertTo()
' create a new logical rectangle that is 1.5 2, 3, and 4 inches
Dim rect1 As LogicalRectangle = New LogicalRectangle(1.5f, 2f, 3f, 4f, LogicalUnit.Inch)
' show the rectangle
Dim s As String = String.Format("{0}", rect1)
MessageBox.Show(s)
' convert the rectangle to pixels
Dim rect2 As LogicalRectangle = rect1.ConvertTo(150, 150, LogicalUnit.Pixel, 150, 150)
' show
s = String.Format("{0}", rect2)
MessageBox.Show(s)
