Example

This example sets up a unit converter class with different horizontal and vertical DPI values and then converts horizontal and vertical values from pixels to inches.

Visual BasicCopy Code
Public Sub AnnUnitConverter_ConvertHorizontal()
   ' set up a new unit converter with 96 horizontal and 192 vertical DPI
   Dim converter As AnnUnitConverter = New AnnUnitConverter(96, 192)
   Dim pixels As Single = 200

   ' convert using the horizontal DPI
   Dim horzInches As Single = converter.ConvertHorizontal(200, AnnUnit.Pixel, AnnUnit.Inch)

   ' convert using the vertical DPI
   Dim vertInches As Single = converter.ConvertVertical(200, AnnUnit.Pixel, AnnUnit.Inch)

   ' show
   Dim s As String = String.Format("{0} {1} is {2} {3} at {4} X DPI{5}{0} {1} is {6} {3} at {7} Y DPI", pixels, AnnUnitConverter.GetUnitAbbreviation(AnnUnit.Pixel), horzInches, AnnUnitConverter.GetUnitAbbreviation(AnnUnit.Inch), converter.DpiX, Environment.NewLine, vertInches, converter.DpiY)
   MessageBox.Show(s)
End Sub
