Example

This example shows how to convert between AnnUnit and AnnAngularUnit in several ways.

using Leadtools; 
using Leadtools.Annotations; 
 
private void AnnUnitConverter_AnnUnitConverter() 
{ 
   // set up the unit converter with 96 DPI 
   AnnUnitConverter converter = new AnnUnitConverter(96, 96); 
 
   // 200 pixels 
   float pixels = 200; 
 
   // convert to inches 
   float inches = converter.ConvertHorizontal(pixels, AnnUnit.Pixel, AnnUnit.Inch); 
 
   // show 
   string s = string.Format("{0} {1} is {2} {3} at {4} DPI", 
      pixels, 
      AnnUnitConverter.GetUnitAbbreviation(AnnUnit.Pixel), 
      inches, 
      AnnUnitConverter.GetUnitAbbreviation(AnnUnit.Inch), 
      converter.DpiX); 
   MessageBox.Show(s); 
 
   // 45 degrees 
   float degrees = 45; 
 
   // convert to radians 
   float radians = AnnUnitConverter.Convert(degrees, AnnAngularUnit.Degree, AnnAngularUnit.Radian); 
 
   // show 
   s = string.Format("{0}{1} is {2} {3}", 
      degrees, 
      AnnUnitConverter.GetAngularUnitAbbreviation(AnnAngularUnit.Degree), 
      radians, 
      AnnUnitConverter.GetAngularUnitAbbreviation(AnnAngularUnit.Radian)); 
   MessageBox.Show(s); 
}
