C++

public float ConvertedLeft( 
   AnnUnitConverter converter,
   AnnUnit unit
)

'Declaration
 
Public Function ConvertedLeft( _
   ByVal converter As AnnUnitConverter, _
   ByVal unit As AnnUnit _
) As Single

'Usage
 
Dim instance As AnnRectangle
Dim converter As AnnUnitConverter
Dim unit As AnnUnit
Dim value As Single
 
value = instance.ConvertedLeft(converter, unit)

public:
float ConvertedLeft( 
   AnnUnitConverter^ converter,
   AnnUnit unit
)

Parameters

converter: The AnnUnitConverter object to be used in converting the value.
unit: Destination AnnUnit value indicating the unit of measure.

Return Value

A value for the left edge of this AnnRectangle structure, converted to its equivalent in the specified AnnUnit unit of measure.

The converter is used to do the actual conversion. If converter is null (Nothing in Visual Basic), the default AnnUnitConverter is used (in other words, conversion will be done based on the default 96 DPI).
