MagicWandRasterRegionData Constructor(LeadPoint,String,String)

public MagicWandRasterRegionData( 
   LeadPoint location,
   string lowerToleranceColor,
   string upperToleranceColor
)

'Declaration
 
Public Function New( _
   ByVal location As LeadPoint, _
   ByVal lowerToleranceColor As String, _
   ByVal upperToleranceColor As String _
)

'Usage
 
Dim location As LeadPoint
Dim lowerToleranceColor As String
Dim upperToleranceColor As String
 
Dim instance As New MagicWandRasterRegionData(location, lowerToleranceColor, upperToleranceColor)

public:
MagicWandRasterRegionData( 
   LeadPoint location,
   String^ lowerToleranceColor,
   String^ upperToleranceColor
)

Parameters

location

A point in an image with the color will be used to set the region.

lowerToleranceColor

Lower tolerance values that set the lower stopping point for the region.

upperToleranceColor

Upper tolerance values that set the upper stopping point for the region.

For gray scale bitmaps:

The minimum channel tolerance value of lowerToleranceColor will be used to set the lower stopping point, and the value of upperToleranceColor will be used to set the upper stopping point. For example, if the value of the pixel at (x, y) is (125, 125, 125) and lowerToleranceColor is (20,30,15), the smallest value of the triplet (15) will be used to create the lower stopping point of (110,110,110). If upperToleranceColor is (10,25,20), the smallest value of that triplet (10) will be used to create the upper stopping point of (135,135,135).

To update an existing region, specify how the new region is to be combined with the existing one using the RasterRegionData.CombineMode parameter. For more information, refer to RasterRegionCombineMode.
