	BitmapData image,
	Rectangle rect
)

Public Function CalculateThreshold ( 
	image As BitmapData,
	rect As Rectangle
) As Integer

image: Type: System.Drawing.ImagingBitmapData
Image to calculate binarization threshold for.
rect: Type: System.DrawingRectangle
Rectangle to calculate binarization threshold for.

Type: Int32
Returns binarization threshold.

Exceptions

Exception	Condition
UnsupportedImageFormatException	Source pixel format is not supported by the routine. It should be 8 bpp grayscale (indexed) image.
