channel
The channel for which to get the information. This value is ignored if the image is 12 or 16-bit grayscale.
start
Indicates the beginning color value of the range for the evaluation. This property only accepts positive values.
end
Indicates the ending color value of the range for the evaluation. This property only accepts positive values.
Initializes a new StatisticsInformationCommand with explicit parameters.

Syntax

Visual Basic (Declaration) 
Public Function New( _
