Syntax

public void InitializeGaussianBlur(
	int numberOfSamples,
	float standardDeviation,
	bool useHardwareFiltering
)

Public Sub InitializeGaussianBlur ( 
	numberOfSamples As Integer,
	standardDeviation As Single,
	useHardwareFiltering As Boolean
)

public:
void InitializeGaussianBlur(
	int numberOfSamples, 
	float standardDeviation, 
	bool useHardwareFiltering
)

member InitializeGaussianBlur : 
        numberOfSamples : int * 
        standardDeviation : float32 * 
        useHardwareFiltering : bool -> unit

numberOfSamples: Type: SystemInt32
The number of samples. This value must be an odd number (e.g. 3, 5, 7, ...).
standardDeviation: Type: SystemSingle
The standard deviation.
useHardwareFiltering: Type: SystemBoolean
If set to hardware filtering is used to increase the blur effect; otherwise, hardware filtering is not used. Use if you are filtering floating-point textures.

Exceptions

Exception	Condition
ArgumentOutOfRangeException	numberOfSamples is zero or negative.
ArgumentException	numberOfSamples is an even number. A Gaussian blur requires an odd number of samples.
