Methods

Equals(EdgeDetectorKernel)

Indicates whether the current object is equal to another object of the same type.

Declaration

public bool Equals(EdgeDetectorKernel other)

Parameters

Type	Name	Description
EdgeDetectorKernel	other	An object to compare with this object.

Returns

Type	Description
bool	true if the current object is equal to the other parameter; otherwise, false.

Equals(object?)

Indicates whether this instance and a specified object are equal.

Declaration

public override bool Equals(object? obj)

Parameters

Type	Name	Description
object	obj	The object to compare with the current instance.

Returns

Type	Description
bool	true if obj and this instance are the same type and represent the same value; otherwise, false.

Overrides

ValueType.Equals(object)

GetHashCode()

Returns the hash code for this instance.

Declaration

public override int GetHashCode()

Returns

Type	Description
int	A 32-bit signed integer that is the hash code for this instance.

Overrides

ValueType.GetHashCode()

Operators

operator ==(EdgeDetectorKernel, EdgeDetectorKernel)

Checks whether two EdgeDetectorKernel structures are equal.

Declaration

public static bool operator ==(EdgeDetectorKernel left, EdgeDetectorKernel right)

Parameters

Type	Name	Description
EdgeDetectorKernel	left	The left hand EdgeDetectorKernel operand.
EdgeDetectorKernel	right	The right hand EdgeDetectorKernel operand.

Returns

Type	Description
bool	True if the left parameter is equal to the right parameter; otherwise, false.

operator !=(EdgeDetectorKernel, EdgeDetectorKernel)

Checks whether two EdgeDetectorKernel structures are equal.

Declaration
