VectorInt.ThreshBottom Method

Overload List

#	Signature	Description
1	function ThreshBottom(const Src: TMtxVecInt; const Value: Integer): TMtxVecInt;	Perform threshold operation on all Src object values.
	└ indexed: function ThreshBottom(const Vec: TMtxVecInt; const Value: Integer; VecIndex: Integer; Index: Integer; Len: Integer): TMtxVecInt;
2	function ThreshBottom(const Value: Integer): TMtxVecInt;	Threshold bottom operation.
	└ indexed: function ThreshBottom(const Value: Integer; Index: Integer; Len: Integer): TMtxVecInt;

Overload 1: function ThreshBottom(const Src: TMtxVecInt; const Value: Integer): TMtxVecInt;

Perform threshold operation on all Src object values.

#	Name	Type	Description
1	Src	TMtxVecInt
2	Value	Integer

Result: stored in self (calling object), returns self for chaining

Remarks:

Store the results in calling object. Size and VectorInt.IntPrecision properties of the calling object are adjusted automatically.

Indexed: function ThreshBottom(const Vec: TMtxVecInt; const Value: Integer; VecIndex: Integer; Index: Integer; Len: Integer): TMtxVecInt;

Perform a threshold operation on Vec elements [VecIndex]..[VecIndex+Len-1].

#	Name	Type	Description
1	Vec	TMtxVecInt
2	Value	Integer
3	VecIndex	Integer
4	Index	Integer	start index
5	Len	Integer	element count

Result: stored in self (calling object), returns self for chaining

Remarks:

Store the results in the calling object elements [Index]..[Index+Len-1]. Size and VectorInt.IntPrecision properties of the calling object must be set explicitly. An exception is raised if TMtxVecBase.ConditionCheck is true and array borders are overrun/underrun.

Overload 2: function ThreshBottom(const Value: Integer): TMtxVecInt;

Threshold bottom operation.

#	Name	Type	Description
1	Value	Integer

Result: stored in self (calling object), returns self for chaining

Remarks:

Perform threshold operation on all calling object values. The Value parameter is a lower bound for threshold operation. All values smaller than Value will be replaced with Value.

Examples

var a: TVecInt;
begin
    CreateIt(a);
    try
        a.SetIt([2,0,3,4]);
        a.ThreshBottom(1); // a = [2,1,3,4]
    finally
        FreeIt(a);
    end;
end;

Indexed: function ThreshBottom(const Value: Integer; Index: Integer; Len: Integer): TMtxVecInt;

Perform the threshold operation on calling object values [Index]..[Index+Len-1].

#	Name	Type	Description
1	Value	Integer
2	Index	Integer	start index
3	Len	Integer	element count

Result: stored in self (calling object), returns self for chaining

Remarks:

An exception is raised if array borders are overrun/underrun.

Examples

var a: TMtxInt;
begin
    CreateIt(a);
    try
        a.SetIt(2,2,[2,0,3,4]);
        a.ThreshBottom(1); // a = [2,1,3,4]
    finally
        FreeIt(a);
    end;
end;
