VectorInt.ThresholdGT_LT Method

Overload List

#	Signature	Description
1	function ThresholdGT_LT(const GTLevel: Integer; const GTValue: Integer; const LTLevel: Integer; const LTValue: Integer): TMtxVecInt;	Threshold greater than and less than operation.
	└ indexed: function ThresholdGT_LT(const GTLevel: Integer; const GTValue: Integer; const LTLevel: Integer; const LTValue: Integer; Index: Integer; Len: Integer): TMtxVecInt;
2	function ThresholdGT_LT(const Vec: TMtxVecInt; const GTLevel: Integer; const GTValue: Integer; const LTLevel: Integer; const LTValue: Integer): TMtxVecInt;	Perform "greater than and less than" threshold operation on all Vec object values.
3	function ThresholdGT_LT(const Vec: TMtxVecInt; const GTLevel: Integer; const GTValue: Integer; const LTLevel: Integer; const LTValue: Integer; VecIndex: Integer; Index: Integer; Len: Integer): TMtxVecInt;	Perform "greater than and less than" threshold operation on Vec elements from range [VecIndex]..[VecIndex+Len-1].

Overload 1: function ThresholdGT_LT(const GTLevel: Integer; const GTValue: Integer; const LTLevel: Integer; const LTValue: Integer): TMtxVecInt;

Threshold greater than and less than operation.

#	Name	Type
1	GTLevel	Integer
2	GTValue	Integer
3	LTLevel	Integer
4	LTValue	Integer

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

Remarks:

Perform operation on all calling object values. The LTValue parameter is an lower bound for threshold operation. The GTValue parameter is an upper bound for threshold operation. All values less than LTLevel will be replaced with LTValue. All values bigger than GTLevel will be replaced with GTValue.

Examples

var a: TVecInt;
begin
    CreateIt(a);
    try
        a.SetIt([20,1,30,40]);
        a.ThresholdGT_LT(23,34,10,5); // a = [20,5,34,34]
    finally
        FreeIt(a);
    end;
end;

Indexed: function ThresholdGT_LT(const GTLevel: Integer; const GTValue: Integer; const LTLevel: Integer; const LTValue: Integer; Index: Integer; Len: Integer): TMtxVecInt;

Perfrom "greater than and less than" threshold operation on the calling object values in range [Index]..[Index+Len-1].

#	Name	Type	Description
1	GTLevel	Integer
2	GTValue	Integer
3	LTLevel	Integer
4	LTValue	Integer
5	Index	Integer	start index
6	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,[20,1,30,40]);
        a.ThresholdGT_LT(23,34,10,5); // a = [20,5,34,34]
    finally
        FreeIt(a);
    end;
end;

Overload 2: function ThresholdGT_LT(const Vec: TMtxVecInt; const GTLevel: Integer; const GTValue: Integer; const LTLevel: Integer; const LTValue: Integer): TMtxVecInt;

Perform "greater than and less than" threshold operation on all Vec object values.

#	Name	Type
1	Vec	TMtxVecInt
2	GTLevel	Integer
3	GTValue	Integer
4	LTLevel	Integer
5	LTValue	Integer

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

Remarks:

Store the results in calling object. Size of the calling object is adjusted automatically.

Overload 3: function ThresholdGT_LT(const Vec: TMtxVecInt; const GTLevel: Integer; const GTValue: Integer; const LTLevel: Integer; const LTValue: Integer; VecIndex: Integer; Index: Integer; Len: Integer): TMtxVecInt;

Perform "greater than and less than" threshold operation on Vec elements from range [VecIndex]..[VecIndex+Len-1].

#	Name	Type	Description
1	Vec	TMtxVecInt
2	GTLevel	Integer
3	GTValue	Integer
4	LTLevel	Integer
5	LTValue	Integer
6	VecIndex	Integer
7	Index	Integer	start index
8	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 of the calling object must be set explicitly. An exception is raised if TMtxVecBase.ConditionCheck is true and array borders are overrun/underrun.
