function TPAInTPARelEx(const TPA1, TPA2: TPointArray; var TPAFound: TPointArray): Boolean;
Availability
SCAR Divi 3.28 > Current
Description
Returns true if a series of points are found in TPA2 that are all at the same relative position towards eachother as the points in TPA1. The points from TPA2 that are equivalent to the first point in TPA1 are returned in TPAFound. The function does not take into account duplicate points. If your arrays contain a lot of duplicate points, the overall execution time will be shorter is you remove the duplicate points first with TPARemoveDupl.
Example
var TPA1, TPA2, TPA: TPointArray; begin TPA1 := [Point(2, 5), Point(6, 1), Point(1, 1)]; TPA2 := [Point(4, 7), Point(8, 3), Point(3, 3)]; WriteLn(TPAInTPARelEx(TPA1, TPA2, TPA)); WriteLn(TPAToStr(TPA)); TPA1 := [Point(2, 5), Point(6, 1), Point(1, 1)]; TPA2 := [Point(0, 0), Point(4, 7), Point(1, 1), Point(8, 3), Point(3, 3)]; WriteLn(TPAInTPARelEx(TPA1, TPA2, TPA)); WriteLn(TPAToStr(TPA)); TPA1 := [Point(1, 5), Point(6, 1), Point(1, 1)]; TPA2 := [Point(0, 0), Point(4, 7), Point(1, 1), Point(8, 3), Point(3, 3)]; WriteLn(TPAInTPARelEx(TPA1, TPA2, TPA)); WriteLn(TPAToStr(TPA)); end.
Output:
1 (4,7) 1 (4,7) 0
