Description
This function calculates the bounds of a given TPointArray TPA by searching the most outer coordinates of a box which can contain all of the points and returns that box as a TBox.
Example
var
TPA: TPointArray;
Box: TBox;
begin
TPA := [Point(0, 0), Point(2, 2), Point(5, 10)];
Box := TPABounds(TPA);
WriteLn('Box(' + IntToStr(Box.x1) + ',' + IntToStr(Box.y1) + ',' +
IntToStr(Box.x2) + ',' + IntToStr(Box.y2) + ')');
end.Output:
Box(0,0,5,10)
