function TPAFromBox(const Box: TBox): TPointArray;

Availability

SCAR Divi 3.26 > Current

Notes

  • Before 3.39, the function did not throw an exception on an invalid box.

Description

Generates a TPointArray containing all coordinates within the given TBox Box. The coordinates are stored row-by-row in the TPointArray. If Box is invalid (XE > XS and/or YE > XS), the function throws an exception.

Example

begin
  WriteLn('TPointArray[' + TPAToStr(TPAFromBox(Box(3, 1, 5, 5))) + ']');
end.

Output:

TPointArray[(3,1);(4,1);(3,2);(4,2);(3,3);(4,3);(3,4);(4,4)]
