| double ClclDistSqrPntLine | ( | const a2dPoint2D & | p, |
| const a2dPoint2D & | p1, | ||
| const a2dPoint2D & | p2 | ||
| ) |
Calculate the square distance between a point and a line.
This returns DBL_MAX if the point is beyond the edges

| bool InArc | ( | double | angle, |
| double | start, | ||
| double | end, | ||
| bool | clockwise | ||
| ) |
is the angle within the arc segment taking into account drawing from start to end in clockwise or anti clocwise direction.
