Member Function Documentation

getPoint()

Vector2f gf::Pie::getPoint ( std::size_t  index ) const

overridevirtual

Get a point of the shape.

The returned point is in local coordinates, that is, the shape's transforms (position, rotation, scale) are not taken into account.

The result is undefined if index is out of the valid range.

Parameters

index

Index of the point to get, in range \( [0, n-1] \) where \( n \) is the number of points of the shape.

Returns

index-th point of the shape

See also

getPointCount()

Implements gf::Shape.

getPointCount()

std::size_t gf::Pie::getPointCount ( ) const

overridevirtual

Get the total number of points of the shape.

Returns

Number of points of the shape
