Enumeration Type Documentation

RangeKind

enum gnash::geometry::RangeKind

Kinds of a range.

Enumerator
finiteRange	Valid range, using finite values.
nullRange	A NULL range is a range enclosing NO points.
worldRange	A WORLD range2d is a range including all points on the plane. Note that scaling, shifting and unioning will NOT change a WORLD range.

Function Documentation

Intersect()

template<typename T >

bool gnash::geometry::Intersect ( const Range2d< T > &  r1, const Range2d< T > &  r2  )

inline

Return true of the two ranges intersect (boundaries included)

References gnash::geometry::Range2d< T >::intersects().

Intersection()

template<typename T >

Range2d<T> gnash::geometry::Intersection ( const Range2d< T > &  r1, const Range2d< T > &  r2  )

inline

Return a rectangle being the intersetion of the two rectangles.

Any NULL operand will make the result also NULL.
