Member Function Documentation

Intersect() [1/2]

static IntRect libCZI::IntRect::Intersect ( const IntRect &  a, const IntRect &  b  )

inlinestatic

Calculate the intersection of the two specified rectangle.

Parameters

a	The first rectangle.
b	The second rectangle.

Returns

A rectangle which is the intersection of the two rectangles. If the two rectangles do not intersect, an empty rectangle is returned (width=height=0).

Intersect() [2/2]

IntRect libCZI::IntRect::Intersect ( const IntRect &  r ) const

inline

Calculate the intersection with the specified rectangle.

Parameters

r	The rectangle for which the intersection is to be calculated.

Returns

A rectangle which is the intersection of the two rectangles. If the two rectangles do not intersect, an empty rectangle is returned (width=height=0).

IntersectsWith()

bool libCZI::IntRect::IntersectsWith ( const IntRect &  r ) const

inline

Determine whether this rectangle intersects with the specified one.

Parameters

r	The other rectangle.

Returns

True if the two rectangles intersect, false otherwise.
