Detailed Description

template<class T>
struct drain::Rectangle< T >

Rectange defined through lower left and upper right coordinates.

drain::Range<T>

Member Function Documentation

crop()

bool crop

(

const Rectangle< T > &

r

)

This becomes the intersection of r and this.

Two way bounds are needed, because cropping max can be lower than this min.

Returns

- true if rectangle was modified.
