Detailed Description

A round rectangle shape, based on a rectangle and a radius.

For now, not an inheritor of SHAPE as that means implementing a lot of Collision logic. Then again, this is a common shape, could be more efficient to do the collision using arcs rather than Clipper'ing pad outsets.

Member Function Documentation

BBox()

BOX2I ROUNDRECT::BBox ( ) const

inline

Get the bounding box of the roundrect.

(This is always the same as the basis rectangle's bounding box.)

GetInflated()

ROUNDRECT ROUNDRECT::GetInflated

(

int

aOutset

)

const

Get the roundrect with the size increased by aOutset in all directions.

(the radius increases by aOutset as well).

Get the basis rectangle of the roundrect.

This is the rectangle without the rounded corners.
