Detailed Description

DRECT / FRECT

These rectangle classes are meant to be used for geographical areas, or texture coordinates, which assume that the vertical axis increases upward, not like typical screen coordinates which increase downwards.

This means that the Height() method returns top-bottom, not bottom-top as would be the case with downward-increasing coordinates.

bool DRECT::ContainsLine ( const DLine2 & line ) const

Fast, naive test for polyline/polygon inside rectangle.

Returns: true if any point of the poly is inside the rectangle.
