hoa_video::ScreenRect Class Reference

A structure used for storing rectangles with pixel coordinates This class is used in storing the current scissoring rectangles, viewport rectangles, etc. It is based on standard screen coordinates, where (0,0) is the top-left and the unit is 1 pixel (hence int32 coordinates instead of floats).

Member Function Documentation

void hoa_video::ScreenRect::Intersect ( const ScreenRect & rect ) [inline]

Modifies the rectangle coordinates to be an intersection of itself with another rectangle.

Parameters:

rect

The rectangle to intersect this rectangle with The resulting intersection rectangle will have all its members set to zero if the two rectangles do not intersect. If the current rectangle has 100% intersection with the argument rectangle, no change in coordinates will occur. Typically, the intersection will be a smaller rectangle than the original two rectangles.
