IntersectRect

Description

Calculates the intersection of two source rectangles and places the coordinates of the intersection rectangle into the destination rectangle.

Syntax

BOOL IntersectRect( RECT * lprDst, const RECT * lprcSrc1, const RECT * lprcSrc2 )

Parameters

lprDst

[output] pointer to a RECT structure to receive the result

lprcSrc1

[input] first source RECT

lprcSrc2

[input] second source RECT

Return

If the rectangles intersect, returns TRUE.

If the rectangles do not intersect, returns FALSE.

Examples

EX1

void IntersectRect_Ex1()
{
        RECT recA = {10,20,40,50};
        RECT recB = {20,30,70,80};
        
        RECT rec ;
        if(IntersectRect(&rec,&recA,&recB))
        {
                printf("Intersection between recA and recB is:\n");
                printf("left:%d  top:%d  right:%d  bottom:  %d\n",rec.left,rec.top,rec.right,rec.bottom);        
        }
        else
                printf("recA and recB has no intersection\n");    
}

Remark

Calculates the intersection of two source rectangles and places the coordinates of the intersection rectangle into the destination rectangle.

If the source rectangles do not intersect, an empty rectangle (in which all coordinates are set to zero) is placed into the destination rectangle.
