int IntersectClipRect( int x1, int y1, int x2, int y2 );
int IntersectClipRect( LPRECT lpRect );
x1
Specifies the logical x-coordinate of the upper-left corner of the rectangle.
y1
Specifies the logical y-coordinate of the upper-left corner of the rectangle.
x2
Specifies the logical x-coordinate of the lower-right corner of the rectangle.
y2
Specifies the logical y-coordinate of the lower-right corner of the rectangle.
lpRect
Specifies the rectangle. You can pass either a CRect object or a pointer to a RECT structure for this parameter.
Creates a new clipping region by forming the intersection of the current region and the rectangle specified by x1, y1, x2, and y2. GDI clips all subsequent output to fit within the new boundary.
The new clipping region's type. It can be any one of the following values:
Value | Meaning |
COMPLEXREGION | New clipping region has overlapping borders. |
ERROR | Device context is not valid. |
NULLREGION | New clipping region is empty. |
SIMPLEREGION | New clipping region has no overlapping borders. |
