	intersect (Region *source2) : none Sets the area of source1 to the intersection of the areas of source1 and source2. Sets the area of source1 to the intersection of the areas of source1 and source2. The resulting area is the set of pixels contained in both source1 and source2. Parameters: Gdk.Region source2* Required (not null) Returns: none	Gdk.Region
	offset (Number dx, Number dy) : none Moves a region the specified distance. Moves a region the specified distance. Parameters: Number dx Required (not null) Number dy Required (not null) Returns: none	Gdk.Region
	point_in (Number x, Number y) : Boolean Finds out if a point is in a region. Finds out if a point is in a region. Parameters: Number x Required (not null) Number y Required (not null) Returns: Boolean	Gdk.Region
	rect_equal (Rectangle *rectangle) : Boolean Finds out if a regions is the same as a rectangle. Finds out if a regions is the same as a rectangle. Parameters: Gdk.Rectangle rectangle* Required (not null) Returns: Boolean	Gdk.Region
	rect_in (Rectangle *rectangle) : Gdk.OverlapType Tests whether a rectangle is within a region. Tests whether a rectangle is within a region. GDK_OVERLAP_RECTANGLE_PART, depending on whether the rectangle is inside, outside, or partly inside the GdkRegion, respectively. Parameters: Gdk.Rectangle rectangle* Required (not null) Returns: Gdk.OverlapType	Gdk.Region
	shrink (Number dx, Number dy) : none Resizes a region by the specified amount. Resizes a region by the specified amount. Positive values shrink the region. Negative values expand it. Parameters: Number dx Required (not null) Number dy Required (not null) Returns: none	Gdk.Region
	spans_intersect_foreach (Span *spans, Number n_spans, Boolean sorted, Function function, void *data) : none Calls a function on each span in the intersection of region* and spans. Calls a function on each span in the intersection of region and spans. Parameters: Gdk.Span spans Required (not null) Number n_spans Required (not null) Boolean sorted Required (not null) Function (Span *span, void *data) : none Required (not null) void data Required (not null) Returns: none	Gdk.Region
	subtract (Region *source2) : none Subtracts the area of source2 from the area source1. Subtracts the area of source2 from the area source1. The resulting area is the set of pixels contained in source1 but not in source2. Parameters: Gdk.Region source2* Required (not null) Returns: none	Gdk.Region
	union (Region *source2) : none Sets the area of source1 to the union of the areas of source1 and either source1 or source2. Sets the area of source1 to the union of the areas of source1 and either source1 or source2. Parameters: Gdk.Region source2* Required (not null) Returns: none	Gdk.Region
	union_with_rect (Rectangle *rect) : none Sets the area of region* to the union of the areas of region and either region or rect. Sets the area of region to the union of the areas of region and either region or rect. Parameters: Gdk.Rectangle rect Required (not null) Returns: none	Gdk.Region
	xor (Region *source2) : none Sets the area of source1 to the exclusive-OR of the areas of source1 and source2. Sets the area of source1 to the exclusive-OR of the areas of source1 and source2. The resulting area is the set of pixels contained in one or the other of the two sources but not in both. Parameters: Gdk.Region source2* Required (not null) Returns: none	Gdk.Region
