Detailed Description

A GdkRegion C++ wrapper interface.

Provides Region, an object that holds a set of arbitrary pixels, and is usually used for clipping graphical operations (see Gdk::GC::set_clip_region()).

Enumeration Type Documentation

enum FillRule

Specifies the method for determining which pixels are included in a region, when creating a Region from a polygon.
The fill rule is only relevant for polygons which overlap themselves.
Enumeration values:

EVEN_ODD_RULE Areas which are overlapped an odd number of times are included in the region, while areas overlapped an even number of times are not.

WINDING_RULE Overlapping areas are always included.

enum OverlapType

Specifies the possible values returned by Gdk::Region::rect_in().

Enumeration values:

OVERLAP_RECTANGLE_IN The rectangle is inside the Region.

OVERLAP_RECTANGLE_OUT The rectangle is outside the Region.

OVERLAP_RECTANGLE_PART The rectangle is partly inside the Region.
