Class CairoGraphics2D

public CairoGraphics2D()

Constructor does nothing.

public void addRenderingHints(Map hints)

Adds/updates the rendering hint.

Overrides:

addRenderingHints in interface Graphics2D

Parameters:

hints - the hints to add or update.

public void clearRect(int x,
                      int y,
                      int width,
                      int height)

Note that the rest of the drawing methods go via fill() or draw() for the drawing, although subclasses may with to overload these methods where context-specific optimizations are possible (e.g. bitmaps and fillRect(int, int, int, int)

Overrides:

clearRect in interface Graphics

public void clip(Shape s)

Sets the clip region to the intersection of the current clipping region and s.

Overrides:

clip in interface Graphics2D

Parameters:

s - the shape to intersect with the current clipping region.

public void copy(CairoGraphics2D g,
                 long cairo_t_pointer)

Same as above, but copies the state of another CairoGraphics2D.

public void copyArea(int ox,
                     int oy,
                     int owidth,

Overrides:
