QuartzSurface (cairo_surface_t*cobject, bool has_reference=false) | |
Create a C++ wrapper for the C instance. | |
virtual | ~QuartzSurface () |
CGContextRef | get_cg_context () const |
Returns the CGContextRef associated with this surface, or NULL if none. | |

static RefPtr< QuartzSurface > | create (CGContextRef cg_context, int width, int height) |
Creates a cairo surface that targets the given CGContext. | |
static RefPtr< QuartzSurface > | create (Format format, int width, int height) |
Creates a device-independent-bitmap surface not associated with any particular existing surface or device context. |
A QuartzSurface provides a way to render within Apple Mac OS X.
If you want to draw to the screen within a Mac OS X application, you should use this Surface type.
Cairo::QuartzSurface::QuartzSurface | ( | cairo_surface_t * | cobject, | |
bool | has_reference = false | |||
) | [explicit] |
Create a C++ wrapper for the C instance.
This C++ instance should then be given to a RefPtr.
cobject | The C instance. | |
has_reference | whether we already have a reference. Otherwise, the constructor will take an extra reference. |

static RefPtr<QuartzSurface> Cairo::QuartzSurface::create | ( | CGContextRef | cg_context, | |
int | width, | |||
int | height | |||
) | [static] |
Creates a cairo surface that targets the given CGContext.

static RefPtr<QuartzSurface> Cairo::QuartzSurface::create | ( | Format | format, | |
int | width, | |||
int | height | |||
) | [static] |
Creates a device-independent-bitmap surface not associated with any particular existing surface or device context.
The created bitmap will be unititialized.
format | format of pixels in the surface to create | |
width | width of the surface, in pixels | |
height | height of the surface, in pixels |
CGContextRef Cairo::QuartzSurface::get_cg_context | ( | ) | const |
Returns the CGContextRef associated with this surface, or NULL if none.
Also returns NULL if the surface is not a Quartz surface.
