cairo_quartz_surface_create ()

cairo_surface_t *
cairo_quartz_surface_create (cairo_format_t format,
                             unsigned int width,
                             unsigned int height);

Creates a Quartz surface backed by a CGBitmap. The surface is created using the Device RGB (or Device Gray, for A8) color space. All Cairo operations, including those that require software rendering, will succeed on this surface.

cairo_quartz_surface_create_for_cg_context ()

cairo_surface_t *
cairo_quartz_surface_create_for_cg_context
                               (CGContextRef cgContext,
                                unsigned int width,
                                unsigned int height);

Creates a Quartz surface that wraps the given CGContext. The CGContext is assumed to be in the standard Cairo coordinate space (that is, with the origin at the upper left and the Y axis increasing downward). If the CGContext is in the Quartz coordinate space (with the origin at the bottom left), then it should be flipped before this function is called. The flip can be accomplished using a translate and a scale; for example:

CGContextTranslateCTM (cgContext, 0.0, height);
CGContextScaleCTM (cgContext, 1.0, -1.0);

All Cairo operations are implemented in terms of Quartz operations, as long as Quartz-compatible elements are used (such as Quartz fonts).

cairo_quartz_surface_get_cg_context ()

CGContextRef
cairo_quartz_surface_get_cg_context (cairo_surface_t *surface);

Returns the CGContextRef that the given Quartz surface is backed by.

A call to cairo_surface_flush() is required before using the CGContextRef to ensure that all pending drawing operations are finished and to restore any temporary modification cairo has made to its state. A call to cairo_surface_mark_dirty() is required after the state or the content of the CGContextRef has been modified.

Since: 1.6

CAIRO_HAS_QUARTZ_SURFACE

#define CAIRO_HAS_QUARTZ_SURFACE 1

Defined if the Quartz surface backend is available. This macro can be used to conditionally compile backend-specific code.
