cairo_surface_t* cairo_win32_surface_create (HDC hdc);
Creates a cairo surface that targets the given DC. The DC will be queried for its initial clip extents, and this will be used as the size of the cairo surface. Also, if the DC is a raster DC, it will be queried for its pixel format and the cairo surface format will be set appropriately.

the DC to create a surface for |
Returns : |
the newly created surface |
cairo_surface_t* cairo_win32_surface_create_with_dib (cairo_format_t format, int width, int height);
Creates a device-independent-bitmap surface not associated with any particular existing surface or device context. The created bitmap will be unititialized.
|
format of pixels in the surface to create |
|
width of the surface, in pixels |
|
height of the surface, in pixels |
Returns : |
the newly created surface |
Since 1.2
HDC cairo_win32_surface_get_dc (cairo_surface_t *surface);
Returns the HDC associated with this surface, or NULL if none. Also returns NULL if the surface is not a win32 surface.
|
a cairo_surface_t |
Returns : |
HDC or NULL if no HDC available. |
