It does - * not directly provide for applying additional OpenGL effects to - * cairo surfaces. - * - * Cairo-gl allows interoperability with other GL rendering through GL - * context sharing. Cairo-gl surfaces are created in reference to a - * #cairo_device_t, which represents a GL context created by the user. - * When that GL context is created with its sharePtr set to another - * context (or vice versa), its objects (textures backing cairo-gl - * surfaces) can be accessed in the other OpenGL context. This allows - * cairo-gl to maintain its drawing state in one context while the - * user's 3D rendering occurs in the user's other context. - * - * However, as only one context can be current to a thread at a time, - * cairo-gl may make its context current to the thread on any cairo - * call which interacts with a cairo-gl surface or the cairo-gl - * device. As a result, the user must make their own context current - * between any cairo calls and their own OpenGL rendering. - **/ - -#ifndef CAIRO_GL_H -#define CAIRO_GL_H - -#include "cairo.h" - -#if CAIRO_HAS_GL_SURFACE || CAIRO_HAS_GLESV2_SURFACE || CAIRO_HAS_GLESV3_SURFACE - -CAIRO_BEGIN_DECLS - -cairo_public cairo_surface_t * -cairo_gl_surface_create (cairo_device_t *device, - cairo_content_t content, - int width, int height); - -cairo_public cairo_surface_t * -cairo_gl_surface_create_for_texture (cairo_device_t *abstract_device, - cairo_content_t content, - unsigned int tex, - int width, int height); -cairo_public void -cairo_gl_surface_set_size (cairo_surface_t *surface, int width, int height); - -cairo_public int -cairo_gl_surface_get_width (cairo_surface_t *abstract_surface); - -cairo_public int -cairo_gl_surface_get_height (cairo_surface_t *abstract_surface); - -cairo_public void -cairo_gl_surface_swapbuffers (cairo_surface_t *surface); - -cairo_public void -cairo_gl_device_set_thread_aware (cairo_device_t *device, - cairo_bool_t thread_aware); - -#if CAIRO_HAS_GLX_FUNCTIONS -#include <GL/glx.h> - -cairo_public cairo_device_t * -cairo_glx_device_create (Display *dpy, GLXContext gl_ctx); - -cairo_public Display * -cairo_glx_device_get_display (cairo_device_t *device); - -cairo_public GLXContext -cairo_glx_device_get_context (cairo_device_t *device); - -cairo_public cairo_surface_t * -cairo_gl_surface_create_for_window (cairo_device_t *device, - Window win, - int width, int height); -#endif - -#if CAIRO_HAS_WGL_FUNCTIONS -#include <windows.h> - -cairo_public cairo_device_t * -cairo_wgl_device_create (HGLRC rc); - -cairo_public HGLRC -cairo_wgl_device_get_context (cairo_device_t *device); - -cairo_public cairo_surface_t * -cairo_gl_surface_create_for_dc (cairo_device_t *device, - HDC dc, - int width, - int height); -#endif - -#if CAIRO_HAS_EGL_FUNCTIONS -#include <EGL/egl.h> - -cairo_public cairo_device_t * -cairo_egl_device_create (EGLDisplay dpy, EGLContext egl); - -cairo_public cairo_surface_t * -cairo_gl_surface_create_for_egl (cairo_device_t *device, - EGLSurface egl, - int width, - int height); - -cairo_public EGLDisplay -cairo_egl_device_get_display (cairo_device_t *device); - -cairo_public EGLSurface -cairo_egl_device_get_context (cairo_device_t *device); - -#endif - -CAIRO_END_DECLS - -#else /* CAIRO_HAS_GL_SURFACE */ -# error Cairo was not compiled with support for the GL backend -#endif /* CAIRO_HAS_GL_SURFACE */ - -#endif /* CAIRO_GL_H */ |
