NAME

6       glXCreateGLXPixmap - create an off-screen GLX rendering area
7

C SPECIFICATION

9       GLXPixmap glXCreateGLXPixmap(Display * dpy, XVisualInfo * vis,
10                                    Pixmap pixmap);
11

PARAMETERS

13       dpy
14           Specifies the connection to the X server.
15
16       vis
17           Specifies the visual that defines the structure of the rendering
18           area. It is a pointer to an XVisualInfo structure, not a visual ID
19           or a pointer to a Visual.
20
21       pixmap
22           Specifies the X pixmap that will be used as the front left color
23           buffer of the off-screen rendering area.
24

DESCRIPTION

26       glXCreateGLXPixmap creates an off-screen rendering area and returns its
27       XID. Any GLX rendering context that was created with respect to vis can
28       be used to render into this off-screen area. Use glXMakeCurrent() to
29       associate the rendering area with a GLX rendering context.
30
31       The X pixmap identified by pixmap is used as the front left buffer of
32       the resulting off-screen rendering area. All other buffers specified by
33       vis, including color buffers other than the front left buffer, are
34       created without externally visible names. GLX pixmaps with
35       double-buffering are supported. However, glXSwapBuffers() is ignored by
36       these pixmaps.
37
38       Some implementations may not support GLX pixmaps with direct rendering
39       contexts.
40

NOTES

42       XVisualInfo is defined in Xutil.h.  It is a structure that includes
43       visual, visualID, screen, and depth elements.
44

ERRORS

46       BadMatch is generated if the depth of pixmap does not match the depth
47       value reported by core X11 for vis, or if pixmap was not created with
48       respect to the same screen as vis.
49
50       BadValue is generated if vis is not a valid XVisualInfo pointer (for
51       example, if a particular GLX implementation does not support this
52       visual).
53
54       BadPixmap is generated if pixmap is not a valid pixmap.
55
56       BadAlloc is generated if the server cannot allocate the GLX pixmap.
