GLXCREATEPIXMAP(3G)						   OpenGL Manual					       GLXCREATEPIXMAP(3G)

NAME

       glXCreatePixmap - create an off-screen rendering area

C SPECIFICATION

       GLXPixmap glXCreatePixmap(Display * dpy, GLXFBConfig config, Pixmap pixmap, const int * attrib_list);

PARAMETERS

       dpy
	   Specifies the connection to the X server.

       config
	   Specifies a GLXFBConfig structure with the desired attributes for the window.

       pixmap
	   Specifies the X pixmap to be used as the rendering area.

       attrib_list
	   Currently unused. This must be set to NULL or be an empty list (i.e., one in which the first element is None).

DESCRIPTION

       glXCreatePixmap creates an off-screen rendering area and returns its XID. Any GLX rendering context that was created with respect to config
       can be used to render into this window. Use glXMakeCurrent() to associate the rendering area with a GLX rendering context.

NOTES

       glXCreatePixmap is available only if the GLX version is 1.3 or greater.

       If the GLX version is 1.1 or 1.0, the GL version must be 1.0. If the GLX version is 1.2, then the GL version must be 1.1. If the GLX
       version is 1.3, then the GL version must be 1.2.

ERRORS

       BadMatch is generated if pixmap was not created with a visual that corresponds to config.

       BadMatch is generated if config does not support rendering to windows (e.g., GLX_DRAWABLE_TYPE does not contain GLX_WINDOW_BIT).

       BadWindow is generated if pixmap is not a valid window XID.  BadAlloc is generated if there is already a GLXFBConfig associated with
       pixmap.

       BadAlloc is generated if the X server cannot allocate a new GLX window.

       GLXBadFBConfig is generated if config is not a valid GLXFBConfig.

NAME

       glXCreateGLXPixmap - create an off-screen GLX rendering area

C SPECIFICATION

       GLXPixmap glXCreateGLXPixmap( Display *dpy,
				     XVisualInfo *vis,
				     Pixmap pixmap )

       delim $$

PARAMETERS

       dpy     Specifies the connection to the X server.

       vis     Specifies  the  visual that defines the structure of the rendering area.  It is a pointer to an XVisualInfo structure, not a visual
	       ID or a pointer to a Visual.

       pixmap  Specifies the X pixmap that will be used as the front left color buffer of the off-screen rendering area.

DESCRIPTION

       glXCreateGLXPixmap creates an off-screen rendering area and returns its XID.  Any GLX rendering context that was created  with  respect	to
       vis can be used to render into this off-screen area.  Use glXMakeCurrent to associate the rendering area with a GLX rendering context.

       The X pixmap identified by pixmap is used as the front left buffer of the resulting off-screen rendering area.  All other buffers specified
       by vis, including color buffers other than the front left buffer, are created without externally visible names.	GLX pixmaps  with  double-
       buffering are supported.  However, glXSwapBuffers is ignored by these pixmaps.

       Some implementations may not support GLX pixmaps with direct rendering contexts.

NOTES

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

ERRORS

       BadMatch is generated if the depth of pixmap does not match the depth value reported by core X11 for vis, or if pixmap was not created with
       respect to the same screen as vis.

       BadValue is generated if vis is not a valid XVisualInfo pointer (for example, if a particular GLX implementation does not support this vis-
       ual).

       BadPixmap is generated if pixmap is not a valid pixmap.

       BadAlloc is generated if the server cannot allocate the GLX pixmap.
