GLXCREATEPBUFFER(3G) OpenGL Manual GLXCREATEPBUFFER(3G)
NAME
glXCreatePbuffer - create an off-screen rendering area
C SPECIFICATION
GLXPbuffer glXCreatePbuffer(Display * dpy, GLXFBConfig config,
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.
attrib_list
Specifies a list of attribute value pairs, which must be terminated
with None or NULL. Accepted attributes are GLX_PBUFFER_WIDTH,
GLX_PBUFFER_HEIGHT, GLX_PRESERVED_CONTENTS, and
GLX_LARGEST_PBUFFER.
DESCRIPTION
glXCreatePbuffer 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 glXMakeContextCurrent() to
associate the rendering area with a GLX rendering context.
The accepted attributes for a GLXPbuffer are:
GLX_PBUFFER_WIDTH
Specify the pixel width of the requested GLXPbuffer. The default
value is 0.
GLX_PBUFFER_HEIGHT
Specify the pixel height of the requested GLXPbuffer. The default
value is 0.
GLX_LARGEST_PBUFFER
Specify to obtain the largest available pixel buffer, if the
requested allocation would have failed. The width and height of the
allocated pixel buffer will never exceed the specified
GLX_PBUFFER_WIDTH or GLX_PBUFFER_HEIGHT, respectively. Use
glXQueryDrawable() to retrieve the dimensions of the allocated
pixel buffer. The default value is False.
GLX_PRESERVED_CONTENTS
Specify if the contents of the pixel buffer should be preserved
when a resource conflict occurs. If set to False, the contents of
the pixel buffer may be lost at any time. If set to True, or not
specified in attrib_list, then the contents of the pixel buffer
will be preserved (most likely by copying the contents into main
system memory from the frame buffer). In either case, the client
can register (using glXSelectEvent(), to receive pixel buffer
clobber events that are generated when the pbuffer contents have
been preserved or damaged.
GLXPbuffers contain the color and ancillary buffers specified by
config. It is possible to create a pixel buffer with back buffers and
to swap those buffers using glXSwapBuffers().
NOTES
glXCreatePbuffer 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.
GLXPbuffers are allocated from frame buffer resources; applications
should consider deallocating them when they are not in use.
ERRORS
BadAlloc is generated if there are insufficient resources to allocate
the requested GLXPbuffer.
GLXBadFBConfig is generated if config is not a valid GLXFBConfig.
BadMatch is generated if config does not support rendering to pixel
buffers (e.g., GLX_DRAWABLE_TYPE does not contain GLX_PBUFFER_BIT).
