EGLSurface eglCreatePbufferSurface (EGLDisplay display ,
EGLConfig config ,
const EGLint * attribList )

display specifies the EGL display connection
config specifies the configuration
attribList specifies the list of pixel buffer attributes; may be NULL

As with window creation, this function takes our connection to the native
display manager and the EGLConfig that we selected. This call also takes a
list of attributes, as described in Table 3-4.

Table 3-4

EGL Pixel Buffer Attributes

Token Description Default Value

EGL_WIDTH

Specifies the desired width (in
pixels) of the pbuffer.

0

EGL_HEIGHT

Specifies the desired height
(in pixels) of the pbuffer.

0

EGL_LARGEST_PBUFFER Select the largest available
pbuffer if one of the
requested size is not available.
Valid values are EGL_TRUE
and EGL_FALSE .

EGL_FALSE

EGL_TEXTURE_FORMAT EGL_NO_TEXTURE

Specifies the type of texture
format (see Chapter 9,
“Texturing”) if the pbuffer is
bound to a texture map. Valid
values are EGL_TEXTURE_RGB ,
EGL_TEXTURE_RGBA , and
EGL_NO_TEXTURE (which
indicates that the pbuffer
will not be used directly as a
texture).

EGL_TEXTURE_TARGET EGL_NO_TEXTURE Specifies the associated texture

target that the pbuffer should
be attached to if used as a
texture map (see Chapter 9,
“Texturing”). Valid values are
EGL_TEXTURE_2D and EGL_
NO_TEXTURE .
