eglSurfaceAttrib
- set an EGL surface attribute
EGLBoolean eglSurfaceAttrib(EGLDisplay display, EGLSurface surface, EGLint attribute, EGLint value)
display
Specifies the EGL display connection.
surface
Specifies the EGL surface.
attribute
Specifies the EGL surface attribute to set.
value
Specifies the attributes required value.
eglSurfaceAttrib
sets the value of attribute
for surface
to value
. attribute
can be one of the following:
EGL_MIPMAP_LEVEL
For mipmap textures, the EGL_MIPMAP_LEVEL
attribute indicates which level of the mipmap should be rendered. If the value of this attribute is outside the range of supported mipmap levels, the closest valid mipmap level is selected for rendering. The default value is 0
.
If the value of pbuffer attribute EGL_TEXTURE_FORMAT
is EGL_NO_TEXTURE
, if the value of attribute EGL_TEXTURE_TYPE
is EGL_NO_TEXTURE
, or if surface is not a pbuffer, then attribute EGL_MIPMAP_LEVEL
may be set, but has no effect.
EGL_FALSE
is returned on failure, EGL_TRUE
otherwise.
EGL_BAD_DISPLAY
is generated if display
is not an EGL display connection.
EGL_NOT_INITIALIZED
is generated if display
has not been initialized.
EGL_BAD_SURFACE
is generated if surface
is not an EGL surface.
EGL_BAD_ATTRIBUTE
is generated if attribute
is not a valid surface attribute.
