Gl.GetRenderbufferParameterivEXT (gb.opengl)
Static Function GetRenderbufferParameterivEXT ( Target As Integer, Pname As Integer ) As Integer[]
Parameters
- target
-
Specifies the target of the query operation. target must be Gl.RENDERBUFFER.
- pname
-
Specifies the parameter whose value to retrieve from the renderbuffer bound to target.
- params
-
Specifies the address of an array to receive the value of the queried parameter.
Description
Gl.GetRenderbufferParameteriv retrieves information about a bound renderbuffer object.
target
specifies the target of the query operation and must be Gl.RENDERBUFFER.
pname specifies
the parameter whose value to query and must be one of Gl.RENDERBUFFER_WIDTH, Gl.RENDERBUFFER_HEIGHT,
Gl.RENDERBUFFER_INTERNAL_FORMAT, Gl.RENDERBUFFER_RED_SIZE, Gl.RENDERBUFFER_GREEN_SIZE,
Gl.RENDERBUFFER_BLUE_SIZE, Gl.RENDERBUFFER_ALPHA_SIZE, Gl.RENDERBUFFER_DEPTH_SIZE,
Gl.RENDERBUFFER_DEPTH_SIZE, Gl.RENDERBUFFER_STENCIL_SIZE, or Gl.RENDERBUFFER_SAMPLES.
Upon a successful return from
Gl.GetRenderbufferParameteriv, if
pname is Gl.RENDERBUFFER_WIDTH,
Gl.RENDERBUFFER_HEIGHT, Gl.RENDERBUFFER_INTERNAL_FORMAT, or Gl.RENDERBUFFER_SAMPLES,
then
params will contain the width in pixels, the height in pixels, the internal format, or the number of samples, respectively,
of the image of the renderbuffer currently bound to
target.
If
pname is Gl.RENDERBUFFER_RED_SIZE, Gl.RENDERBUFFER_GREEN_SIZE,
Gl.RENDERBUFFER_BLUE_SIZE, Gl.RENDERBUFFER_ALPHA_SIZE, Gl.RENDERBUFFER_DEPTH_SIZE,
or Gl.RENDERBUFFER_STENCIL_SIZE, then
params will contain the actual resolutions (not the resolutions
specified when the image array was defined) for the red, green, blue, alpha depth, or stencil components, respectively, of the image of the
renderbuffer currently bound to
target.
Errors
Gl.INVALID_ENUM is generated if
pname is not one of the accepted tokens.
