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.
