This is an experimental technology
Because this technology's specification has not stabilized, check the compatibility table for usage in various browsers. Also note that the syntax and behavior of an experimental technology is subject to change in future versions of browsers as the specification changes.
The WebGL2RenderingContext.getInternalformatParameter() method of the WebGL 2 API returns information about implementation-dependent support for internal formats.
Syntax
any gl.getInternalformatParameter(target, internalformat, pname);
Parameters
target- A
Glenumspecifying the target renderbuffer object. Possible values:gl.RENDERBUFFER: Buffer data storage for single images in a renderable internal format.
internalformat- A
GLenumspecifying the internal format about which to retrieve information (must be a color-renderable, depth-renderable or stencil-renderable format). pname- A
GLenumspecifying the type of information to query. Possible values:gl.SAMPLES: Returns aInt32Arraycontaining sample counts supported forinternalformatin descending order.
Return value
Depends on the requested information (as specified with pname). It is an Int32Array if pname is gl.SAMPLES.
Examples
var samples = gl.getInternalformatParameter(gl.RENDERBUFFER,
gl.RGBA8, gl.SAMPLES);
