{{APIRef("WebGL")}}{{AvailableInWorkers}}

The WebGL2RenderingContext.getInternalformatParameter() method of the WebGL 2 API returns information about implementation-dependent support for internal formats.

Syntax

getInternalformatParameter(target, internalformat, pname)

Parameters

• target

  • : A {{domxref("WebGL_API/Types", "GLenum")}} specifying the target renderbuffer object. Possible values:
    • gl.RENDERBUFFER
      • : Buffer data storage for single images in a renderable internal format.

• internalformat

  • : A {{domxref("WebGL_API/Types", "GLenum")}} specifying the internal format about which to retrieve information (must be a color-renderable, depth-renderable or stencil-renderable format).

• pname

  • : A {{domxref("WebGL_API/Types", "GLenum")}} specifying the type of information to query. Possible values:
    • gl.SAMPLES
      • : Returns an {{jsxref("Int32Array")}} containing sample counts supported for internalformat in descending order.

Return value

Depends on the requested information (as specified with pname). It is an {{jsxref("Int32Array")}} if pname is gl.SAMPLES.

Examples

const samples = gl.getInternalformatParameter(
  gl.RENDERBUFFER,
  gl.RGBA8,
  gl.SAMPLES,
);
