WebGL2RenderingContext.getInternalformatParameter() - Web APIs 编辑

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 Glenum specifying the target renderbuffer object. Possible values:

• gl.RENDERBUFFER: Buffer data storage for single images in a renderable internal format.

internalformat

A GLenum specifying the internal format about which to retrieve information (must be a color-renderable, depth-renderable or stencil-renderable format).

pname

A GLenum specifying the type of information to query. Possible values:

• gl.SAMPLES: Returns a Int32Array containing sample counts supported for internalformat in 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);
