The WebGL2RenderingContext.getSamplerParameter() method of the WebGL 2 API returns parameter information of a WebGLSampler object.

Syntax

any gl.getSamplerParameter(sampler, pname);

Parameters

sampler

A WebGLSampler object.

pname

A GLenum specifying which information to return. Possible values:

• gl.TEXTURE_COMPARE_FUNC: Returns a GLenum indicating the texture comparison function.
• gl.TEXTURE_COMPARE_MODE: Returns a GLenum indicating the texture comparison mode.
• gl.TEXTURE_MAG_FILTER: Returns a GLenum indicating the texture magnification filter.
• gl.TEXTURE_MAX_LOD: Returns a GLfloat indicating the maximum level-of-detail value.
• gl.TEXTURE_MIN_FILTER: Returns a GLenum indicating the texture minification filter
• gl.TEXTURE_MIN_LOD: Returns a GLfloat indicating the minimum level-of-detail value.
• gl.TEXTURE_WRAP_R: Returns a GLenum indicating the texture wrapping function for the texture coordinate r.
• gl.TEXTURE_WRAP_S: Returns a GLenum indicating the texture wrapping function for the texture coordinate s.
• gl.TEXTURE_WRAP_T: Returns a GLenum indicating the texture wrapping function for the texture coordinate t.

Return value

Depends on the pname parameter, either a GLenum or a GLfloat.
