The WebGLRenderingContext.getTexParameter()
method of the WebGL API returns information about the given texture.
The WebGLRenderingContext.getTexParameter()
method of the WebGL API returns information about the given texture.
js
getTexParameter(target, pname)
target
A GLenum
specifying the binding point (target). Possible values:
gl.TEXTURE_2D
: A two-dimensional texture.gl.TEXTURE_CUBE_MAP
: A cube-mapped texture.When using a WebGL 2 context, the following values are available additionally:
gl.TEXTURE_3D
: A three-dimensional texture.gl.TEXTURE_2D_ARRAY
: A two-dimensional array texture.pname
A GLenum
specifying the information to query. Possible values:
