Web/API/WebGLRenderingContext/getTexParameter

The WebGLRenderingContext.getTexParameter() method of the WebGL API returns information about the given texture.

Syntax

any gl.getTexParameter(target, pname);

Parameters

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:

pname	Return type	Description	Possible return values
Available in a WebGL 1 context
`gl.TEXTURE_MAG_FILTER`	`GLenum`	Texture magnification filter	`gl.LINEAR` (default value), `gl.NEAREST`.
`gl.TEXTURE_MIN_FILTER`	`GLenum`	Texture minification filter	`gl.LINEAR`, `gl.NEAREST`, `gl.NEAREST_MIPMAP_NEAREST`, `gl.LINEAR_MIPMAP_NEAREST`, `gl.NEAREST`_MIPMAP_LINEAR (default value), `gl.LINEAR_MIPMAP_LINEAR`.
`gl.TEXTURE_WRAP_S`	`GLenum`	Wrapping function for texture coordinate `s`	`gl.REPEAT` (default value), `gl.CLAMP_TO_EDGE`, `gl.MIRRORED_REPEAT`.
`gl.TEXTURE_WRAP_T`	`GLenum`	Wrapping function for texture coordinate `t`	`gl.REPEAT` (default value), `gl.CLAMP_TO_EDGE`, `gl.MIRRORED_REPEAT`.
Additionally available when using the `EXT_texture_filter_anisotropic` extension
`ext.TEXTURE_MAX_ANISOTROPY_EXT`	`GLfloat`	Maximum anisotropy for a texture	Any float values.
Additionally available when using a WebGL 2 context
`gl.TEXTURE_BASE_LEVEL`	`GLint`	Texture mipmap level	Any int values.
`gl.TEXTURE_COMPARE_FUNC`	`GLenum`	Comparison function	`gl.LEQUAL` (default value), `gl.GEQUAL`, `gl.LESS`, `gl.GREATER`, `gl.EQUAL`, `gl.NOTEQUAL`, `gl.ALWAYS`, `gl.NEVER`.
`gl.TEXTURE_COMPARE_MODE`	`GLenum`	Texture comparison mode	`gl.NONE` (default value), `gl.COMPARE_REF_TO_TEXTURE`.
`gl.TEXTURE_IMMUTABLE_FORMAT`	`GLboolean`	Immutability of the texture format and size	true or false.
`gl.TEXTURE_IMMUTABLE_LEVELS`	`GLuint`	?	Any uint values.
`gl.TEXTURE_MAX_LEVEL`	`GLint`	Maximum texture mipmap array level	Any int values.
`gl.TEXTURE_MAX_LOD`	`GLfloat`	Texture maximum level-of-detail value	Any float values.
`gl.TEXTURE_MIN_LOD`	`GLfloat`	Texture minimum level-of-detail value	Any float values.
`gl.TEXTURE_WRAP_R`	`GLenum`	Wrapping function for texture coordinate `r`	`gl.REPEAT` (default value), `gl.CLAMP_TO_EDGE`, `gl.MIRRORED_REPEAT`.

Return value

Returns the requested texture information (as specified with pname). If an error occurs, null is returned.

Examples

gl.getTexParameter(gl.TEXTURE_2D, gl.TEXTURE_MAG_FILTER);
