Description

glGetTexParameter returns in params​ the value or values of the texture parameter specified as pname​. target​ defines the target texture. GL_TEXTURE_1D, GL_TEXTURE_2D, GL_TEXTURE_3D, GL_TEXTURE_1D_ARRAY, GL_TEXTURE_2D_ARRAY, GL_TEXTURE_RECTANGLE, GL_TEXTURE_CUBE_MAP, GL_TEXTURE_CUBE_MAP_ARRAY specify one-, two-, or three-dimensional, one-dimensional array, two-dimensional array, rectangle, cube-mapped or cube-mapped array texturing, respectively. pname​ accepts the same symbols as glTexParameter, with the same interpretations:

GL_DEPTH_STENCIL_TEXTURE_MODE
Returns the single-value depth stencil texture mode, a symbolic constant. The initial value is GL_DEPTH_COMPONENT.
GL_TEXTURE_MAG_FILTER
Returns the single-valued texture magnification filter, a symbolic constant. The initial value is GL_LINEAR.
GL_TEXTURE_MIN_FILTER
Returns the single-valued texture minification filter, a symbolic constant. The initial value is GL_NEAREST_MIPMAP_LINEAR.
GL_TEXTURE_MIN_LOD
GL_TEXTURE_MAX_LOD
Returns the single-valued texture maximum level-of-detail value. The initial value is 1000.
GL_TEXTURE_BASE_LEVEL
Returns the single-valued base texture mipmap level. The initial value is 0.
GL_TEXTURE_MAX_LEVEL
Returns the single-valued maximum texture mipmap array level. The initial value is 1000.
GL_TEXTURE_SWIZZLE_R
Returns the red component swizzle. The initial value is GL_RED.
GL_TEXTURE_SWIZZLE_G
Returns the green component swizzle. The initial value is GL_GREEN.
GL_TEXTURE_SWIZZLE_B
Returns the blue component swizzle. The initial value is GL_BLUE.
GL_TEXTURE_SWIZZLE_A
Returns the alpha component swizzle. The initial value is GL_ALPHA.
GL_TEXTURE_SWIZZLE_RGBA
Returns the component swizzle for all channels in a single query.
GL_TEXTURE_WRAP_S
Returns the single-valued wrapping function for texture coordinate s, a symbolic constant. The initial value is GL_REPEAT.
GL_TEXTURE_WRAP_T
Returns the single-valued wrapping function for texture coordinate t, a symbolic constant. The initial value is GL_REPEAT.
GL_TEXTURE_WRAP_R
Returns the single-valued wrapping function for texture coordinate r, a symbolic constant. The initial value is GL_REPEAT.
GL_TEXTURE_BORDER_COLOR
Returns four integer or floating-point numbers that comprise the RGBA color of the texture border. Floating-point values are returned in the range [0, 1]. Integer values are returned as a linear mapping of the internal floating-point representation such that 1.0 maps to the most positive representable integer and -1.0 maps to the most negative representable integer. The initial value is (0, 0, 0, 0).
GL_TEXTURE_COMPARE_MODE
Returns a single-valued texture comparison mode, a symbolic constant. The initial value is GL_NONE. See glTexParameter.
GL_TEXTURE_COMPARE_FUNC
Returns a single-valued texture comparison function, a symbolic constant. The initial value is GL_LEQUAL. See glTexParameter.
GL_TEXTURE_VIEW_MIN_LEVEL
Returns a single-valued base level of a texture view relative to its parent. The initial value is 0. See glTextureView.
GL_TEXTURE_VIEW_NUM_LEVELS
Returns a single-valued number of levels of detail of a texture view. See glTextureView.
GL_TEXTURE_VIEW_MIN_LAYER
Returns a single-valued first level of a texture array view relative to its parent. See glTextureView.
GL_TEXTURE_VIEW_NUM_LAYERS
Returns a single-valued number of layers in a texture array view. See glTextureView.
GL_TEXTURE_IMMUTABLE_LEVELS
Returns a single-valued number of immutable texture levels in a texture view. See glTextureView.

In addition to the parameters that may be set with glTexParameter, glGetTexParameter accepts the following read-only parameters:

GL_TEXTURE_IMMUTABLE_FORMAT
Returns non-zero if the texture has an immutable format. Textures become immutable if their storage is specified with glTexStorage1D, glTexStorage2D or glTexStorage3D. The initial value is GL_FALSE.

Notes

If an error is generated, no change is made to the contents of params​.

GL_DEPTH_STENCIL_TEXTURE_MODE, GL_TEXTURE_VIEW_MIN_LEVEL, GL_TEXTURE_VIEW_NUM_LEVELS, GL_TEXTURE_VIEW_MIN_LAYER, GL_TEXTURE_VIEW_NUM_LAYERS and GL_TEXTURE_IMMUTABLE_LEVELS are available only if the GL version is 4.3 or greater.

Errors

GL_INVALID_ENUM is generated if target​ or pname​ is not an accepted value.
