Function glGetTexParameterfv

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, and GL_TEXTURE_CUBE_MAP specify one-, two-, or three-dimensional, one-dimensional array, two-dimensional array, rectangle or cube-mapped texturing, respectively. pname accepts the same symbols as glTexParameter, with the same interpretations:

• 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 Returns the single-valued texture minimum level-of-detail value. The initial value is −1000.

• 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.
