NAMEglTexStorage2D, glTextureStorage2D − simultaneously specify storage for all levels of a two−dimensional or one−dimensional array texture
C SPECIFICATIONvoid glTexStorage2D(GLenum target, GLsizei levels, GLenum internalformat, GLsizei width, GLsizei height); void glTextureStorage2D(GLuint texture, GLsizei levels, GLenum internalformat, GLsizei width, GLsizei height);
PARAMETERStarget Specifies the target to which the texture object is bound for glTexStorage2D​. Must be one of GL_TEXTURE_2D, GL_TEXTURE_1D_ARRAY, GL_TEXTURE_RECTANGLE, GL_TEXTURE_CUBE_MAP, GL_PROXY_TEXTURE_2D, GL_PROXY_TEXTURE_1D_ARRAY, GL_PROXY_TEXTURE_RECTANGLE, or GL_PROXY_TEXTURE_CUBE_MAP​. texture Specifies the texture object name for glTextureStorage2D​. The effective target of texture must be one of the valid non−proxy target values above​. levels Specify the number of texture levels​. internalformat Specifies the sized internal format to be used to store texture image data​. width Specifies the width of the texture, in texels​. height Specifies the height of the texture, in texels​.
DESCRIPTIONglTexStorage2D and glTextureStorage2D specify the storage requirements for all levels of a two−dimensional texture or one−dimensional texture array simultaneously​. Once a texture is specified with this command, the format and dimensions of all levels become immutable unless it is a proxy texture​. The contents of the image may still be modified, however, its storage requirements may not change​. Such a texture is referred to as an immutable−format texture​. The behavior of glTexStorage2D depends on the target parameter​. When target is GL_TEXTURE_2D, GL_PROXY_TEXTURE_2D, GL_TEXTURE_RECTANGLE, GL_PROXY_TEXTURE_RECTANGLE or GL_PROXY_TEXTURE_CUBE_MAP, calling glTexStorage2D is equivalent, assuming no errors are generated, to executing the following pseudo−code: for (i = 0; i < levels; i++) { glTexImage2D(target, i, internalformat, width, height, 0, format, type, NULL); width = max(1, (width / 2)); height = max(1, (height / 2)); }When target is GL_TEXTURE_CUBE_MAP, glTexStorage2D is equivalent to: for (i = 0; i < levels; i++) { for (face in (+X, −X, +Y, −Y, +Z, −Z)) { glTexImage2D(face, i, internalformat, width, height, 0, format, type, NULL); } width = max(1, (width / 2)); height = max(1, (height / 2)); }When target is GL_TEXTURE_1D_ARRAY or GL_PROXY_TEXTURE_1D_ARRAY, glTexStorage2D is equivalent to: for (i = 0; i < levels; i++) { glTexImage2D(target, i, internalformat, width, height, 0, format, type, NULL); width = max(1, (width / 2)); }Calling glTextureStorage2D is equivalent to the above pseudo−code, where target is the effective target of texture and it is as if texture were bound to target for the purposes of glTexImage2D​. Since no texture data is actually provided, the values used in the pseudo−code for format and type are irrelevant and may be considered to be any values that are legal for the chosen internalformat enumerant​. internalformat must be one of the sized internal formats given in Table 1 below, one of the sized depth−component formats GL_DEPTH_COMPONENT32F, GL_DEPTH_COMPONENT24, or GL_DEPTH_COMPONENT16, one of the combined depth−stencil formats, GL_DEPTH32F_STENCIL8, or GL_DEPTH24_STENCIL8, or the stencil−only format, GL_STENCIL_INDEX8​. Upon success, the value of GL_TEXTURE_IMMUTABLE_FORMAT becomes GL_TRUE​. The value of GL_TEXTURE_IMMUTABLE_FORMAT may be discovered by calling glGetTexParameter() with pname set to GL_TEXTURE_IMMUTABLE_FORMAT​. No further changes to the dimensions or format of the texture object may be made​. Using any command that might alter the dimensions or format of the texture object (such as glTexImage2D() or another call to glTexStorage2D) will result in the generation of a GL_INVALID_OPERATION error, even if it would not, in fact, alter the dimensions or format of the object​. .it 1 an-trap

NOTESGL_STENCIL_INDEX8 is accepted for internalformat only if the GL version is 4​.4 or higher​.
ERRORSGL_INVALID_OPERATION is generated by glTexStorage2D if zero is bound to target​. GL_INVALID_OPERATION is generated by glTextureStorage2D if texture is not the name of an existing texture object​. GL_INVALID_ENUM is generated if internalformat is not a valid sized internal format​. GL_INVALID_ENUM is generated if target or the effective target of texture is not one of the accepted targets described above​. GL_INVALID_VALUE is generated if width, height or levels are less than 1​. GL_INVALID_OPERATION is generated if target is GL_TEXTURE_1D_ARRAY or GL_PROXY_TEXTURE_1D_ARRAY and levels is greater than log 2 width + 1​. GL_INVALID_OPERATION is generated if target is not GL_TEXTURE_1D_ARRAY or GL_PROXY_TEXTURE_1D_ARRAY and levels is greater than log 2 max width ,  ​ height + 1​.
