  19             <code class="function">glTexStorage2D</code> specifies the storage requirements for all levels
  20             of a two-dimensional texture or one-dimensional texture array simultaneously. Once a texture is specified with this
  21             command, the format and dimensions of all levels become immutable unless it is a proxy
  22             texture. The contents of the image may still be modified, however, its storage requirements
  23             may not change. Such a texture is referred to as an <span class="emphasis"><em>immutable-format</em></span>
  24             texture.
  25         </p><p>
  26             The behavior of <code class="function">glTexStorage2D</code> depends on the <em class="parameter"><code>target</code></em> parameter.
  27             When <em class="parameter"><code>target</code></em> is <code class="constant">GL_TEXTURE_2D</code>, <code class="constant">GL_PROXY_TEXTURE_2D</code>,
  28             <code class="constant">GL_TEXTURE_RECTANGLE</code>, <code class="constant">GL_PROXY_TEXTURE_RECTANGLE</code> or <code class="constant">GL_PROXY_TEXTURE_CUBE_MAP</code>,
  29             calling <code class="function">glTexStorage2D</code> is equivalent, assuming no errors are generated,
  30             to executing the following pseudo-code:
  31         </p><pre class="programlisting">    for (i = 0; i &lt; levels; i++)
  32     {
  33         glTexImage2D(target, i, internalformat, width, height, 0, format, type, NULL);
  34         width = max(1, (width / 2));
  35         height = max(1, (height / 2));
  36     }</pre><p>
  37             When <em class="parameter"><code>target</code></em> is <code class="constant">GL_TEXTURE_CUBE_MAP</code>, <code class="function">glTexStorage2D</code>
  38             is equivalent to:
  39         </p><pre class="programlisting">    for (i = 0; i &lt; levels; i++)
  40     {
  41         for (face in (+X, -X, +Y, -Y, +Z, -Z))
  42         {
  43             glTexImage2D(face, i, internalformat, width, height, 0, format, type, NULL);
  44         }
  45         width = max(1, (width / 2));
  46         height = max(1, (height / 2));
  47     }</pre><p>
  48             When <em class="parameter"><code>target</code></em> is <code class="constant">GL_TEXTURE_1D</code> or <code class="constant">GL_TEXTURE_1D_ARRAY</code>,
  49             <code class="function">glTexStorage2D</code> is equivalent to:
  50         </p><pre class="programlisting">    for (i = 0; i &lt; levels; i++)
  51     {
  52         glTexImage2D(target, i, internalformat, width, height, 0, format, type, NULL);
  53         width = max(1, (width / 2));
  54     }</pre><p>
  55             Since no texture data is actually provided, the values used in the pseudo-code
  56             for <em class="parameter"><code>format</code></em> and <em class="parameter"><code>type</code></em> are
  57             irrelevant and may be considered to be any values that are legal for the
  58             chosen <em class="parameter"><code>internalformat</code></em> enumerant. <em class="parameter"><code>internalformat</code></em>
  59             must be one of the sized internal formats given in Table 1 below, one of the sized depth-component
  60             formats <code class="constant">GL_DEPTH_COMPONENT32F</code>, <code class="constant">GL_DEPTH_COMPONENT24</code>, or
  61             <code class="constant">GL_DEPTH_COMPONENT16</code>, or one of the combined depth-stencil formats,
  62             <code class="constant">GL_DEPTH32F_STENCIL8</code>, or <code class="constant">GL_DEPTH24_STENCIL8</code>. Upon success,
  63             the value of <code class="constant">GL_TEXTURE_IMMUTABLE_FORMAT</code> becomes
  64             <code class="constant">GL_TRUE</code>. The value of <code class="constant">GL_TEXTURE_IMMUTABLE_FORMAT</code>
  65             may be discovered by calling <a href="glGetTexParameter.xml"><span class="citerefentry"><span class="refentrytitle">glGetTexParameter</span></span></a>
  66             with <em class="parameter"><code>pname</code></em> set to <code class="constant">GL_TEXTURE_IMMUTABLE_FORMAT</code>.
  67             No further changes to the dimensions or format of the texture object may be
  68             made. Using any command that might alter the dimensions or format of the
  69             texture object (such as <a href="glTexImage2D.xml"><span class="citerefentry"><span class="refentrytitle">glTexImage2D</span></span></a> or
  70             another call to <code class="function">glTexStorage2D</code>) will result in the
  71             generation of a <code class="constant">GL_INVALID_OPERATION</code> error, even if it
  72             would not, in fact, alter the dimensions or format of the object.
