	<h2>Description</h2>
	<p>
	<code class="function">eglCreatePlatformPixmapSurface</code> creates an
	off-screen <abbr class="acronym">EGL</abbr> pixmap surface and returns
	a handle to it.
	</p>
	<p>
	If <code class="function">eglCreatePlatformPixmapSurface</code> fails to
	create a pixmap surface, <code class="constant">EGL_NO_SURFACE</code> is
	returned.
	</p>
	<p>
	<em class="parameter"><code>native_pixmap</code></em> must belong to the same
	platform as <em class="parameter"><code>display</code></em>, and EGL considers
	the returned <span class="type">EGLSurface</span> as belonging to that same
	platform. The EGL extension that defines the platform to which
	<em class="parameter"><code>display</code></em> belongs also defines the
	requirements for the <em class="parameter"><code>native_pixmap</code></em>
	parameter.
	</p>
	<p>
	Surface attributes are specified as a list of
	attribute-value pairs, terminated with
	<code class="constant">EGL_NONE</code>. Accepted attributes

	Specifies the color space used by OpenGL and OpenGL ES
	when rendering to the surface. If its value is
	<code class="constant">EGL_GL_COLORSPACE_SRGB</code>, then a
	non-linear, perceptually uniform color space is assumed,
	with a corresponding
	<code class="constant">GL_FRAMEBUFFER_ATTACHMENT_COLOR_ENCODING</code>
	value of <code class="constant">GL_SRGB</code>. If its value is
	<code class="constant">EGL_GL_COLORSPACE_LINEAR</code>, then a
	linear color space is assumed, with a corresponding
	<code class="constant">GL_FRAMEBUFFER_ATTACHMENT_COLOR_ENCODING</code>
	value of <code class="constant">GL_LINEAR</code>. The default
	value of <code class="constant">EGL_GL_COLORSPACE</code> is
	<code class="constant">EGL_GL_COLORSPACE_SRGB</code>.

	<p>
	Note that the <code class="constant">EGL_GL_COLORSPACE</code>
	attribute is used only by OpenGL and OpenGL ES contexts
	supporting sRGB framebuffers. EGL itself does not
	distinguish multiple colorspace models. Refer to the

	non-linear, perceptually uniform color space is
	assumed, with a corresponding
	<span class="type">VGImageFormat</span> of form

	Any EGL rendering context that was created with respect to

	Attributes
	<code class="constant">EGL_VG_ALPHA_FORMAT</code> and

	The <code class="constant">EGL_VG_ALPHA_FORMAT</code> and

	by OpenVG and EGL itself. Refer to section 11.2 of the OpenVG
	1.0 specification for more information. The platform's use and
	interpretation of alpha values is outside the scope of EGL.
	However, the preferred behavior is for the window system to
	ignore the value of <code class="constant">EGL_VG_ALPHA_FORMAT</code>.
