<para>
<function>eglCreateImage</function> is used to create an
<type>EGLImage</type> object from an existing image resource
<parameter>buffer</parameter>. <parameter>display</parameter>
specifies the EGL display used for this operation.
<parameter>context</parameter> specifies the EGL client API
context used for this operation, or
<constant>EGL_NO_CONTEXT</constant> if a client API context is
not required. <parameter>target</parameter> specifies the type
of resource being used as the <type>EGLImage</type> source
(examples include two-dimensional textures in OpenGL ES contexts
and <type>VGImage</type> objects in OpenVG contexts).
<parameter>buffer</parameter> is the name (or handle) of a
resource to be used as the <type>EGLImage</type> source, cast
into the type <type>EGLClientBuffer</type>.
<parameter>attrib_list</parameter> is a list of attribute-value
pairs which is used to select sub-sections of
<parameter>buffer</parameter> for use as the
<type>EGLImage</type> source, such as mipmap levels for OpenGL
ES texture map resources, as well as behavioral options, such as
whether to preserve pixel data during creation. If
<parameter>attrib_list</parameter> is
non-<constant>NULL</constant>, the last attribute specified in
the list must be <constant>EGL_NONE</constant>.
</para>
<para>
The resource specified by <parameter>display</parameter>,
<parameter>context</parameter>, <parameter>target</parameter>,
<parameter>buffer</parameter>, and
<parameter>attrib_list</parameter> must not itself be an

(<function>eglBindTexImage</function>,
<function>eglCreatePbufferFromClientBuffer</function>).

<para>
Once an <type>EGLImage</type> is created from an
<type>EGLImage</type> source, the memory associated with the
<type>EGLImage</type> source will remain allocated (and all
<type>EGLImage</type> siblings in all client API contexts will
be useable) as long as either of the following conditions is
true:
</para>
<para>
<itemizedlist>
<listitem>
<para>
Any <type>EGLImage</type> siblings exist in any client
API context
</para>
</listitem>
<listitem>
<para>
The <type>EGLImage</type> object exists inside EGL
</para>
</listitem>
</itemizedlist>
</para>
<para>
The semantics for specifying, deleting and using
<type>EGLImage</type> siblings are client API-specific, and are
described in the appropriate API specifications.
</para>
<para>
If an application specifies an <type>EGLImage</type> sibling as
the destination for rendering and/or pixel download operations
(e.g., as an OpenGL or OpenGL ES framebuffer object,
<function>glTexSubImage2D</function>, etc.), the modified image
results will be observed by all <type>EGLImage</type> siblings
in all client API contexts. If multiple client API contexts
access <type>EGLImage</type> sibling resources simultaneously,
with one or more context modifying the image data, rendering
results in all contexts accessing <type>EGLImage</type> siblings
are undefined.
</para>
<para>
Respecification and/or deletion of any <type>EGLImage</type>
sibling (i.e., both <type>EGLImage</type> source and
<type>EGLImage</type> target resources) inside a client API
context (by issuing a subsequent call to commands such as
<function>glTexImage*</function> or
<function>glDeleteTextures</function>, with the
<type>EGLImage</type> sibling resource as the target of the
operation) affects only that client API context and other
contexts within its share group. For an OpenGL or OpenGL ES
context, respecification always results in
<firstterm>orphaning</firstterm> of the <type>EGLImage</type>,
and may also include allocation of additional memory for the
respecified resource and/or copying of the <type>EGLImage</type>
pixel data.
</para>
<para>
Note: Behavior of other types of client APIs generally follows
the OpenGL and OpenGL ES behavior described here, although this
is not mandated yet.
</para>
<para>
Operations inside EGL or any client API context which may affect
the lifetime of an <type>EGLImage</type> (or the memory
allocated for the <type>EGLImage</type>), such as respecifying
and/or deleting an <type>EGLImage</type> sibling inside a client
API context, must be atomic.
</para>
<para>
Applications may create client API resources from an
<type>EGLImage</type> using client API extensions outside the
scope of this document (such as
<constant>GL_OES_EGL_image</constant>, which creates OpenGL ES
texture and renderbuffer objects). If the <type>EGLImage</type>
used to create the client resource was created with the
<constant>EGL_IMAGE_PRESERVED</constant> attribute set to
<constant>EGL_TRUE</constant>, then the pixel data values
associated with the image will be preserved after creating the
client resource; otherwise, the pixel data values will be
undefined. If the <type>EGLImage</type> was created with the
<constant>EGL_IMAGE_PRESERVED</constant> attribute set to
<constant>EGL_TRUE</constant>, and EGL is unable to create the
client resource without modifying the pixel values, then
creation will fail and the pixel data values will be preserved.
