This extension is written against the wording of the EGL 1.4
|

|
Specification.
|
||
|
|
|
||
|
|
Overview
|
||
|
|
|
||
|
|
This extension allows creating EGL images from external metal texture objects.

|
Accepted in the <target> parameter of eglCreateImageKHR:
|
||
|
|
|
||
|
|
EGL_METAL_TEXTURE_ANGLE 0x34A7
|
||
|
|
|
||
|
|
Additions to Chapter 2 of the EGL 1.2 Specification (EGL Operation)
|
||
|
|
|
||
|
|
Add to section 2.5.1 "EGLImage Specification" (as defined by the
|
||
|
|
EGL_KHR_image_base specification), in the description of
|
||
|
|
eglCreateImageKHR:
|
||
|
|
|
||
|
|
"Values accepted for <target> are listed in Table aaa, below.
|
||
|
|
|
||
|
|
+----------------------------+-----------------------------------------+
|
||
|
|
| <target> | Notes |
|
||
|
|
+----------------------------+-----------------------------------------+
|
||
|
|
| EGL_METAL_TEXTURE_ANGLE | Used for Metal texture objects |
|
||
|
|
+----------------------------+-----------------------------------------+
|
||
|
|
Table aaa. Legal values for eglCreateImageKHR <target> parameter
|
||
|
|
|
||
|
|
...
|
||
|
|
|
||
|
|
If <target> is EGL_METAL_TEXTURE_ANGLE, <dpy> must be a valid display, <ctx>
|
||
|
|
must be EGL_NO_CONTEXT, <buffer> must be a pointer to a valid MTLTexture
|
||
|
|
object (cast into the type EGLClientBuffer), and attributes are ignored.
|
||
|
|
The width and height of the pbuffer are determined by the width and height
|
||
|
|
of <buffer>."
|
||
|
|
|
||
|
|
If the EGL_ANGLE_device_metal extension is present, the provided Metal texture
|
||
|
|
object must have been created by the same Metal device queried from the
|
||
|
|
display. If these requirements are not met, an EGL_BAD_PARAMETER error is
|
||
|
|
generated."
