| |
| Dependencies |

| 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." |
