Name ANGLE_d3d_share_handle_client_buffer Name Strings EGL_ANGLE_d3d_share_handle_client_buffer Contributors John Bauman Alastair Patrick Daniel Koch Contacts John Bauman, Google Inc. (jbauman 'at' chromium.org) Status Complete Implemented (ANGLE r650) Version Version 3, May 12, 2011 Number EGL Extension #?? Dependencies Requires the EGL_ANGLE_surface_d3d_texture_2d_share_handle extension. This extension is written against the wording of the EGL 1.4 Specification. Overview This extension allows creating EGL surfaces from handles to textures shared from the Direct3D API or from EGL_ANGLE_surface_texture_2d_share_handle. New Types None New Procedures and Functions None New Tokens Accepted in the parameter of eglCreatePbufferFromClientBuffer: EGL_D3D_TEXTURE_2D_SHARE_HANDLE_ANGLE 0x3200 Additions to Chapter 3 of the EGL 1.4 Specification (EGL Functions and Errors) Replace the last sentence of paragraph 1 of Section 3.5.3 with the following text. "Currently, the only client API resources which may be bound in this fashion are OpenVG VGImage objects and Direct3D share handles." Replace the last sentence of paragraph 2 ("To bind a client API...") of Section 3.5.3 with the following text. "When is EGL_OPENVG_IMAGE, the width and height of the pbuffer are determined by the width and height of . When is EGL_D3D_TEXTURE_2D_SHARE_HANDLE_ANGLE, the width and height are specified using EGL_WIDTH and EGL_HEIGHT, or else they default to zero. The width and height must match the dimensions of the texture which the share handle was created from or else an EGL_BAD_ALLOC error is generated." Replace the third paragraph of Section 3.5.3 with the following text. " specifies the type of buffer to be bound. The only allowed values of are EGL_OPENVG_IMAGE and EGL_D3D_TEXTURE_2D_SHARE_HANDLE_ANGLE". Append the following text to the fourth paragraph of Section 3.5.3. "When is EGL_D3D_TEXTURE_2D_SHARE_HANDLE_ANGLE, must be a valid D3D share handle, cast into the type EGLClientBuffer. The handle may be obtained from the Direct3D9Ex CreateTexture function, from DXGI's GetSharedHandle method on an ID3D10Texture2D, or from the EGL_ANGLE_surface_d3d_texture_2d_share_handle extension." Issues Revision History Version 3, 2011/05/12 - publish Version 2, 2011/05/03 - specify EGL_D3D_TEXTURE_2D_SHARE_HANDLE - specify error if dimensions don't match Version 1, 2011/04/12 - first draft.
