| '''OpenGL extension OES.EGL_image |
| |
| This module customises the behaviour of the |
| OpenGL.raw.GLES2.OES.EGL_image to provide a more |
| Python-friendly API |
| |
| Overview (from the spec) |
| |
| This extension provides a mechanism for creating texture and |
| renderbuffer objects sharing storage with specified EGLImage objects |
| (such objects are referred to as "EGLImage targets"). |
| |
| The companion EGL_KHR_image_base and EGL_KHR_image extensions |
| provide the definition and rationale for EGLImage objects. |
| |
| Other EGL extensions, such as EGL_KHR_gl_texture_2D_image, |
| EGL_KHR_gl_texture_cubemap_image, EGL_KHR_gl_texture_3D_image, |
| EGL_KHR_gl_renderbuffer_image, and EGL_KHR_vg_parent_image, define |
| the related functionality of creating EGLImage objects from |
| "EGLImage sources" such as OpenGL ES texture or renderbuffers or |
| OpenVG VGImage objects. |
| |
| EGL extension specifications are located in the EGL Registry at |
| |
| http://www.khronos.org/registry/egl/ |
| |
| The official definition of this extension is available here: |
| http://www.opengl.org/registry/specs/OES/EGL_image.txt |
