| EGL Extension ### |
| |
| Dependencies |
| |
| Requires support for the following extension |
| - EGL_EXT_gl_colorspace_display_p3 |
| - EGL_EXT_gl_colorspace_display_p3_linear |
| - EGL_EXT_gl_colorspace_display_p3_passthrough |
| - EGL_EXT_gl_colorspace_scrgb |
| - EGL_EXT_gl_colorspace_scrgb_linear |
| Refer to the above specifications for indirect dependencies. |
| |
| Overview |
| |
| On Android, the support for colorspace extensions listed above are determined |
| based on - |
| 1. The EGL implementation supporting EGL_KHR_gl_colorspace extension |
| 2. Device's display supporting wide color gamut |
| |
| In such cases the Android EGL loader handles the implementation of the above |
| extensions. However, vendors using ANGLE as their EGL/GLES implementations, |
| which layers GLES APIs over Vulkan, need to know the value of these colorspace |
| attributes in order to create Vulkan swapchain images or other images with the |
| appropriate colorspace flags. |
| |
| This extension allows ANGLE's EGL implementation to rely on the Android EGL loader |
| to support and implement the above extensions with the exception that ANGLE's EGL |
| implementation will passthrough, without generating validation errors, the colorspace |
| attribute values introduced by the extensions listed above, to the underlying Vulkan |
| implementation. |
| |
| For details about colorspace and related terminology please refer to the extensions |
| listed in the "Dependencies" section. |
