| OpenGL ES Extension #??? |
| |
| Dependencies |
| |
| This extension is written against the OpenGL ES 2.0 Specification. |
| This extension depends on EXT_texture_storage. |
| |
| Overview |
| |
| This allows clients to specify alternative texture backings which support |
| scanout and can be used as hardware overlays. |
| |
| New Tokens |
| |
| Accepted by the <bufferusage> parameter of glTexStorage2DImageCHROMIUM: |
| GL_SCANOUT_CHROMIUM 0x6000 |
| |
| New Procedures and Functions |
| |
| The command |
| |
| void TexStorage2DImageCHROMIUM(enum target, enum internalformat, |
| enum bufferusage, sizei width, |
| sizei height); |
| |
| specifies that the (single) level of the texture is backed by a platform |
| image buffer with the specified usage. The only supported buffer usage is |
| SCANOUT_CHROMIUM which allows the texture to be used for scanout and in |
| hardware overlays. The supported internal formats are RGBA8_OES, |
| BGRA8_EXT, RGBAF16_EXT, and R8_EXT. |
| |
| Errors |
| |
| A context lost will result when this call fails, either because of an |
| invalid parameter value or because of a runtime error such as an out of |
| memory condition. |
