| Packed RGB formats |
| ****************** |
| |
| Description |
| =========== |
| |
| These formats are designed to match the pixel formats of typical PC |
| graphics frame buffers. They occupy 8, 16, 24 or 32 bits per pixel. |
| These are all packed-pixel formats, meaning all the data for a pixel lie |
| next to each other in memory. |

| .. note:: Bit 7 is the most significant bit. |
| |
| The usage and value of the alpha bits (a) in the ARGB and ABGR formats |
| (collectively referred to as alpha formats) depend on the device type |
| and hardware operation. :ref:`Capture <capture>` devices (including |
| capture queues of mem-to-mem devices) fill the alpha component in |
| memory. When the device outputs an alpha channel the alpha component |
| will have a meaningful value. Otherwise, when the device doesn't output |
| an alpha channel but can set the alpha bit to a user-configurable value, |
| the :ref:`V4L2_CID_ALPHA_COMPONENT <v4l2-alpha-component>` control |
| is used to specify that alpha value, and the alpha component of all |
| pixels will be set to the value specified by that control. Otherwise a |
| corresponding format without an alpha component (XRGB or XBGR) must be |
| used instead of an alpha format. |
| |
| :ref:`Output <output>` devices (including output queues of mem-to-mem |
| devices and :ref:`video output overlay <osd>` devices) read the alpha |
| component from memory. When the device processes the alpha channel the |
| alpha component must be filled with meaningful values by applications. |
| Otherwise a corresponding format without an alpha component (XRGB or |
| XBGR) must be used instead of an alpha format. |
| |
| The XRGB and XBGR formats contain undefined bits (-). Applications, |
| devices and drivers must ignore those bits, for both |
| :ref:`capture` and :ref:`output` devices. |
