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.

|
**Byte Order.**
|
|
Each cell is one byte.
