<para>Those formats transfer pixel data as RGB values in a cylindrical-coordinate

system using Hue-Saturation-Value or Hue-Saturation-Lightness components. The

format code is made of the following information.

<itemizedlist>

<listitem><para>The hue, saturation, value or lightness and optional alpha

components order code, as encoded in a pixel sample. The only currently

supported value is AHSV.

</para></listitem>
|

<listitem><para>The number of bits per component, for each component. The values
|

can be different for all components. The only currently supported value is 8888.

</para></listitem>

<listitem><para>The number of bus samples per pixel. Pixels that are wider than
|

the bus width must be transferred in multiple samples. The only currently

supported value is 1.</para></listitem>

(PADHI) or low order bits (PADLO).</para></listitem>
