<title>HSV/HSL Formats</title>
<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>
<listitem><para>The bus width.</para></listitem>
<listitem><para>For formats where the total number of bits per pixel is smaller
than the number of bus samples per pixel times the bus width, a padding
value stating if the bytes are padded in their most high order bits
(PADHI) or low order bits (PADLO).</para></listitem>
<listitem><para>For formats where the number of bus samples per pixel is larger
than 1, an endianness value stating if the pixel is transferred MSB first
(BE) or LSB first (LE).</para></listitem>
</itemizedlist>
