	<para>The following four pixel formats are raw sRGB / Bayer formats

	with 10 bits per colour compressed to 8 bits each, using DPCM

	compression. DPCM, differential pulse-code modulation, is lossy.

	Each colour component consumes 8 bits of memory. In other respects

	this format is similar to <xref

	linkend="pixfmt-srggb10">.</xref></para>
