+       <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
