+ *
+ * The test pattern to produce.
+ *
+ * The Gamut pattern creates a checkerboard pattern of colors at the
+ * edge of the YCbCr gamut and nearby colors that are out of gamut.
+ * The pattern is divided into 4 regions: black, white, red, and blue.
+ * After conversion to RGB, the out-of-gamut colors should be converted
+ * to the same value as their in-gamut neighbors. If the checkerboard
+ * pattern is still visible after conversion, this indicates a faulty
+ * conversion. Image manipulation, such as adjusting contrast or
+ * brightness, can also cause the pattern to be visible.
+ *
+ * The Zone Plate pattern is based on BBC R&D Report 1978/23, and can
+ * be used to test spatial frequency response of a system. This
+ * pattern generator is controlled by the xoffset and yoffset parameters
+ * and also by all the parameters starting with 'k'. The default
+ * parameters produce a grey pattern. Try 'videotestsrc
+ * pattern=zone-plate kx2=20 ky2=20 kt=1' to produce something
+ * interesting.
