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