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.
