 * @GST_VIDEO_TEST_SRC_COLORS: All colors

 *

 * 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.
