| <p>The test pattern to produce.</p> |
| <p>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.</p> |
| <p>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.</p> |
