| <d:testDescription xmlns="http://www.w3.org/1999/xhtml" href="http://www.w3.org/TR/SVG11/filters.html#feDisplacementMapElement"> |
| <p> |
| Verify the basic capability to handle the feDisplacementMap filter |
| node. Six images should appear in 2 rows of 3. On the left in each |
| row a test image of a checker board is displayed. In the middle |
| column is the displacement map. In the right-hand column is the |
| result. All displacement maps are generated as png files with gamma |
| 1.0 and must be interpreted linearly for the proper geometric |
| displacement to occur. |
| </p> |
| <p> |
| The top row tests a displacement map which displaces each pixel by an |
| amount equivalent to a rotation of 20 degrees around the center of the |
| image. A blue reference rectangle is drawn on the result using an svg |
| transform attribute to mimick the same 20 degree rotation. The edges |
| of the blue rectangle should be parallel to the grid lines in the |
| displaced image. Distortion of the grid pattern such that the grid |
| lines are slightly curved is indicative of improper gamma handling in |
| the viewer. |
| </p> |
| <p> |
| The bottom row tests a displacement map which distorts the image |
| spherically. |
| </p> |
| <p> |
| In addition to feDisplacementMap, this test uses the 'feImage' and |
| 'rect' elements. Figure labeling uses the text element. The |
| reference blue rectangle uses fill, fill-opacity, and transform. |
| </p> |

| The rendered image should match the reference image. The edges |
| of the blue rectangle must be parallel to the grid lines in the |
| displaced image. The center of the bottommost right distorted image |
| should be on a gridpoint. |
