| <p> |
| This test verifies both the initial viewport size and the support for the various |
| unit specifiers. |
| </p> |
| <p> |
| The units in SVG can be: user coordinate and CSS units: em, ex, px, pt, pc, cm, mm, |
| in and percentages. The test does not check the absolute length accuracy as this |
| can only be truly validated with a ruler. However, it validates that the different |
| units are supported by drawing multiple elements who have the same length specified |
| in different units. |
| </p> |
| <p> |
| The viewport is the "finite rectangular region" where rendering occurs in SVG. |
| Hence, nothing should be rendered outside the viewport (paragraph 7.1). Furthermore, |
| when no positioning properties are set on the top svg element, the initial viewport |
| size should have the value of the top svg element's "width" and "height" attributes. |
| To check this behavior, the test does not define positioning properties on the top |
| svg element but defines its "width" and "height" properties. Then it fills a red |
| rectangle that is bigger than the viewport size. Then, a rectangle, the size of the |
| viewport is drawn in white. If rendering is limited to the viewport area, none of the |
| red should show. |
| </p> |
| <p> |
| The line showing the "ex" units will not necessarily appear with the same length |
| as shown in the reference image because the X-height of a font is not |
| necessarily half of the font size (which is assumed in the reference image where |
| 1ex is considered to be .5em). |
| </p> |

| <d:passCriteria xmlns="http://www.w3.org/1999/xhtml"> |
| <p>The test passes if the top three lines (user units, px, em) are the same length, |
| the fifth line (%) is the same length as the top three lines, and the bottom |
| five lines (in, cm, mm, pt, pc) are the same length. The fourth line (ex) may have |
| any non-zero length, since the X-height of the font will depend on the exact font |
| chosen by the user agent (which may vary).</p> |
