|
|
<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).
|

<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>
