« SVG Attribute reference home
The clip-rule attribute only applies to graphics elements that are contained within a <clipPath> element. The clip-rule attribute basically works as the fill-rule attribute, except that it applies to <clipPath> definitions.
The following fragment of code will cause an evenodd clipping rule to be applied to the clipping path because clip-rule is specified on the <path> element that defines the clipping shape:
html
<
g>
<
clipPath id
=
"
MyClip"
>
<
path d
=
"
..."
clip-rule
=
"
evenodd"
/>
</
clipPath>
<
rect clip-path
=
"
url(#MyClip)"
...
/>
</
g>
whereas the following fragment of code will not cause an evenodd clipping rule to be applied because the clip-rule is specified on the referencing element, not on the object defining the clipping shape:
html
<
g>
<
clipPath id
=
"
MyClip"
>
<
path d
=
"
..."
/>
</
clipPath>
<
rect clip-path
=
"
url(#MyClip)"
clip-rule
=
"
evenodd"
...
/>
</
g>
As a presentation attribute, it also can be used as a property directly inside a CSS stylesheet
Rule 1: Entry Production
The student must operate all software and equipment in the development of the website.
You may use professional photographs, graphics, video, recorded music, etc. within the site. Such items must be integrated into the website, and proper credit must be given within the site as well as in the annotated bibliography.
Note: Using objects created by others specifically for use in your entry violates this rule. For example, adding viewer comments or using a graphic that others produced at your request is not permitted however, using graphics, multimedia clips, etc., that already exist is acceptable.
Rule 2: Size Requirements
The entire site, including all multimedia, may use up no more than 100MB of file space.
Also excluded are words found in materials used for identifying illustrations or used to briefly credit the sources of illustrations and quotations; recurring menus, titles, and navigation instructions; required word count notifications; words within primary documents and artifacts; and the annotated bibliography and process paper, which must be integrated into the site. The process paper is limited to 500 words.
Code used to build the site, and alternate text tags on images do not count toward the word limit.
Website entries may contain no more than 1,200 visible, student-composed words.
Rule 3: Navigation
One page of the website must serve as the“home page.” The home page must include the names of participants, entry title, division, number of student-composed words in the website, number of words in the process paper, and the main menu that directs viewers to the various sections of the site.
Rule 4: Documents and Multimedia
The website may contain documents (e.g. newspaper articles, excerpts from written text, etc.), but the document must be contained within the website.
The website may contain multimedia clips (audio, video, or both) that total no more than four minutes (e.g., use one four-minute clip, four one-minute clips, two two-minute clips, etc.). Included in the four-minute total is any music or songs that play after a page loads.
You may record quotes and primary source materials for dramatic effect, but you may not narrate your own compositions or other explanatory material.
If you use any form of multimedia that requires specific software to view (e.g., Flash, QuickTime, Real Player, etc.), you must provide on the same page a link to an Internet site where the software is available as a free, secure, and legal download.
You may not use embedded material or link to external websites, other than described in the preceding bullet.
Judges will make every effort to view all multimedia content, but files that cannot be viewed cannot be evaluated as part of the entry.
