</div><div><br></div></div></blockquote><div><br></div></div></div><div>Jothy,</div><div><br></div><div>I don't see an example about vtkImageMapToColors on the wiki. Care to add one :) ?</div><div><br clear="all">Thanks,<br>
<br></div><div>David</div></div></div>
<br><br></blockquote></div></div></div></blockquote><div class="gmail_quote"><br></div><div class="gmail_quote">Great, thanks! You'll need to do the following:</div><div class="gmail_quote"><br></div><div class="gmail_quote">
1) Create a login/user for the wiki (maybe you have already done this?)</div><div class="gmail_quote">2) Click [edit] in the section you want to add something to</div><div class="gmail_quote">3) Create a new page and a link to the new page by adding:</div>
<div class="gmail_quote">* [[VTK/Examples/NewPageName | What you want to display as the link]]</div><div class="gmail_quote">4) when you save these changes, there will now be a red link. When you click this link, it immediately brings you to the "edit" page of the new page</div>
<div class="gmail_quote">5) add the content and save it</div><div class="gmail_quote">6) the link automatically turns blue (so it now goes to the "page" page instead of the "edit" page)</div><div class="gmail_quote">
<br></div><div class="gmail_quote">Let me know if you have any problems - if you do, lets modify this set of instructions so it is followable by a new wiki contributor and I'll add it as a "how to contribute" section. Also, let me know when you do the first one and I'll check it out for style, etc.</div>
<br clear="all">Thanks,<br><br><div>David</div></div>
