    <p><strong>Edit:</strong> </p> <p>There's a rough workaround for this that doesn't require hacking Raphael core code, but does depend on a not completely stable IE bug, described <a href="https://github.com/DmitryBaranovskiy/raphael/issues/177" rel="nofollow">https://github.com/DmitryBaranovskiy/raphael/issues/177</a></p> <p>It works by hiding the SVG pattern object from Raphael by renaming it in the Raphael object, causing <code>updatePosition()</code> to not be called. This stops Raphael moving the background image in SVG mode. In VML mode, IE8 has a bug whereby, even though the code moves the <code>&lt;fill&gt;</code> element, this isn't updated on the screen until a redraw is forced.</p> <pre><code>path.patternTmp = path.pattern; delete path.pattern; </code></pre> <p>This has the same other downside as the suggestion below that in VML mode it relies on an IE bug. But it works for simple cases. I haven't tested fully enough to see if there are other side effects of this fix, but there shouldn't be - looked at Raphael's source code, it looks like <code>updatePosition()</code> is the only Raphael function that uses <code>element.pattern</code>.</p> <h2><a href="http://jsbin.com/oxuyeq/10/edit" rel="nofollow">http://jsbin.com/oxuyeq/10/edit</a></h2> <p>Note that <code>path.pattern</code> has to be renamed like this every time an image fill is applied - so if you reapply the fill for any reason, you need to re-do this fix - and that re-applying the fill will 'fix' the IE bug we depend on causing the image to slip out of sync with the object.</p> <hr> <p><strong>Original answer:</strong> Here's a sort-of fix. It's ugly in two ways:</p> <ul> <li>For SVG, it relies on hacking Raphael core code (but only a small hack)</li> <li>For VML, it relies on an Internet Explorer redraw bug, and will fail if your code causes a redraw</li> </ul> <p>But you can get relative positions, so long as your code doesn't trigger an IE redraw (e.g. by re-setting the element's fill).</p> <p>Ideally, there would be a way of doing this that works robustly in IE VML rather than relying on a bug.</p> <hr> <p>You can do this ugly almost-fix by <strong>turning off the Raphael function <code>updatePosition()</code> somehow</strong>. The behaviour described above isn't an SVG default, it's a Raphael feature defined in the <code>updatePosition()</code> function which appears to be designed to make Raphael SVG elements' behaviour match how VML elements <em>would</em> behave if Internet Explorer wasn't a bundle of bugs held together with bugs. Note that the <code>updatePosition()</code> function is <em>only</em> called in SVG mode - VML fills are <em>supposed</em> to behave this way by default (but don't reliably because of the redraw bug described in the above linked question...).</p> <p>My (ugly) way of doing this is to modify the <code>updatePosition()</code> function code to this:</p> <pre><code>updatePosition = function (o) { if(!o.relativeFill) { // &lt;&lt;&lt; added this condition var bbox = o.getBBox(1); $(o.pattern, {patternTransform: o.matrix.invert() + " translate(" + bbox.x + "," + bbox.y + ")"}); } }, </code></pre> <p>...then, for each element you want to have a relative fill, you set <code>someElement.relativeFill = true;</code></p> <hr> <p>Note that <strong>this isn't good practice</strong> - e.g. a future Raphael update might use the relativeFill namespace for something else. It's just an example of a sticky plaster fix that (just about) works.</p> <hr> <p><strong>re. VML mode:</strong> In theory, you might be able to make this fix robust and not bug dependent by adding a similar condition to the place in the VML-mode Raphael functions <code>setFillAndStroke</code> and/or <code>setCoords</code> that set <code>fill.position</code> to a dynamic calculation. These seem to be the VML equivalent of <code>updatePosition()</code>. In theory, VML should by default set the fill relative to the shape so long as <a href="http://msdn.microsoft.com/en-us/library/bb229597%28v=vs.85%29.aspx" rel="nofollow"><code>alignshape = true</code> for the fill element, which in theory should be true by default</a>.</p> <p>But, it doesn't seem to work like that in practice. From my testing, relying on the IE bug as above actually seems to be <em>more</em> robust than trying to get IE VML to work as documented. In my testing, it's quite difficult to get IE8 to redraw the fill: only resetting the fill seems to do it.</p>
