||
|
|
[page:Function onProgress] — (optional) A function to be called while the loading is in progress. The argument will be the XMLHttpRequest instance, which contains [page:Integer total] and [page:Integer loaded] bytes.<br />
|
||
|
|
[page:Function onError] — (optional) A function to be called if an error occurs during loading. The function receives the error as an argument.<br />
|
||
|
|
</p>
|
||
|
|
<p>
|

|
<h3>[method:Array createShapes]( [param:ShapePath shape] )</h3>
|
||
|
|
<p>
|
||
|
|
[page:ShapePath shape] — A ShapePath from the array of [page:ShapePath], given as argument in the onLoad function for the load function of [page:SVGLoader].<br />
|
||
|
|
</p>
|
||
|
|
<p>
|
||
|
|
Returns one or more [page:Shape] objects created from the [param:ShapePath shape] provided as an argument in this function.
