Custom XML-based Vector Objects
Just like the gradients, WebPhotoStudio objects are defined using the powerful XML language. This makes it really simple to create custom objects.
Here is a simple sample object - many more complex objects are included with WebPhotoStudio.
<star name="Star 1">
<coords>0,0,1,1</coords>
<subdivision>4</subdivision>
<internalradius>0.15</internalradius>
<stroke>
<width>1</width>
</stroke>
<fill>
</fill>
</star>
The WebPhotoStudio manual features a full reference guide to help you to create your custom objects.
