Functions

Detailed Description

Currently a layer acts only as a group so that you can organize shapes and control in which order they are rendered. To add a new item to the layer, use the addItem(item) or the insertItem(item) function.

To remove an item from the layer, use the removeItem(item) function.

Items in a layer are rendered from top to bottom, meaning the bottom-most items will always be drawn on top of other items.
