Terminology

Node

Every object on the drawboard is a Node. Typical Nodes are:

• ImageNode, which represents an image.
• TextNode, which represents a piece of text.
• PathNode, which represents the path you draw (with the help of the Brush plugin) on the drawboard 🎨.
• Group, which represents a group of Node.

SingleNode

In the context of carefree-drawboard 🎨, a SingleNode represents one single Node which is not a Group. Which means:

• Multiple Nodes is NOT SingleNode.
• ImageNode is SingleNode.
• TextNode is SingleNode.
• Group is NOT SingleNode.

Pivot

Pivot is an important concept when we need to position our plugins. All supported Pivots are:

• lt: left top corner.
• top: top center.
• rt: right top corner.
• left: middle left.
• center: middle center.
• right: middle right.
• lb: left bottom corner.
• bottom: bottom center.
• rb: right bottom corner.
