Attribute Types

The attributes of the node are edited on the Attributes Panel in the Control Panel.

Data

Some nodes require larger blocks of information to be able to process the output image. This information is the Node Data and is edited by the user in the node's user interface. The curves attributes in the [Curves node](NodesAdjustCurve.html], and the shapes attributes in the Shapes node are examples of Node Data.

Common Attributes

All nodes share the following common attributes:

Enable - Disable
Nodes that are enabled are processed by the node graph, they receive their input values, modify them, and return them as output.
Nodes that are disabled are not processed by the node graph. Nodes that generate images stop generating their images. Nodes that modify the image, stop modifying the image and don't change it at all.
Select some nodes and hit the E key to Enable or Disable them.

Name
The name of the node. The name is displayed on the title of the node in the node graph.

Description
A short description for the node. The description is shown as a tooltip when the mouse hover over the node in the node graph.
