NodeBox automatically converts between types of ports. The background color of a node is the color of its output type. They are the primary visual building blocks of NodeBox. They contain information about curves, lines and points. They are used to specify logical conditions: whether something is enabled or visible, whether elements need to be filtered out or not, etc. Booleans are values that can be either true or false.They are used to specify color information: the fill color of an object, the stroke color of a line, etc. Colors contain red, green and blue values.They are used to specify a place in 2D space: the position of a rectangle, the scale of an object, etc. Points are two-dimensional coordinates in space.They are used wherever we need textual input: the filename of a SVG file, the lookup value for a CSV file or the text in a textpath node. They are used to specify amounts: 10 copies, 50 points, etc. Integer numbers are numbers without a fractional part.They are used to specify dimensions: the width / height of an object, the distance between two points, etc. Floating-point numbers are numbers with a fractional part.Port TypesĮach port expects a certain type of values: The values for the width and height ports come from another node. Whenever a port is connected, the port view indicates that the value for this port comes from another node: Ports are displayed both in the port view (vertically) and the network view (horizontally). ![]() The input ports are also displayed in the port view: The input and output ports of a node are displayed in the network view. A node takes data in from its inputs, processes it, and sets a value in its output port, ready to be picked up by the next node. Ports represent the inputs and output of a node. Nodes can send data to each other using their ports. You can render a node by double-clicking it. The rendered node is the one that’s displayed in the viewer. We can examine what each worker node is doing by changing the rendered node. This is also a filter node, it filters the colored rectangle node. It takes the output of the color node and changes its rotation.
