2.2 Creating a minimal graph
Most nodes have little circles on their left and right edges called anchors. These anchors are used to connect nodes together. Anchors on the left side of a node are used for connecting input images. The node then processes these input images to produce output images that are represented by the anchors on the right. By connecting different nodes together you form a graph where each node makes a change to an image. The nodes that make up the graph can be inserted, modified, and removed in any order and at any time. Together, this promotes a fully non-destructive workflow.
Let’s create a very simple graph. As nodes are connected together, graphs tend to flow from left to right. Move the Image Open node by left clicking and dragging it by the title bar to the left of the Render Node. A node’s title bar is the dark region at the top with wording that describes what type of node it is.
Connect the two nodes by left clicking and holding the left mouse button on the “Image” anchor on the right side of the Image Open node. Drag your mouse over to the “Image” anchor on the left side of the Render node before releasing the button. Done correctly, a connection between the two nodes will be created.
Your minimal graph is complete! The image you imported earlier is passed directly to the Render node. The Render node is a special node that always exists and has one input anchor. The image connected to the Render node is the image that is exported when you are done editing with Phoduit.
