Custom Component Shapes

Fully customize appearance of components in diagrams.

Usage

Shape registration in the Appmixer SDK:

var appmixer = new Appmixer({
    componentShapes: {
        action: myCustomComponentShape,
        trigger: myCustomComponentShape,
        myUniqueShape: myCustomComponentShape
    },
});

Use "action" and "trigger" keys to override defaults. You can define custom shape for any component in the system, shape reference in a component manifest looks like this:

{
    shape: "myUniqueShape"
}

Built-in shapes are action, trigger, actionVertical and triggerVertical.
