PaperComponent

Provides a component that manages a Paper. You can configure three sets of options on this component:

  1. renderOptions - these are options that control the behaviour of the Paper canvas
  2. viewOptions - these are mappings of node/group types to behaviour and components, and edge types to behaviour
  3. modelOptions - Options that govern how the underlying data model operates. If you don't provide these, the Paper component uses defaults (which is fine for the majority of applications)
@Component({
  selector:"app-my-canvas",
  template:`<vjs-Paper [renderOptions]="renderOptions"
  [viewOptions]="viewOptions"
  [modelOptions]="modelOptions"/>`
})
export class MyCanvas {

  renderOptions = { ... }
  viewOptions = { ... }
  modelOptions = { ... }
}
