How to Prevent Node Rotation in Angular Diagram?

In this article, you can learn about how to prevent node rotation in Angular Diagram. In the Syncfusion® Angular Diagram, we have the flexibility to enable or disable specific behaviors of nodes through the use of NodeConstraints.

To prevent the rotation of a node in a diagram, we can use the Rotate NodeConstraint and disable it using the Bitwise ‘&~’ (XOR) operator.

//Set the constraints for node as Rotate and disable it
constraints: NodeConstraints.Default & ~NodeConstraints.Rotate,

Below is a code example demonstrating how to prevent rotation in node :

import {
 DiagramModule,
 DiagramComponent,
 NodeModel,
 NodeConstraints,
} from '@syncfusion/ej2-angular-diagrams';

import { Component, ViewEncapsulation, ViewChild } from '@angular/core';

@Component({
 imports: [DiagramModule],
 providers: [],
 standalone: true,
 selector: 'app-container',
 template: `<ejs-diagram #diagram id="diagram" width="100%" height="580px" [getNodeDefaults] ='getNodeDefaults'>
         <e-nodes>
             <e-node id='node1' [offsetX]=250 [offsetY]=250 [constraints]='nodeConstraints'></e-node>
         </e-nodes>
     </ejs-diagram>`,
 encapsulation: ViewEncapsulation.None,
})
export class AppComponent {
 @ViewChild('diagram')
 public diagram?: DiagramComponent;
 public nodeConstraints?: NodeConstraints;
 ngOnInit(): void {
   this.nodeConstraints = NodeConstraints.Default & ~NodeConstraints.Rotate;
 }
 public getNodeDefaults(node: NodeModel): NodeModel {
   node.height = 100;
   
   node.width = 100;
   return node;
 }
}
