How to Update the ViewPort at Runtime in Angular Diagram?

In this article, you can learn how to update the viewport at runtime in Angular Diagram. You can use the updateViewport() method to dynamically adjust the dimensions of the diagram’s viewport. While loading a saved Angular Diagram, updateViewport() ensures that the viewport correctly aligns with the loaded content, potentially fitting the entire diagram within view. Once the diagram is loaded, it will adjust the viewport size, ensuring the correct rendering of the diagram.

The below code snippet demonstrating how to update the viewport at runtime:

loadDiagram(event: ProgressEvent<FileReader>) {
   const jsonString = event.target?.result as string;
   this.diagram.loadDiagram(jsonString);
   //Updates diagram viewport
   this.diagram.updateViewPort();
 }
