How to Stretch Node Width to Viewport Width in Angular Diagram?

In this article, you can learn about how to stretch a node’s width to the viewport width in an Angular diagram. To stretch a node’s width to fit the viewport width, you can adjust the node size based on the diagram’s viewport settings. The viewportWidth and currentZoom properties within the diagram’s scrollSettings help you calculate the appropriate node width, ensuring it aligns with the visible area of our Angular Diagram feature tour page.

Below Code Snippet explains how to stretch node width to viewport width

public updateImageNode() {
   let node = (this.diagram as any).getObject('headerNode');
   (node as any).width =
     this.diagram.scrollSettings.viewPortWidth +
     this.diagram.scrollSettings.viewPortWidth *
       this.diagram.scrollSettings.currentZoom;

   //to preview zoom in and zoom out
   this.diagram.scrollSettings.maxZoom =
     this.diagram.scrollSettings.currentZoom;
   this.diagram.scrollSettings.minZoom =
     this.diagram.scrollSettings.currentZoom;
 } 

The updateImageNode function sets the headerNode width to account for the viewport width and current zoom. It then locks the zoom level by setting maxZoom and minZoom to the current zoom, maintaining a consistent view.
