The .getDiagramContent() method returns a clipped diagram when called on a zoomed-in diagram.

Hi Syncfusion Team,

I'm using the latest version of diagram component in my app:"@syncfusion/ej2-angular-diagrams": "^17.3.34".

Since my diagram app uses SVG nodes. I have to call .getDiagramContent() and send it to a htmlToPdfConverter before I print/export it.

I've noticed that when my diagram is zoomed-in, the output of .getDiagramContent() shows a clipped diagram (clipped per original/unzoomed diagram's height, width dimensions). 

Please see the following attached files: 
  • zoom-none.png: original diagram with width: 900, height: 500 and zoomlevel: 1.
  • zoom-none-getDiagramContent.html: html string output from calling .getDiagramContent() on above diagram.
  • zoom-none-saveDiagram.JSON: json string output from calling .saveDiagram on above diagram.
  • zoom-144-png: zoomed-in diagram with width: 1296, height: 720 and zoomlevel: 1.44
  • zoom-144-getDiagramContent.html: html string output from calling .getDiagramContent() on above diagram
  • zoom-144-saveDiagram.JSON: json string output from calling .saveDiagram on above diagram.
As a result, I'm unable to print/export a zoomed-in diagram. 

I have to zoom back out (to ZoomLevel: 1) in order to get the diagram to print correctly.

Can you please confirm if this is a bug in .getDiagramContent() or whether I'm making some mistake in my app implementation.

Thanks,
Mithun

Hi Mithun, 
 
We have checked in our sample by zooming the diagram. We are unable to replicate an issue at our end. Could you please check in the below sample? Also, could you please upgrade our diagram control to the latest version 17.4.42 and check at your end?
