PageRenderInitiate and PageRenderComplete event

16 May 20251 minute to read

In Syncfusion PDF Viewer, pageRenderInitiate and pageRenderComplete actions are events that occur during the rendering process of PDF documents.

pageRenderInitiate

The pageRenderInitiate event is triggered when the rendering of a page in the PDF document begins. This event provides developers with an opportunity to perform any necessary initialization or setup before the rendering of the page content commences. It can be utilized to prepare resources, set up rendering parameters, or execute any other actions required before the page rendering process starts.

pageRenderComplete

The pageRenderComplete event is triggered when the rendering of a page in the PDF document is completed. This event allows developers to perform cleanup tasks or finalize rendering-related processes after the rendering of the page content finishes. It can be used to release resources, finalize rendering settings, or handle any post-rendering tasks necessary for the application.

pdfviewer.pageRenderInitiate = args => {
    // This method is called when the page rendering starts
   console.log('Rendering of pages started');
   console.log(args);
 };
 
pdfviewer.pageRenderComplete = args => {
    // This method is called when the page rendering completes
    console.log('Rendering of pages completed');
    console.log(args);
};

The provided code demonstrates how to subscribe to the pageRenderInitiate and pageRenderComplete events in the Syncfusion PDF Viewer component.
