dispose Method

Summary

Disposes the elements and data for this printing page.

Syntax
TypeScript
JavaScript
DocumentPrintPageData.prototype.dispose = function() 
dispose(): void; 

Remarks

By default, PrintDocumentOptions.AutoDispose is true, dictating that the most recent DocumentPrintData will be disposed with DocumentPrintData.Dispose when a new DocumentViewer.Print begins. This disposal will also call Dispose for each page.

It is important to dispose the page elements when using PrintDocumentOptions.UsePDFClientRendering, as Blob URLs may be used for the image data and not revoking them could cause memory leaks.

All properties of DocumentPrintPageData are get and set, so PageElement and AnnotationsElement can be set to null to avoid disposal if the user intends to reuse them.

For more information, refer to DocumentViewer.Print.
