boundsInViewport Property

Summary

The position and size of the document page when PrintDocumentOptions.UseViewportLayout is true.

Syntax
TypeScript
JavaScript
Object.defineProperty(DocumentPrintPageData.prototype, 'boundsInViewport', 
	get: function(), 
	set: function(value) 
) 
boundsInViewport: LeadRectD; 

Property Value

A LeadRectD representing the bounds of the document page to be composed into DocumentPrintData.ViewportImage. If PrintDocumentOptions.UseViewportLayout is false, the value is LeadRectD.Empty.

Remarks

When PrintDocumentOptions.UseViewportLayout is true and DocumentPrintData.BuildPrintRoot is called at the completion of DocumentViewer.Print, DocumentPrintData.BuildViewportImage will be called to assemble a single DocumentPrintData.ViewportImage that will contain all the printing image data.

Each BoundsInViewport, computed at the start of DocumentViewer.Print, will be used to position the image data in the larger composed HTMLImageElement. The BoundsInViewport is in viewport units, relative to 0,0. DocumentPrintData.ViewportSize is available for reference as the size of the ImageViewer.ControlSize.

For more information, refer to DocumentViewer.Print.
