Customize PDFViewCtrl

PDFTron SDK uses a viewing UI component developed in-house that you can customize.

Customization PDFViewCtrl

This tutorial only applies to Xamarin.Android. See Xamarin.iOS equivalent here.

The PDFViewCtrl has a large API set that can be used to control how the PDF is presented to the user. This guide highlights some of the most commonly used functionality.

If you are using a DocumentActivity (or PdfViewCtrlTabHostFragment), the contained PDFViewCtrl can be customized through PDFViewCtrlConfig.
