Rotate document pages in Xamarin

This tutorial only applies to Xamarin.Android.

The RotateDialogFragment allows users to rotate pages of the opened document by 90, 180 and 270 degrees. It also displays a thumbnail of the current page at the selected rotation angle.

Show rotate page dialog

To show a rotate pages dialog in your activity, create a new instance of RotateDialogFragment by calling newInstance() and setting the PDFViewCtrl:

public void showRotateDialog()
{
    pdftron.PDF.Dialog.RotateDialogFragment.NewInstance()
        .SetPdfViewCtrl(mPdfViewCtrl)
        .Show(this.SupportFragmentManager, "rotate_pages_dialog");
}
