View mode dialog

ViewModePickerDialogFragment allows users to: pick page layout mode , select page color mode , rotate pages , and crop pages .

To show a view mode dialog in your activity, create a new instance of ViewModePickerDialogFragment by calling newInstance(PagePresentationMode, boolean, boolean, int):

public void ShowViewModeDialog()
{
    var viewModeDialog = pdftron.PDF.Dialog.ViewModePickerDialogFragment.NewInstance(mPdfViewCtrl.PagePresentationMode,
      false, mReflowControl.Visibility == ViewStates.Visible, 0);
    viewModeDialog.SetStyle((int)DialogFragmentStyle.Normal, Resource.Style.PDFTronAppTheme);
    viewModeDialog.Show(this.SupportFragmentManager, "view_mode_picker");
}

In order to let users pick PDF page presentation mode, color mode, etc. you need to implement the corresponding events in the ViewModePickerDialogFragment instance.

viewModeDialog.CustomColorModeSelected += (sender, e) =>
{
    // save the selection so we can retrieve it next time
    PdfViewCtrlSettingsManager.SetCustomColorModeBGColor(this, e.BgColor);
    PdfViewCtrlSettingsManager.SetCustomColorModeTextColor(this, e.TxtColor);
    PdfViewCtrlSettingsManager.SetColorMode(this, PdfViewCtrlSettingsManager.KeyPrefColorModeCustom);
    // Do something with e.BgColor and e.TxtColor
};

viewModeDialog.ViewModeColorSelected += (sender, e) =>
{
    // save the selection so we can retrieve it next time
    PdfViewCtrlSettingsManager.SetColorMode(this, e.ColorMode);
    // Do something with e.ColorMode
};

viewModeDialog.ViewModeSelected += (sender, e) =>
{
    // Do something with e.ViewMode
};

In ViewModeSelected, the selected view mode values are defined in PdfViewCtrlSettingsManager and include the following:
