Right to Left Scrolling support

You can choose to change the scrolling direction to Right-to-Left if you require so for your document or language.

Right-to-left support (RTL) in Xamarin.Android

To support right-to-left (RTL) language documents, the Apryse SDK provides a high-level API for changing the reading direction of documents in your document viewer.

If you are using DocumentActivity or PdfViewCtrlTabHostFragment2, you can enable right-to-left (RTL) support in your document viewer by setting it with ViewerConfig:

1//@data {"m":true}//
2ViewerConfig.Builder builder = new ViewerConfig.Builder();
3ViewerConfig config = builder
4    .FullscreenModeEnabled(true)
5    .MultiTabEnabled(true)
6    .DocumentEditingEnabled(true)
7    .LongPressQuickMenuEnabled(true)
8    // ...
9    .RightToLeftModeEnabled(true)   // Enable RTL mode, must also call showRightToLeftOption
10    .ShowRightToLeftOption(true)    // Show RTL toggle button in view mode dialog
11    .Build();

Note that if you call rightToLeftModeEnabled you must also call showRightToLeftOption in order for right-to-left (RTL) mode to be enabled.

If you would like more granular control over your document viewer, you can enable right-to-left (RTL) directly in PDFViewCtrl by calling PDFViewCtrl.setRightToLeftLanguage(true).
