fpdf.set_display_mode(zoom, layout: str)Defines the way the document is to be displayed by the viewer. The zoom level can be set: pages can be displayed entirely on screen, occupy the full width of the window, use the real size, be scaled by a specific zooming factor or use the viewer default (configured in the Preferences menu of Adobe Reader). The page layout can be specified too: single page at a time, continuous display, two columns or viewer default.
If this method is not called, the zoom mode is set to fullwidth and the layout is set to continuous by default.
