Ot_page_transitionThe type of animation. Nil means there is no animation. Forward means going forward in history or loading a new page. Normally we will see a page come from the right side and cover the current page. Backward means going backward in history. In this case, the current page moves to the right side in order to display the page covered by it.
module type PAGE_TRANSITION_CONF = sig ... endSuppose that screenshots are stored in objects of type screenshot. Users need to provide a module which specifies the type screenshot (e.g. string) and a function screenshot_container that creates a html element from the screenshot.
module Make (Conf : PAGE_TRANSITION_CONF) : sig ... endinstall_global_handler t take_screenshot animation_type creates a global onchangepage handler which is registered recursively and applies to all pages. t is the transition duration of the animation. take_screenshot callback takes a screenshot of the current page and then calls callback. A callback function is used here because take_screenshot is usually asynchronous. animation_type ev decides the type of the animation of page transition in an onchangepage event.
val install_global_handler_withURI :
?transition_duration:float ->
take_screenshot:((string -> unit) -> unit) ->
animation_type:(Eliom_client.changepage_event -> animation) ->

unitinstall_global_handler_withURI enables you to skip the step of creating a module of type PAGE_TRANSITION_CONF when screenshots are stored as a data uri.
