Delegate method that is used to request a page and provide the requested page to the caller method.
Syntax
public delegate void PageRequestCallback(
PageRequestCallbackData data
)
Public Delegate Sub PageRequestCallback( _
ByVal data As PageRequestCallbackData _
)
public interface PageRequestCallback
public delegate void PageRequestCallback(
PageRequestCallbackData^ data
)
data
An instance of the PageRequestCallbackData interface containing the requested image information.
This delegate is useful when the number of form pages is not known before recognizing the form or when the users does not want to load all image pages in the memory or load them via network while he needs to process few of them. So the user loads the first page of the form and uses it for recognition, then for processing he will be asked to provide only the pages that have processing fields.
For an example, refer to AutoFormsEngine.Run(RasterImage form, PageRequestCallback pageRequestCallback, Object userData, List<IMasterFormsCategory>).
