public int Page { get; set; }
Public Property Page As Integer
@property (nonatomic, assign) NSInteger page
public int getPage()
public void setPage(int value)
The 1-based index of the current page for this RasterImage.
The RasterImage object can hold multiple pages with different sizes. The AddPage, AddPages, InsertPage and InsertPages methods allows adding new pages to an existing RasterImage.
The RemovePageAt, RemovePages and RemoveAllPages methods allows removing existing pages from a RasterImage object.
The ReplacePage and ReplacePages methods allows replace existing pages in a RasterImage object.
The PageCount property holds the total number of pages in a RasterImage object while the Page property allows you to change the current active page.
The current active page (The page indicated by the Page property) is used by default when accessing the data of a RasterImage object unless otherwise indicated.
This example demonstrates how to deal with multipage RasterImage objects.
