Syntax

C++/CLI

public ImageViewerItem AddFromImage( 
   RasterImage rasterImage, 
   int pageNumber 
)

public:  
   ImageViewerItem^ AddFromImage( 
      RasterImage^ rasterImage, 
      int pageNumber 
   )

Parameters

rasterImage

This method allows you to quickly add an item from a RasterImage. It is the equivalent of the following code:

ImageViewerItem item = new ImageViewerItem(); 
item.Image = rasterImage; 
item.PageNumber = pageNumber; 
imageViewer.Items.Add(item);

If rasterImage is null, then an empty item is added.

_imageViewer.Items.AddFromImage(image, 1);
