Syntax

C++

public ImageViewerItem AddFromImage( 
   RasterImage rasterImage, 
   int pageNumber 
)

Public Function AddFromImage( 
   ByVal rasterImage As RasterImage, 
   ByVal pageNumber As Integer 
) As ImageViewerItem

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

Parameters

rasterImage

Source image.

pageNumber

1-based page number of rasterImage. Pass 1 if rasterImage contains a single page (frame).

Return Value

Remarks

Use AddFromSvgDocument to add an item from an SVG document.

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.
