GetTotalPages(Uri) Method

Summary
Gets the number of pages of an image URI.
Syntax
C#
C++/CLI
Python
public int GetTotalPages( 
   Uri uri 
) 
public: 
int GetTotalPages(  
   Uri^ uri 
)  
def GetTotalPages(self,uri): 

Parameters

uri
The Uri containing the image data.

Return Value

Number of pages in the specified file.

Remarks

GetInformation and GetFormat use GetInformation internally. So, if more information about the image is required, it is recommended to call GetInformation directly and obtain the data once.

Example
C#
using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing; 
using Leadtools.ImageProcessing.Color; 
using Leadtools.Svg; 
 
 
private static void LoadPagesFromUriTest(Uri uri) 
{ 
   // Create a new RasterCodecs instance 
   using (RasterCodecs rasterCodecs = new RasterCodecs()) 
   { 
      rasterCodecs.GetFormat(uri); 
      // Get the number of pages 
      int pageCount = rasterCodecs.GetTotalPages(uri); 
      Debug.WriteLine("Number of pages in the file is {0}", pageCount); 
 
      // Load all pages 
      for (int pageNumber = 1; pageNumber <= pageCount; pageNumber++) 
      { 
         using (RasterImage rasterImage = rasterCodecs.Load(uri, pageNumber)) 
         { 
            Debug.WriteLine("Page {0} loaded", pageNumber); 
         } 
      } 
   } 
}
