GetTotalPages(string) Method

Summary
Gets the number of pages in a disk file image.
Syntax
C#
Objective-C
C++/CLI
Python
public int GetTotalPages( 
   string fileName 
) 
- (NSInteger)totalPagesInFile:(NSString *)file error:(NSError **)error 
public: 
int GetTotalPages(  
   String^ fileName 
)  
def GetTotalPages(self,fileName): 

Parameters

fileName
A String containing the name of the image file to query.

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; 
 
 
public void LoadPagesFromFileTest(string fileName) 
{ 
   // Create a new RasterCodecs instance 
   using (RasterCodecs rasterCodecs = new RasterCodecs()) 
   { 
      rasterCodecs.GetFormat(fileName); 
      // Get the number of pages 
      int pageCount = rasterCodecs.GetTotalPages(fileName); 
      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(fileName, pageNumber)) 
         { 
            Debug.WriteLine("Page {0} loaded", pageNumber); 
         } 
      } 
   } 
}
