Summary

Gets the number of items in Buffer.

Syntax

Objective-C

C++/CLI

Java

Python

public int Count { get; }

@property (nonatomic, assign, readonly) NSUInteger count;

public int getCount()

public: 
property int Count { 
   int get(); 
}

Count # get  (CodecsEnumGeoKeysEventArgs)

Property Value

The number of items in the Buffer buffer. Note that this does not describe the number of bytes. For example, Count is 10 and MetadataType is RasterTagMetadataDataType.Double, you will need 10 x 8 = 80 bytes to read the tag data. The default value is 0.

You can also construct a new RasterTagMetadata object from the data stored in this CodecsEnumGeoKeysEventArgs using the ToRasterTagMetadata method.

Example

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing; 
using Leadtools.ImageProcessing.Color; 
using Leadtools.Svg; 
 
 
 
IList<RasterTagMetadata> myGeoKeys; 
 
 
void EnumGeoKeysExample(string srcFileName, string destFileName) 
{ 
   RasterCodecs codecs = new RasterCodecs(); 
 
   geoKeySrcFileName = srcFileName; 
   myGeoKeys = new List<RasterTagMetadata>(); 
 
   codecs.GeoKeyFound += new EventHandler<CodecsEnumGeoKeysEventArgs>(codecs_GeyKeyFound); 
   codecs.EnumGeoKeys(srcFileName, 1); 
   codecs.GeoKeyFound -= new EventHandler<CodecsEnumGeoKeysEventArgs>(codecs_GeyKeyFound); 
 
   // We read all the tags now, save them to the file 
   Debug.WriteLine("{0} GeoKeys read, saving them to the destination file", myGeoKeys.Count); 
   codecs.WriteGeoKeys(destFileName, 1, myGeoKeys); 
 
   // Clean up 
   codecs.Dispose(); 
} 
 
void codecs_GeyKeyFound(object sender, CodecsEnumGeoKeysEventArgs e) 
{ 
   Debug.WriteLine("GeoKey: Id={0}, Count={1}, Type={2}, Data Length={3}, Data=, Cancel={4}", e.Id, e.Count, e.MetadataType, e.Buffer.Length, e.Cancel); 
 
   // Load this GeoKey 
   RasterCodecs codecs = sender as RasterCodecs; 
   RasterTagMetadata geoKey = codecs.ReadGeoKey(geoKeySrcFileName, 1, e.Id); 
   byte[] data = geoKey.GetData(); 
   for (int i = 0; i < data.Length; i++) 
      Debug.WriteLine("{0:X} ", data[i].ToString()); 
 
   // Add it to our collection 
   myGeoKeys.Add(geoKey); 
   e.ToRasterTagMetadata(); 
}
