Example
C#
using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing; 
using Leadtools.ImageProcessing.Color; 
using Leadtools.Svg; 
 
 
public void PreloadCodecsExample() 
{ 
   RasterCodecs codecs = new RasterCodecs(); 
 
   string srcFileName1 = Path.Combine(LEAD_VARS.ImagesDir, "Image1.j2k"); 
   string srcFileName2 = Path.Combine(LEAD_VARS.ImagesDir, "Image1.cmp"); 
 
   // display the original values before changing them 
   Debug.WriteLine("PreloadCodecList - {0}", codecs.PreloadCodecsList); 
   Debug.WriteLine("FixedPreloadCodecs - {0}", codecs.FixedPreloadCodecs); 
   Debug.WriteLine("CachedPreloadCodecs - {0}", codecs.CachedPreloadCodecs); 
   Debug.WriteLine("IgnoreCodecList - {0}", codecs.IgnoreCodecsList); 
 
   // preload only the j2k filter and ignore the cmp filter 
   codecs.PreloadCodecs(1, 1, "j2k"); 
   codecs.IgnoreCodecs("cmp"); 
 
   // try to get info on a j2k image 
   CodecsImageInfo info = codecs.GetInformation(srcFileName1, false); 
   Debug.WriteLine("j2k - Width: {0}, Height {1}", info.Width, info.Height); 
 
   // try to get info on a cmp image 
   try 
   { 
      info = codecs.GetInformation(srcFileName2, false); 
   } 
   catch 
   { 
      Debug.WriteLine("GetInformation for cmp failed - sample success!"); 
   }
