public boolean getThrowExceptionsOnInvalidImages() 
public void setThrowExceptionsOnInvalidImages(boolean value)

public:

ThrowExceptionsOnInvalidImages # get and set (RasterCodecs)

Property Value

A value indicating whether to throw an exception instead of returning a null reference on certain methods of this RasterCodecs object. The default value is true.

Remarks

Some of the methods of this RasterCodecs class will return an object when called. For example, the Load or LoadAsync methods will return the RasterImage object created. If the value of ThrowExceptionsOnInvalidImages is set to true, then the Load or LoadAsync methods return a null reference instead when it encounters an error and cannot return a valid image.

The following methods will either throw an exception or return a null reference depending on the setting of the ThrowExceptionsOnInvalidImages property.

Example

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing; 
using Leadtools.ImageProcessing.Color; 
using Leadtools.Svg; 
 
 
public void ThrowExceptionsOnInvalidImagesExample() 
{ 
   RasterCodecs codecs = new RasterCodecs(); 
 
   // enable codec exceptions 
   codecs.ThrowExceptionsOnInvalidImages = true; 
   try 
   { 
      RasterImage image = codecs.Load("some non-image file"); 
   } 
   catch 
   { 
      Debug.WriteLine("exception caught - sample sucess"); 
   } 
 
   // Clean up 
   codecs.Dispose(); 
}
