A value indicating whether to throw an exception instead of returning a null reference on certain methods of this RasterCodecs object.
public bool ThrowExceptionsOnInvalidImages { get; set; }
Public Property ThrowExceptionsOnInvalidImages As Boolean
public boolean getThrowExceptionsOnInvalidImages()
public void setThrowExceptionsOnInvalidImages(boolean value)
A value indicating whether to throw an exception instead of returning a null reference on certain methods of this RasterCodecs object.
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.
