Méthodes protégées

Méthode	Description
Dispose ( bool disposing ) : void	Dispose(bool disposing) executes in two distinct scenarios. If disposing equals true, the method has been called directly or indirectly by a user's code. Managed and unmanaged resources can be disposed. If disposing equals false, the method has been called by the runtime from inside the finalizer and you should not reference other objects. Only unmanaged resources can be disposed.

Private Methods

Méthode	Description
ClearAll ( ) : void	Clears out all objects and resources.
GetPixelFormat ( ) : PixelFormat	Gets the PixelFormat to be used by the Image based on the Targa file's attributes
