Méthode	Description
Dispose ( ) : void	Disposes all resources used by this instance of the TargaImage class.
LoadTGAHeaderInfo ( BinaryReader binReader, TargaHeader objTargaHeader ) : void	Loads the Targa Header information from the file.
Save ( MemoryStream ms, System.Windows.Media.Imaging.WriteableBitmap img ) : void
TargaImage ( Stream stream, TargaHeader prevHeader = null ) : System	Creates TGA image from stream.
TargaImage ( TargaHeader prevHeader = null ) : System	Creates a new instance of the TargaImage object.
TargaImage ( string strFileName ) : System	Creates a new instance of the TargaImage object with strFileName as the image loaded.

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
LoadFromStream ( byte filebytes ) : MemoryStream
LoadImageBytes ( BinaryReader binReader ) : byte[]	Reads the image data bytes from the file. Handles Uncompressed and RLE Compressed image data. Uses FirstPixelDestination to properly align the image.
LoadTGAExtensionArea ( BinaryReader binReader ) : void	Loads the Targa Extension Area from the file, if it exists.
LoadTGAFooterInfo ( BinaryReader binReader ) : void	Loads the Targa Footer information from the file.
LoadTGAImage ( BinaryReader binReader ) : void	Reads the image data bytes from the file and loads them into the Image Bitmap object. Also loads the color map, if any, into the Image Bitmap.
LoadThumbnail ( BinaryReader binReader, PixelFormat pfPixelFormat ) : void	Loads the thumbnail of the loaded image file, if any.
ToWPF ( ) : System.Windows.Media.Imaging.BitmapSource
