Public Methods

Method	Description
FromFile ( string filename, Size size, UseEmbeddedThumbnails useEmbeddedThumbnails, bool useExifOrientation, bool useWIC ) : Image	Creates a thumbnail from the given image file.
FromImage ( Image image, Size size, UseEmbeddedThumbnails useEmbeddedThumbnails, bool useExifOrientation, bool useWIC ) : Image	Creates a thumbnail from the given image.

Private Methods

Method	Description
ConvertToBitmap ( System.Windows.Media.Imaging.BitmapSource sourceWpf ) : Bitmap	Converts BitmapSource to Bitmap.
GetMetadataObject ( BitmapMetadata metadata ) : object	Returns the metadata for the given query.
GetRotation ( System.Windows.Media.Imaging.BitmapFrame frameWpf ) : int	Returns Exif rotation in degrees. Returns 0 if the metadata does not exist or could not be read. A negative value means the image needs to be mirrored about the vertical axis.
GetRotation ( Image img ) : int	Returns Exif rotation in degrees. Returns 0 if the metadata does not exist or could not be read. A negative value means the image needs to be mirrored about the vertical axis.
GetRotation ( string filename ) : int	Returns Exif rotation in degrees. Returns 0 if the metadata does not exist or could not be read. A negative value means the image needs to be mirrored about the vertical axis.
GetThumbnail ( System.Windows.Media.Imaging.BitmapFrame bmp, Size size, UseEmbeddedThumbnails useEmbeddedThumbnails, int rotate ) : Image	Creates a thumbnail from the given bitmap.
GetThumbnailBmp ( Image image, Size size, int rotate ) : Image	Creates a thumbnail from the given image.
GetThumbnailBmp ( string filename, Size size, UseEmbeddedThumbnails useEmbeddedThumbnails, int rotate ) : Image	Creates a thumbnail from the given image file.
ScaleDownRotateBitmap ( System.Windows.Media.Imaging.BitmapSource sourceWpf, double scale, int angle ) : System.Windows.Media.Imaging.BitmapSource	Scales down and rotates a Wpf bitmap.
ScaleDownRotateBitmap ( Image source, double scale, int angle ) : Image	Scales down and rotates an image.
