Method	Description
Scale2 ( Bitmap bitmap, uint trY = 48, uint trU = 7, uint trV = 6, uint trA, bool wrapX = false, bool wrapY = false ) : Bitmap	This is the extended C# port of the hq2x algorithm. The image is scaled to twice its size.
Scale2 ( uint sp, uint dp, int Xres, int Yres, uint trY = 48, uint trU = 7, uint trV = 6, uint trA, bool wrapX = false, bool wrapY = false ) : void	This is the extended C# port of the hq2x algorithm. The destination image must be exactly twice as large in both dimensions as the source image.
Scale3 ( Bitmap bitmap, uint trY = 48, uint trU = 7, uint trV = 6, uint trA, bool wrapX = false, bool wrapY = false ) : Bitmap	This is the extended C# port of the hq3x algorithm. The image is scaled to three times its size.
Scale3 ( uint sp, uint dp, int Xres, int Yres, uint trY = 48, uint trU = 7, uint trV = 6, uint trA, bool wrapX = false, bool wrapY = false ) : void	This is the extended C# port of the hq3x algorithm. The destination image must be exactly three times as large in both dimensions as the source image.
Scale4 ( Bitmap bitmap, uint trY = 48, uint trU = 7, uint trV = 6, uint trA, bool wrapX = false, bool wrapY = false ) : Bitmap	This is the extended C# port of the hq4x algorithm. The image is scaled to four times its size.
Scale4 ( uint sp, uint dp, int Xres, int Yres, uint trY = 48, uint trU = 7, uint trV = 6, uint trA, bool wrapX = false, bool wrapY = false ) : void	This is the extended C# port of the hq4x algorithm. The destination image must be exactly four times as large in both dimensions as the source image.
