PyrDown() 尺寸变小
PyrUp() 尺寸变大
public Image<TColor, TDepth> Resize( double scale, Inter interpolationType )
public Image<TColor, TDepth> Resize( int width, int height, Inter interpolationType )
public Image<TColor, TDepth> Resize( int width, int height, Inter interpolationType, bool preserveScale //如为true,图像比
