android opencv 图像旋转90度,使用OpenCV转换图像( 旋转 90度)的简单方法？

以下是我的EmguCV ( OpenCV的C# 端口) 解决方案：public static Image Rotate90(this Image img)

where TColor : struct, IColor

where TDepth : new()

{

var rot = new Image(img.Height, img.Width);

CvInvoke.cvTranspose(img.Ptr, rot.Ptr);

rot._Flip(FLIP.HORIZONTAL);

return rot;

}

public static Image Rotate180(this Image img)

where TColor : struct, IColor

where TDepth : new()

{

var rot = img.CopyBlank();

rot = img.Flip(FLIP.VERTICAL);

rot._Flip(FLIP.HORIZONTAL);

return rot;

}

public static void _Rotate180(this Image img)

where TColor : struct, IColor

where TDepth : new()

{

img._Flip(FLIP.VERTICAL);

img._Flip(FLIP.HORIZONTAL);

}

public static Image Rotate270(this Image img)

where TColor : struct, IColor

where TDepth : new()

{

var rot = new Image(img.Height, img.Width);

CvInvoke.cvTranspose(img.Ptr, rot.Ptr);

rot._Flip(FLIP.VERTICAL);

return rot;

}

把它翻译成 C++ 应该不难。
