在Python中调用C++模块

一、一般调用流程

http://www.cnblogs.com/huangshujia/p/4394276.html

二、Python读取图像并传入C++函数，再从C++返回结果图像给Python

注意：1.Python传入数据的类型要与C++参数类型一致，类型参考下面链接

 ctypes基本数据类型映射表

参数类型预先设定好，或者在调用函数时再把参数转成相应的c_***类型。ctypes的类型对应如下:

ctypes type	C type	Python Type
c_char	char	1-character string
c_wchar	wchar_t	1-character unicode string
c_byte	char	int/long
c_ubyte	unsigned char	int/long
c_bool	bool	bool
c_short	short	int/long
c_ushort	unsigned short	int/long
c_int	int	int/long
c_uint	unsigned int	int/long
c_long	long	int/long
c_ulong	unsigned long	int/long
c_longlong	__int64 or longlong	int/long
c_ulonglong	unsigned __int64 or unsigned long long	int/long
c_float	float	float
c_double	double	float
c_longdouble	long double float	float
c_char_p	char *	string or None
c_wchar_p	wchar_t *	unicode or None
c_void_p	void *	int/long or None

2. 注意编译生成 so库的命令要正确，包括include和library的配置
