Hallo, I'm pretty new with both Python and C I have a C application that run a python script.The python script then uses some C functions written in the code that embedd the script itself. I want to pass array from the C code (where an API is giving pointer to data I want to plot in Python) and Python (a GUI).
What I've done so far is to allocate before calling the Pyhon script a PyArray with PyArray_SimpleNew. Since the data are unsigned char, the command is: my_second_array = (PyArrayObject *)PyArray_SimpleNew(2,dim,NPY_UBYTE); When I call the Python script,I sent my_second_array.On a timer, my_second_array is used as a parameter for a C written function: the idea is to assign the pointer of a frame to my_second_array.data. PyArrayObject *Pymatout_img=NULL; PyArg_ParseTuple(args, "O", &Pymatout_img);//Pymatout_img is the matrix that was created in C during the initialization with PyArray_SimpleNew Pymatout_img->data= cam_frame->data; The problem is that the compiler (I'm using visual C 2008) says that cannot convert *char to *unsigned char... Can someone explains me what i'm doing wrong? _______________________________________________ Cplusplus-sig mailing list Cplusplus-sig@python.org http://mail.python.org/mailman/listinfo/cplusplus-sig
