how do a pass a pointer to a C datatype to my python extension type
constructor? I have the following in my code:
#### in a cdef extern from .h block ######
struct _IplImage:
<filler>
ctypedef _IplImage IplImage
###### extension type declaration #######
cdef class PyIplImage:
cdef IplImage* img
cdef readonly int width, height
def __cinit__(self, IplImage* imgptr):
self.img = imgptr
self.width = self.img[0].width
self.height = self.img[0].height
###### test functions #################
cdef IplImage* load(char* filename):
cdef IplImage* img = cvLoadImage(filename, 1)
return img
def testload(filename):
cdef IplImage* img = load(filename)
pyimg = PyIplImage(img)
return pyimg
Cython compilation errs with "Cannot convert IplImage* to python object"
