Summary: ctypes.Structure formal parameter dies given tuple
Initial Comment:
With a structure like:
class CvRect(ctypes.Structure):
_fields_ = [("x", ctypes.c_int),
("y", ctypes.c_int),
("width", ctypes.c_int),
("height", ctypes.c_int)]
and a foreign function like:
cvSetImageROI = _cxDLL.cvSetImageROI
cvSetImageROI.restype = None # void
cvSetImageROI.argtypes = [
ctypes.c_void_p, # IplImage* image
CvRect # CvRect rect
]
The call
cvSetImageROI(img, CvRect(1,2,3,4))
works fine but the mistaken call:
cvSetImageROI(img, (1,2,3,4))
Produces the "Send Error Report" dialog from Windows.
Other erroneous arguments produce a message about correct argument type but the
tuple triggers some other behavior.
