ceil function name collision.
Code:
cv::Size output_size
(gallerycols * 2 * its[0].cols(), ceil(4 / gallerycols) * 2 * its[0].rows());
Error 18 error C2668: 'ceil' : ambiguous call to overloaded function E:\Jacky\Downloads\voronoi\voronoi\test_voronoi.cpp 207 1 voronoi
I try to #include <cmath>
and use std::ceil to no avail
There are still function names clashing.
Thanks
Jack

Re: ceil function name collision.
Ceil() takes either a float or a double and returns either a float or a double. See http://msdn.microsoft.com/en-us/library/hh308218.aspx. Try
Code:
ceil((double)(4.0 / gallerycols)) * 2 * its[0].rows()
You may need to cast the result to an int.
