Revision history [back]

I have a module which receives a void pointer to a buffer. The original data type is uint16.

When I try putting the variable into a Mat, I get weird errors from Mat imBuff = cv::Mat(628, 314, frame, CV_16U); like missing '}' which isn't missing.

When I try various conversions using reinterpret_cast, I get cast from 'void*' to 'xxx' loses precision. For example, Mat imBuff = cv::Mat(628, 314, reinterpret_cast<uint16_t &gt;(frame),="" cv_16u);="" fives="" 'uint126_t'="" {aka="" short="" unsigned="" int}'="" loses="" precision<="" p="">

Any ideas on how to solve this?

Or, do I have to go back to the source file and change it there?

thanks Ralph
