Re: Read Image's RGB co-ordinates Nuri Ismail10-Sep-09 2:29 Nuri Ismail 10-Sep-09 2:29  Just in addition to CPallini's post. If you decide to use CImage class you will notice that the GetPixel and SetPixel methods are slow. So if you need a fast pixel access you can use this[^] class with combination of CImage class. Using CxImage[^] library could also be an option.
