Victor The function Import returns a graphics object - which includes the RGB (or other colour function) coordinates of each pixel. A little experimentation will show you how to extract the numbers from the rest of the graphics info. I suggest that you start with very small images until you are confident in handling the raw data. I imagine you could then export the data to an Excel spreadsheet but I cannot for the life of me understand why, having imported it into Mathematica in the first place, you would want to do so. Hope this helps with the first step at least Regards Mark Westwood victor carvalho wrote: > > hello, > > I am trying to obtain the raw information of a picture BMP (array of > numbers) and import it to excel spreadsheet to calculate some things. > > Do you guys have any idea how can I do that? > > thanks in advance, > > Victor
