Thanks to everybody who has responded with t= he usual comp.lang.ada courtesy to my question regarding being able to read= the RGB colour ratios of pixels in an image file.

You might let me know as feedback for the future if you think tha= t is feasible i.e. a pragma program to an Ada program. Without further ado = here=92s a link that you might like to look at. http://www.developer.com/ja= va/other/article.php/3403921/Processing-Image-Pixels-using-Java-Getting-Sta= rted.htm According to the preface, this is exactly what I wanted and I was = delighted with it but it is a sponsored download and the stumbling block qu= estionnaire was beyond my ken. I gave up after several attempts. I=92m putt= ing the whole matter on the back burner until later now but it will be a Ja= va solution eventually I think =96 not an Ada one.

Many thanks to everybody. adacrypt I think it is highly likely that some reader will be succesful in down load= ing the software - if so would you email me a copy at austin.obyrne@hotmail= .com =20 or send the correct answers you used to input to the questionaite so that I= can do it also - many thanks. - adacrypt
