More on reading Image files.

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

My purpose in asking was to design an encryption program that would encrypt image files in the same way that I am encrypting text files by creating a kind of front end to my successful existing Ada-95 cipher.

I think it may be interesting to readers to tell you how far I think I have got with a solution to the problem that I posed that albeit outside of Ada may still be of interest to readers who are competent enough to consider a Java program as a pragma to my cipher in Ada-95.

You might let me know as feedback for the future if you think that is feasible i.e. a pragma program to an Ada program.

Without further ado here’s a link that you might like to look at.

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 questionnaire was beyond my ken.

I gave up after several attempts.

I’m putting the whole matter on the back burner until later now but it will be a Java solution eventually I think – not an Ada one. 

If  some kind reader manages to get past the questionnaire and  downloads anything perhaps they would tell me. 

Many thanks to everybody.

I think it is highly likely that some reader will be succesful in down loading the software - if so would you email me a copy at austin.obyrne@hotmail.com  

or send the correct answers you used to input to the questionaite so that I can do it also - many thanks.
