title: How to write floating point intensity into images? And then to read it back as floating point again?
body: <p>I'm currently working with <strong><em>Java</em></strong>, so if there's any function that I can work with Java itself then it'll be great.(Any other language is also fine as long as it works) I <em>cannot convert the floating point to int</em> because doing so I'll be losing the information that I had embedded in it. <strong><em>(My aim is to achieve Steganography so it'll lose its purpose</em></strong>). </p>
