Tutorial – DPI Explained

Header Image

I’ve been working on improved learning materials for Codename One. One of the problems with videos is that I can sometimes unintentionally drag an idea that can be explained with a single image. DPI is one of those ideas, I’m assuming most of you already understand it but even if you do, I think this graphic helps put things in perspective.

    I think you need to step back and re-evaluate. That picture explains nothing. And I’m a professional programmer well versed in dpi and scaling issues. That’s just a lot of figures that only mean anything if you already understand it.

    Thanks for the feedback. How would you improve that graphic?
    The target audience for this graphic are programmers who have no experience in mobile. I just want to help visualize the density issue, not the solutions which would require a different graphic.
