    "This is a second post on the same matter (did a post on another ng two days


    I have a wallpaper of a movie and i want to make a cd cover out of it.
    I imagine a simple conversion of the square to circle shape.

    Can this be done in a easy way? This is my first contact with PhotoShop !

    'simple conversion of the square to circle shape'

    What does that mean? how can you possibly have a simple conversion of square
    to circle?

    If you are saying you want to take a circular section from a squre image?
    then that is simple, use the eliptical marquee tool with the shift key down,
    this gives you a circular selection, and whilst you still have the marquee
    tool selected you can move the circle anywhere on the image, then go to
    image crop, then inverse selection and delete, someone will no doubt know a
    better or just another way.

    Hello with thanks.

    I want to do (or hope at least) exactly what i describe. Firstly, have a
    scan of a dvd box cover, or find a photo on the Internet of any movie. This
    usually is square, or rectangular shaped.
    Secondly, change it to round without loosing picture info ? The border of
    the image can still remain rectangular, but the image itself will now be
    round. This way, i insert the photo on Nero Cover Designer and have more or
    less a cd cover with as many as possible info from the original picrure.

    I did what you proposed with the eliptical tool, but much info is lost this

    Is it clearer now ?

    Best regards

    Squares have more surface area than circles (of the same
    width/diameter), it's impossible to fit all the information in a square
    inside of a circle without losing the corners or morphing the image to
    fit so it is no longer square.

    ......unless you shrink your square to fit inside your circle entirely,
    but then you're losing a lot of cover space.

    Dupilcate your image layer, or double click it and make it layer 0 so
    it's editable (if it isn't already).

    Create a new layer above your image layer and fill with a solid color.

    Use the marquee tool (hold the shift key to constrain) to select the
    maximum size circle you can. Press CTRL-X to cut the selected circle
    from the color layer.

    Switch to your image layer, press CTRL-T. Hold down SHIFT and ALT to
    constrain and keep centered. Resize your image layer until it fits in
    your circle.

  6. Try looking at Filter>Polar coordinates

    As I said, you can't fit a square of the same width as the diameter of a
    circle into it without morphing the image or shrinking the square.

    Polar coordinates morphs the image, which as far as I could discern is
    not what the person wants to do.

    Hello again with many thanks.

    I understand that you "can not make an omelet without breaking an egg". I
    was hoping to break as few as possible ;).
    I imagined that i could "schrink" the four corner parts, leaving most of the
    center part intact.

    Anyway, I will try both suggestions (Filter and New Image Layer). At least
    it will be a good practice.

    Best regards
