    I need to develop simple image editor application.
    Need to edit image after loading (scale, zoom, scretch etc).
    How to display loaded image in application? Which control need to use for displaying images?

    If you're using Cocoa, look at NSImageView. You will either subclass that or make your own custom NSView. For scaling and zooming, look at NSAffineTransform. Stretching can be done by just drawing the image in a specific rectangle without scaling it proportionally.
