1. A method of modifying the geometric orientation of a digital image in an image acquisition apparatus adapted to acquire an image from at least one of a plurality of different orientations and to store the image in a form of a compressed file, said method comprising the steps of:

  • acquiring the image in a chosen orientation;

    identifying the chosen orientation;

    converting the image into a digital image;

    spectral transforming the digital image;

    determining a geometric transformation to be applied to the image acquired as a function of the chosen orientation;

    applying the determined geometric transformation to symbols associated with spectral coefficients issuing in said in spectral transforming step;

    recording in the compressed file two indicators representing a normal or reversed order of the symbols respectively in two directions of the digital image; and

    coding the digital image in the compressed file.
