Abstract: A digital image processing apparatus is provided which offers, for selection by an operator, at least one digital image data file for the purpose of further handling, e.g. printing. A file of this kind can be protected with a code which must first be input by the operator before the apparatus releases the file. If a number of files thus protected are selected and processed either together or in series by an operator, after the first file the apparatus first tries out for each subsequent file whether the code applicable for the preceding file is also valid for the new file. If so, the apparatus releases the file immediately, whereas otherwise it asks for a code again.

Abstract: A method of printing image information on a receiving material, two sides of which are provided with a binding portion for collecting a plurality of receiving materials into a booklet, the image information of at least two images being printed next to one another on the receiving material such that the images situated next to one another are printed with reading orientations rotated 180.degree. relative to one another and forming a right angle with the sides of the receiving material that are provided with the binding portion. To rotate the images, a fast method of rotating digital images is described which requires minimal memory space. Furthermore, the rotation method is particularly applicable to rotating a series of images and includes the capability of rotating each image in the series differently while utilizing minimal memory space and processor time.
