A method for displaying and navigating within a larger file containing graphic elements and for compressing a file containing text and graphic or image information

摘要

The invention relates to a display and navigation method for large data files containing graphic elements, in which the relevant data sections are displayed or presented on a monitor. In accordance with the invention, visual and controlled division of the display surface of the monitor takes place, preferably in a Cartesian co-ordinate grid with a centre field and surrounding edge fields. The data files necessary for the first display are then charged from a data base. After this, navigation directions and recharge orders are assigned to each of the edge fields of the grid, so that, when one of the edge fields activated, the data file content representing this field becomes the centre field, while the data file content which was hitherto not displayed, and was on the edge field or adjacent to the edge fields, can be reloaded from the main data file. The remaining, non-activated edge fields, which were adjacent to the hitherto centre field, are moved away from the selected navigation direction, or optionally removed from the monitor display. During navigation, reloading of the adjacent data file content takes place by means of the edge fields and the movement of the existing data files for the centre field, and by means of the edge fields which are not activated during navigation. This enables acceleration of the whole display process.
