Abstract:
The invention concerns a method for displaying a document on a display screen capable of being subjected to a scroll procedure, involving the following steps: providing the document with an amount of graphic memory to create a buffer memory of the visible part of the document and zones nearest to said visible part; calculating and cutting out into pixmaps said memory; relatively positioning said pixmaps with respect to the entire document and its visible part; filling up the content of the pixmaps, when the document is subjected to a display or scroll procedure, recopying the pixmap content in the display window; and repeating the relative positioning of the pixmaps with respect to the document.
