In a method and system for display screen-aided generation of an electronic document from rasterized image data in an application computer, the image data are filed in at least one electronic storage. A first group of rasterized image data are provided stored page-by-page and a second group of rasterized overlay image data are provided in a relationship associated such that one page is associated with at least one overlay or one overlay is associated with at least one page. In a first display screen region, symbols of the first group are displayed per page in an ordered structure. In a second display screen region, image data of the first group are displayed. The document is generated an editor computer program loaded on the application computer from the rasterized image data and the rasterized overlay image data.
