FIELD: information technology. ^ SUBSTANCE: present invention relates to generation and use of files, containing mixed raster. The method of forming a mixed raster content (MRC) image involves stages for receiving commands for generation of an image file form an application program in form of a MRC image; generation of said MRC image by using a printer driver; generation of a selective layer; generation of a combined main/background layer; generation of lists of points for each region of the image, including the main layer, background layer and selective layer, where the lists include one or several of the following points: bounding region, type of graphic output and used colour; processing the said lists, where if the region of the image is text or line drawings, the region of the image is added to the selective layer, otherwise the region of the image is added to the main/background layer; and generation of a background layer and a main layer, each of which includes the corresponding point in the list of the background layer and list of the main layer, which does not intersect with the point in the list of the selective layer. ^ EFFECT: cutting on coding, decoding and composition time. ^ 12 cl, 20 dwg |
