A method for tailoring a master document to obtain a special document. The master document is made up of data objects and portions of the data objects. Included in the portions are pointers to corresponding data objects. The portions are windowed and displayed. Selection of a window will result in a view port being opened through the window into a corresponding data object. The data object can then be scrolled to obtain a desired portion to be included in the special document. As each desired portion is obtained, it is stored and becomes part of the special document.

Method for generating a document utilizing a plurality of windows associated with different data objects

A computer implemented method for generating a bitmap suitable for high-speed variable printing, comprising the steps of: (a) providing a page description language file, the page description language file defining at least one variable data area and at least one static data area; (b) interpreting the page description language file, and during the interpreting step: (i) generating a static bitmap of the static data area, (ii) identifying the variable data area, and (iii) responsive to the identification of the variable data area, not adding a bitmap of the variable data area to the static bitmap; and (c) saving the static bitmap, whereby the saved static bitmap is used repeatedly in the generation of a plurality of documents, each of which contain the static bitmap and a variable data bitmap.

Method of utilizing variable data fields with a page description language

This invention relates to high speed digital printing of pages each obtained by merging one or more page elements. A method is disclosed for merging page elements which are stored in a compressed format, the merging substantially in compressed domain to enable the implementation of the method to perform the merge rapidly, keeping up with a fast printing device. The merging occurs according to a page layout script which specifies the positions and printing order of selected page elements on each page. An apparatus for merging also is disclosed.

Compressed merging of raster images for high speed digital printing

A computer implemented method for generating a plurality of bitmaps suitable for high-speed printing includes the steps of: (a) providing a page description code specification that defines a data area and at least one graphical attribute associated with the data area, where the graphical attribute defines the appearance of at least a portion of data associated with the data area; (b) interpreting the page description code specification, and during this interpretation, identifying the data area defined by the page description code specification; (c) storing the graphical attribute associated with the data area upon identification of the data area in step (b); (d) retrieving an object bitmap; (e) applying the stored graphical attribute to the object bitmap to generate a bitmap suitable for high-speed printing; and (g) repeating steps (d) and (e) to create a plurality of bitmaps suitable for high-speed printing such that the stored graphical attribute is applied repeatedly in the generation of the plurality of the bitmaps suitable for high-speed printing.

Method and system for merging variable text and images into bitmaps defined by a page description language

A word processing system is provided with separate data structures in system memory (4). One of these, the internal image, contains the calculated graphics image and another the operator's alphanumeric character input. When displaying, the two images are merged together with the annotation overlay effectively overlaying the graphics overlay. In this way, if the operator erases something on the annotation overlay, the contents of the graphics overlay reappear. During the display of the calculated image and as the operator adds annotations to the display, overlaying conflicts between the graphics image and an alphanumeric character added by the operator are resolved in favor of the alphanumeric character. When an overlaying conflict does exist, the alphanumeric character is highlighted by video reversing to indicate that it is hiding a portion of the graphics image.

Independent image and annotation overlay with highlighting of overlay conflicts

A raster printer with sufficient flexibility so that text data and image data of any size and orientation can be placed at any position on a page. Input data has a succession of coded character data along with control data which specifies information concerning font selection and the placement of the characters on the page. Control circuits process the input data, one character at a time, and generate for each of the characters, data relating to the position of the character on the page, the size of the character and the address in storage of the graphic pattern for the character. The data is utilized by pattern move control logic to access the graphic pattern in the order the characters are to be printed and move the graphic data to a strip buffer. Data is read out of the strip buffer to energize imaging apparatus to print a page corresponding to the graphic pattern of the character data. An accumulator provides temporary storage for parts of the graphic pattern data and this data is logically ORed with later data so that a page of unlimited complexity can be printed.

Flexible text and image generator for a raster printer

A page (BASE PAGE) modification method in a printer subsystem of the partial page buffer composing type for generation of distinct copy groups (CG #1, CG #2, CG #3) or versions of a base page. A printer subsystem receives a packet containing a page of characters, coded overlays/elisions (OL #1, OL #2, S #1, S #2) and combining data from an external source. The packet is translated into a linked list of character placement representations for each of the doubly indexed coded characters within the page. Elisions (S #1, S #2) from the page are made by inhibiting the formation of a linked list segment for each character sequence within elision markers set out in the page. In contrast, coded character overlays are appended to the list as addenda. The list governs the placement of characters into a partial page buffer, whose contents are system accessible in row major order.
