  • Generating figures in a document formatter directly from a declarative tag
    Patent number: 4710885
    Abstract: A method for generating a graphical figure in a textual markup language used for document composition. A special tag in the mark-up language calls a procedure. The procedure consists of drawing a series of contiguous rectangular boxes, of very small extent in at least one dimension, so as to appear as continuous lines representing the figure. Text can be associated with the tag and included within the figure. The size of the figure then depends on the extent of the text.
