Abstract:
1. A method for supporting the automatic creation of computer-based drawings that are virtually free from graphics and text overwrites, comprising: a series of drawing plane bitmaps constructed by stroking graphics and text elements into an equivalent pixel set that represents committed drawing graphics and a separate equivalent pixel set that represents proposed drawing graphics; the use of said bitmaps to dynamically track the ongoing state of committed drawing graphics; the use of said bitmaps to compare proposed drawing graphics with already committed drawing graphics to confirm the availability of white space for the placement of proposed new graphics or to determine the degree of overwriting; and based on the availability of white space or the degree of overwriting, control variables and status variables are used to guide adjustments along a vector, or about a rotation point, as a means of moving proposed new graphics into either a location of white space or into a location with less overwriting.
