Method for computing scale for tag insertion

A method for computing a scale factor to insert a first set of shapes into a second set of shapes to form a combined image, comprising:

• receiving the first set of shapes, including at least one shape, wherein the first set of shapes represents visual information to be placed inside the second set of shapes;
• receiving the second set of shapes, including at least one shape, wherein the second set of shapes defines the boundaries of a space for inserting the first set of shapes;
• using a processor to automatically convert the first set of shapes into a set of rectangles and the second set of shapes into a set of intervals;
• using the processor to automatically determine an initial scale factor and to generate the combined image by iteratively inserting the set of rectangles into the set of intervals and updating the scale factor in response to a residual area or an overflow area until a final scale factor is reached wherein all the rectangles in the set of rectangles have been inserted into the set of intervals and the residual area in the set of intervals is below a threshold;
• and
• storing the combined image in processor accessible memory.
