Abstract:
1. A method of manipulating a vector graphics data file representative of at least one graphics element defined by a set of co-ordinate values in a graphics image, the method comprising the steps of scaling down the at least one graphics element by applying a scaling factor to the set of co-ordinate values defining the at least one graphics element, wherein each of the co-ordinate values is represented by a bit sequence and the step of applying the scaling factor comprises the step of removing at least the least significant bit from the bit sequences representing the co-ordinate values, and wherein the scaling factor comprises a combined scaling factor having a value which lies between 2 n and 2 n+1 , where n and n+1 are integer values representing the number of bits to be removed from the bit sequence, the number of bits being dependent on the co-ordinate value being scaled; and displaying the at least one graphics element.
