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 step 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. There is also disclosed a method of previewing a vector graphics image composed of a plurality of graphics elements comprising the steps of: parsing a vector graphics data file into individual graphics elements; selecting at least one graphics element; selecting and applying a scaling factor to a set of co-ordinate values defining the at least one selected graphics element; applying an inverse of the scaling factor to the set of co-ordinate values defining the at least one selected graphics element; displaying the graphics image including the graphics element having the scaling factor and inverse scaling factor applied thereto; and providing an indication of data file compression as a result of said scaling such that the effect of the scaling on image quality and data file size can be appreciated.
