Vector graphics - online puzzles

Vector graphics use 2D point located polygons to represent images in computer graphics. Each of these points has a definite position on the x- and y-axes of the work plane and determines the direction of the path; further, each path may have properties, including such values as stroke color, shape, curve, thickness, and fill. Vector graphics are commonly found today in the SVG, EPS and PDF graphic file formats and are completely different from the more common raster graphics file formats of JPEG, PNG and MPEG4.
