If you have such an image, then SVG has two options: either the BitMap is simply incorporated in the SVG-file, in which case enlargement has the same problems, or the BitMap is converted into geometric figures like Lines and Bezier curves. Inkscape has such a facility, but I don't know how well that works.
If you yourself create images by drawing straight lines and such into, say, a BufferedImage, then you might as well create a Path, that works similar to SVG and scales without blurring. See the API.
