"The easiest way to edit vector graphics is to import them into the GIMP, the standard raster graphics editor in free software. As you open an .SVG file in the GIMP, you can set the width and height of the file, as well as its resolution. If you plan to print the file, you will almost certainly want to increase the resolution, but, that done, you can then edit the file using the GIMP's complete collection of tools. The drawback is that the GIMP does not save to .SVG format, so you should only resort to it if you are willing to give up the advantages of the format."
