For conversions involving SVG I've already posted my solution in this thread. For conversion between raster formats, I use convert from ImageMagick, or the netpbm tools. For conversions involving EPS or PDF I use ghostscript and associated tools. > How about screen capture, save as PNG? Most image manipulations have a screen-capture functionality, e.g. the GIMP.
