Convert FPX to XBM

If any fpx to xbm conversion is possible, it would be export between two somewhat uncommon bitmap graphics formats from  FPX (Kodak FlashPiX) to XBM (X Windows). It might be a little tricky to find graphics converter or editor that can be used to export or convert fpx to xbm directly, so you might actually need to use two tools for export of FPX and import of XBM format and some common graphics format (PNG/JPG or even BMP) as exchange format.
