8 Thoughts on “Map Grabber

    I’m sure you could make your MapGrabber even more functional than MapCapt – which a very usable CAPTURING interface, but doesn’t calibrate to the GPS.

    Any Thoughts??

    I’d like to use “Map Grabber” at work.
    Can I use it for business use?

    Can you please advise me?


    • Hi Sun
      I don see problem that you will use ‘Map Grabber’ at your work, if it in GNU General Public License, version 2.0 or later bounds. Also I would like to remind that there is not warranty on the application and I’m not responsible for the way that you are going to use my application by you.
      Also I gratefully appreciate a donation for the time that I put into development and supporting new projects.

  3. thank you very much

    I think Mapgrabber is brilliant and is exactly what I’ve been looking for.

    However, I notice that the magnifier doesn’t seen to be working. The box with OK and Cancel is there, but without the magnifier window.

    Is this a known issue, or is there something I need to do to activate it?
