Thank you very much for your answers.
I tried GE2KAP and now I have great
charts from
google earth, but I couldn't manage to go from raster (scanned) charts to kap in a
single step. If I don't misunderstood something, I have to use the MapCal utility previously.
In this sense, the weatherfax
plugin worked fine (I got some weird colors when zooming out but I must re check what I'm, doing).
In my particular case, I'm using both
Linux (on boat) and Windows (at home), so the weatherfax plugin could be very handy to me.
Seems to me that a simple, portable, front-end for imgkap is something that deserves to be coded. Do you think it's something worth to do ?
