[mkgmap-dev] Optimizing MapSplitter

Wed Nov 12 08:44:31 GMT 2014

Hi Andrzej,

I tried different algos, but up to now I did not see any positive 
effect. I don't have a licence for cGPSmapper. 
If I got you right, you do this:
1) Create an img file with mkgmap
2) Convert it to *.mp (polish format) with GPSMapEdit
3) Compile that *.mp file with cGPSmapper

Finally you compare load those img files to your device and compare
redraw times. Please post a link to the two files and let me know 
what bbox you are testing.
