Re: [mkgmap-dev] [Patch v1] improve LinePreparer to reduce img size

Hi Gerd, this is great improvement, thanks! I have tested your patch on a road map and get about 4% decrease of map size. I'm compiling topo map now, I think it is over 10% size reduction. I would like to suggest some optimizing of code. I think, you can get optimum bit length directly in procedure calcDeltas from LinePreparer. Just instead of only looking for min/max bit length, create full profile: number of legs vs bit length, so you can estimate full bit size like you have done it in your previous posts, without actually processing a line. I hope this makes sens, I don't know your code so well. -- Best regards, Andrzej
