cGPSmapper DLL library

If you are developer and you want to include into your own program possibility of creating IMG maps, if you want to have *fast* and non memory consuming access to IMG files - you are at the right place.

First library - creating IMG files - free version available (distribution is allowed) with just a single banner window (with possibility of registration for 5 EUR only)

int main(int argc, char* argv[]) { //For the FREE version of DLL this is not required: if( cg_setSecurityValue("aaa","123446-123450-12345A-12345J-12345A1-1234G-1234F8-123440-123444-134211") != 1 ) cout<<"Error!"<<endl; //check what version of the library we have cout<<cg_getSecurityVersion()<<endl; unsigned char level[10]; level[0] = 22; level[1] = 20; level[2] = 19; level[3] = 18; level[4] = 17; cg_coordinate coords[20]; cout<<"Check version of cGPSmapper :"<<cg_getVersion(); //create IMG from mp file cg_init("a.img",2345,"test map",4,level); cg_readMP("marine_types_new.mp"); if( cg_buildMap() != _CG_OK ) cout<<cg_getError()<<endl; cg_done(); //create second IMG file cg_init("test.img",2345,"test map",4,level); cg_setOptional3(3,"M",1,24); coords[0].ns = 54.40919;coords[0].we = 18.63023; coords[1].ns = 54.40946;coords[1].we = 18.63126; coords[2].ns = 54.40998;coords[2].we = 18.63195; coords[3].ns = 54.41029;coords[3].we = 18.63202; coords[4].ns = 54.41165;coords[4].we = 18.63243; cg_addPolyline(4,0,0,3,"road",coords,5); coords[0].ns = 54.410;coords[0].we = 18.63185; cg_addPoint(2,0,0,1,"point",coords[0]); if( cg_buildMap() != _CG_OK ) cout<<cg_getError()<<endl; cg_done(); return 0; }

MapRead DLL library

If you want to access several IMG files at the same time - e.g. for fast render on the screen - then you should take a look into mapRead library

Very fast, with very limited memory consumption.
