Road, rail & town extractor
« on: September 09, 2018, 10:59:50 AM »

When reworking the street and rail net of the black sea map i found it usefully and also necessary to extract the roads and rails and also the towns and villages from the map_t.

For this i wrote a little tool, that creates from a map_t

a map_t.tga without roads and rails ("map_tNoRoadsNoRails.tga")
a TGA with white background with roads and rails alone ("map_t_RoadsAndRails.tga")
and a TGA with white background with the towns and villages alone ("map_t_Towns(Colours).tga).



The road and town files used as layers and after adding transpareny joining them with the "add colours" feature of gimp to the pure map_t are usefull to create a new complete map_t and also the ed_m files.

Before extracting the towns and villages there is a prompt:"Type in colours of towns and villages separated with commas, then press Enter:". Type in then the colours of towns and villages according to the load.ini, for example: "14,15,17,18,19". The tool then will create a "map_t_Towns1415171819.tga".

Of course you also can extract any other colour of a map_t.

The tool also shows the length of the roads and rails. With the BlackSea map i found

4962 km of country roads
933 km of highways
and 1313 km of railroads.

You may download the tool here:

Usage: Throw the tool and the map_t.tga into the same folder. Run the tool. Type in the colours of the map_t to extract towns and villages (or other colours), separated with commas.

Seems promisimg, I shall try it.
Formerly, I used a program "Decomp", but it failed to work properly om some larger maps.

I don't think there will be a problem with bigger maps here, also i did not tested this. If your rig can load a map_t, the tool should load it also.

I forgot to mention: I also used the road.tga as a layer to the map_h to paint the roads and rails in the valleys and to delete the old roads. Also it is quite impossible to meet the lowest parts of a valley, this nevertheless helps to paint roads and rails near to the place at least where they should be. I also found that its possible to delete roads and rails within the fmb: Selecting "Rail" or the type of road in the objects menue, pointing with the mouse directly over the road/rail and pressing "Delete" removes them. Don't know if this is kown ;-).

There was a typo in that program. But this affected only crossing roads/rails, so wrong calculation of the roads/rails lenght was less than 2% with the BlackSea map. I replaced the first download with a fixed version meanwhile.
