draw-priority – influence rendering order of two maps on a device
-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 Hi, one of our customers bought a propietary Garmin map (Topo Adria Pro) for his outdoor GPS reciever (GPSmap 62) and would like to have a secondary map on top of that map which shows some geometries (a boundary and a few POIs) we digitized from a paper map [1]. I successfully build a Garmin map using mkgmap which contains the boundary. If I load the map on the microSD card which already contains the propietary map, the map gets rendered but *below* the propietary map . I tried the following to get the additional map to be drawn on top: - - Rename the file by adding "aaa" at the beginning of the file name. - - Insert "aaa" at the beginning of the description (--description option of mkgmap). - - Insert "aaa" at the beginning of the family name (--family-name option ). - - Reduce number of --mapname option (I tried --mapname=10000000). - - Try different draw priorities using --draw-priority. I tried 999, 30 and 48 without any success. - - Build one gmapsupp.img containing both the Garmin Topo map and the additional map. java -jar mkgmap.jar --output-dir=../merged/ --gmapsupp ../input/garmin-topo.img ../output/additional.img Even if I change the order (additional.img before garmin-topo.img), nothing changes. Do you know at which location inside a gmapsupp.img file I can find the draw priority of the Garmin Topo map? If I know that draw priority, I can use a higher priority. Btw, I use mkgmap 3909.

Hi Michael, seems you have created your map with the default value of 25, maybe because you gave the option at the wrong place. Make sure to use --draw-priority=40 (or whatever you like) before specifying the input files, not after, like that: java -jar mkgmap.jar ... --draw-priority=40 mydata.osm Gerd ________________________________________ Von: mkgmap-dev <mkgmap-dev-bounces@lists.mkgmap.org.uk> im Auftrag von Michael Reichert <michael.reichert@geofabrik.de> Gesendet: Dienstag, 25.

Hi, I think that draw priority is limited to 31, I don't know what will happen if you set 40. You could try anyway. Michael, what you need is a transparent map. Instead of changing draw order, use --transparent option in mkgmap. This will draw your map over any other non-transparent. Without transparent option, your map would cover and hide any other map with lower draw order, like currently Topo Adria is hiding your map. -- Best regards, Andrzej

It is written to the file and gmaptool can read it correctly. I build a map with --transparent --draw-priority=34 and the output of gmaptool is:

Hi Michael, priority is saved on a byte, it can contain values up to 255. I have seen values like 60 on some Garmin's marine maps, but for a typical car or topo maps it is usually less than 31. Cgpsmapper manual limits this value to 31. While you can set higher priority, I would stay within common range, 25 is a good default. -- Best regards, Andrzej
