Hi there,

I'm having serious trouble using TrekBuddy on my Nokia 6303 classic with a map generated by OziMapTrans.

The map loads fine and I can scroll around, but after I have moved over around 6 to 10 tiles I always get caught in a loop of OutOfMemoryExceptions. Turning on the "forced GC" doesn't help, neither does any of the other options. The same map works perfect on a nokia E51 with s60 operating system.

My map has a tile size of 512x512 with 8bit color depth and sadly I'm not able to choose a smaller tile size with OziMapTrans for my source files, but I tried to reduce the number of tiles in the map down to 220 and it didn't make a change.

Honestly I don't expect the tile size to be the problem with 256k per tile, however I can't see any way to find out Sad

What I found out is that the problem occurs both with 2 and with 4 tiles currently on display.

I would really appreciate any help with this issue..

Did you try using other map sources which allow creation of smaller tiles?

I have uploaded two small test maps with 256x256 tiles, one tared, one uncompressed. Tile sizes go from 10 to 20 kBytes which is a fraction of your 256 k! Maybe you will give it a try with one of these maps.

Thanks for all the replies and especially to haddock for the test maps (btw my tiles are up to 150K, the 256K was just the theoretical upper boundary w/o compression).

I scrolled around both of the maps for several minutes and they work fine even without 1-tile-scroll so i guess the tile size is the issue..

@helge: I'm using the MagicMaps V2/3/4 importer to convert my MagicMaps 2 maps and it loads and converts them really well, but I can only select tile sizes down to 512 (see attached screenshots) - bug or feature? Wink

Greets,

Ah thank you Helge, I really didn't relate this setting to the conversion-dialog - it's not that intuitive, maybe a combobox with free input option for the tile size would be a nice addon?

Right now my 5-year old Notebook seems to take another 5 hours until the conversion of the Bavaria map is done and I'm gonna give feedback about the success later.

Regards,
Stefan

Good news and another thank you for your help guys. With the smaller tile sizes it now works like a clockwork!

Hi,

I settled to a tile size of 240x320=display resolution since that ensures a maximum of 4 tiles displayed at any time, which means faster loading when you scroll the map.

For my specific use case I used OziMapTrans since it was the only program that could read my map source.

Only thing I'm not happy with right now is the loading time for my huuuuge atlas...

HTH, Stefan

Have same phone and used to have same errors.
"1 tile" option helps, but is uncomfortable to use.

Then I've started using maps tiles in 16 colors PNG format. And all problems were solved. You don't need to use "1 tile" anymore.

NOTE: not 16 bits colors, but 16 colors PNG images

(Quantize option in GraphicsMagick/ImageMagic)
