Converting .png to .meta
Hello,
I'm interesting in converting a directory structure of .png into .meta tiles so that i can serve them with mod_tile.
I came across some google results for convert_meta, but it seems that this is no longer built in the the current version of mod_tile.
Is there a replacement or alternative for convert_meta to accomplish what i'm after?
Thanks, Nick
Hi @nmaludy, convert_meta's source code is still part of mod_tile (see the src/convert_meta.c), however it doesn't seem to be compiled properly (since many many years). I would not know any alternative, but you can definitively try to make it run and if you succeed, it would be very nice to get a PR for it.
@xamanu I'm working on that now :) . I did get it to compile by copy/pasting some code from an older tag (0.4) into the conver_meta.c. Only hard part i have now is that my directory structure is z/x/y.png and i believe the newer "hash" structure is a different format. I need to figure out how to convert between the two.
Look for the function xyzo_to_meta somewhere.

Actually, a direct pointer: https://github.com/openstreetmap/mod_tile/blob/master/src/store_file_utils.c

I would like to know if this mystery has been solved, and if so, what the recipy is to get convert_meta running, since I would like to do the same thing. I'm prerendering a map layer by layer, but the result is not in the .meta format that the webserver uses, but in png. What to do?
