Hello, for our project (Geopard) which does indoor & outdoor mapping, we need zoom levels up to 24 or so. mod_tile's svn's render_config.h defines a constand #define MAX_ZOOM 18 (and also MIN_ZOOM) but this constant is used in only 2 or so files and the rest of max zoom values are hardcoded (just grep for 18 in the svn and you will find them)...
so I changed the code a little so that all harcoded max_zoom values are MAX_ZOOM instead... the executables are such that the maxZoom variable can be reset to something different than 18 (but that must be still lower than 18 (= harcoded max_zoom))... there's still minimum zoom values hardcoding (value is 0) in several files... I have no svn write access. Quite frankly, I know that I could look for all hardcoded values that should refer to defines in render_config.h though.. that's not a sufficient step... it would nice to just edit renderd.conf or override that with Apache mod_tile's mod_tile.conf options, instead of having to recompile the full mod_tile directory. I could implement code changes so that the executables effectively rely on only .conf files max, min zoom (and maybe other) parameters, and have a fallback .conf file for default values that can't be found and are removed from render_config.h such as mod_tile.conf.defaults and renderd.conf.defaults.... maybe there could be a compile option that enables or disables use render_config.h's #define'd constants / use of .conf files (with their .defaults counterpart when user forgets to provide vital options). I have to rush for now to provide a prototype, so will just the render_config.h #define MAX_ZOOM <nb greater than 18> 's way to recompile mod_tile for now.
