When my map expands, I see remnants of another zoom level
|
|
---------------------------------------------------------
|
|
|
|
When your map expands ("Your map seems to have expanded beyond its previous
|
|
bounds") you may see tiles at a zoom level that shouldn't be there, usually
|
|
around the borders. This is probably not a bug, but is typically caused by
|
|
copying the map tiles from their render destination to another location (such as
|
|
a web server).
|
|
|
|
When you're copying the rendered map, you need to be sure files that *don't*
|
|
exist in the source are *deleted* in the destination.
|
|
|
|
Explanation: When Overviewer re-arranges tiles to make room for another zoom
|
|
level, it moves some tiles tiles at a particular zoom level and places them at a
|
|
higher zoom level. The tiles that used to be at that zoom level should no longer
|
|
exist there, but if you're copying tiles, there is no mechanism to *delete*
|
|
those files at the copy destination.
|
|
|
|
If that explanation doesn't make full sense, then just know that you must do one
|
|
of the following:
|
|
|
|
* Render the tiles directly to the destination
|
|
|
|
* Copy the tiles from the render destination in a way that deletes extra files,
|
|
such as using ``rsync`` with ``--delete``
|
|
|
|
* Erase and re-copy the files at the final destination when the map expands.
|
|
Map expansions double the width and height of the map, so you will eventually
|
|
hit a map size that is unlikely to need another level.
|
|
|
|
The full map doesn't display even when fully zoomed out!
|
|
--------------------------------------------------------
|
|
|
|
Are you using the :option:`-z` or :option:`--zoom <-z>` option on your
|
|
commandline or in settings.py? If so, try removing it, or increasing the value
|
|
you set. It's quite likely you don't need it at all. See the documentation for
|
|
the :option:`zoom <-z>` option.
|
|
|
|
You've added a few feature or changed textures, but it's not showing up on my map!
|
|
----------------------------------------------------------------------------------
|
|
|
|
Some new features will only show up in newly-rendered areas. Use the
|
|
:option:`--forcerender` option to update the entire map. If you have a really
|
|
large map and don't want to re-render everything, take a look at
|
|
the :option:`--stochastic-render` option.

How do I use this on CentOS 5?
|
|
------------------------------
|
|
|
|
CentOS 5 comes with Python 2.4, but the Overviewer needs 2.6 or higher. See the
|
|
special instructions at :ref:`centos`
|
|
|
|
The background color of the map is black, and I don't like it!
|
|
--------------------------------------------------------------
|
|
|
|
You can change this by using the :option:`--bg-color` command line option, or
|
|
``bg_color`` in settings.py. See the :doc:`options` page for more details.
|
|
|
|
I downloaded the Windows version but when I double-click it, the window closes real fast.
|
|
-----------------------------------------------------------------------------------------
|
|
|
|
The Overviewer is a command line program and must be run from a command line. It
|
|
is necessary to become at least a little familiar with a command line to run The
|
|
Overviewer (if you have no interest in this, perhaps this isn't the mapping
|
|
program for you).
|
|
|
|
Unfortunately, A full tutorial of the Windows command line is out of scope for this
|
|
documentation; consult the almighty Google for tutorials and information on
|
|
the Windows command line. (If you would like to contribute a short tutorial to
|
|
these docs, please do!)
|
|
|
|
Batch files are another easy way to run the Overviewer without messing with
|
|
command lines, but information on how to do this has also not been written.
|
|
|
|
On a related note, we also welcome contributions for a graphical interface for
|
|
the Overviewer.
