The goal of this package is the simplest possible provision of
map images (OpenStreetMap, Google Maps and Google Street View 
are supported). In the simplest case, the specification of an
address is sufficient. The package loads the map using the
\write18 feature, which you must activate to use this package.
The image will be downloaded by an external Lua script. You can 
use this script also from the command line.

License: LPPL

Changes in v1.3:

- added support for Google Street View

  * new options heading, pitch, fov

- added more examples to the documentation


  INSTALL
===========

First of all, install the package with the package manager of
your TeX distribution, if possible! A getmap package is
available for TeXLive2014+ and MiKTeX!

Manual installation:

download getmap.dtx and makefile (Linux) or install.bat (Windows)

* Linux

  simply run  make  to extract the files and to create the
  documentation. Run  sudo make install  to copy the files 
  into $TEXMFLOCAL
  
  Moreover, there are the following usefull make targets:
  
  uninstall  deletes the package in $TEXMFOCAL  
  package    only extracts the files  
  clean      cleans all aux files  
  cleanall   cleans all files except the downloaded files

* Windows

  In MiKTeX scripts like getmapdl.lua must be registered.
  This can not be done manually! Please use the package
  manager to install getmap.
  
  For TeXLive simply run install.bat! It assumes that you
  use a standard installation of TeXLive2014. Otherwise you 
  must adjust the variables in the first lines of install.bat!

% \Headline{Abstract}
% \begin{abstract}
% The goal of this package is the simplest possible provision of
% map images (OpenStreetMap, Google Maps and Google Street View 
% are supported). In the simplest case, the specification of an
% address is sufficient. The package loads the map using the
% \cmd\write18 feature, which you must activate to use this package.
% The image will be downloaded by an external Lua script. You can 
% use this script also from the command line.
% \end{abstract}
% \vfill
% \renewcommand*{\abstractname}{Acknowledgment}
% \begin{abstract}
% I want to thank Norbert Preining, who did most of the recoding of \texttt{osmimage}
% (\texttt{Bash} $\rightarrow$ \texttt{Lua}). Moreover many thanks to Taco Hoekwater,
% Reinhard Kotucha and Heiko Oberdiek for their valuable contributions.
% \end{abstract}
% \clearpage
% \section{Options}
% The following options can be used as package options with global scope,
% as well as options for the \cmd\getmap\ command with local scope!
% \subsection[\texttt{mode}]{\texttt{mode (\underline{osm}\textbar{}gm\textbar{}gsv})}
% This option sets the mode, that is the source of the images. OpenStreetMap, Google Maps or Google Street View!
% \subsection[\texttt{key}]{\texttt{key (\underline{Fmjtd\textbar{}luur20u22d,75=o5-9aylh6}})}
% In \texttt{osm} mode, the download script requires a key in order to use the service of MapQuest.
% By default, it uses a key, which is registered for \package{getmap}.
% But you can register and use your own key with this option.
% The default key is stored in \texttt{getmap.cfg}. You can copy this file to your local \TeX\ tree
% and store your own key there\footnote{Mapquest will deliver an url-encoded key, which must
% be decoded to ASCII, e.g. by \href{http://urldecode.org/}{Url decode}}!
% This file will be found after running \texttt{texhash}!
% \subsection[\texttt{scale}]{\texttt{scale (\underline{3385} (osm), \underline{1} (gm)})}
% \texttt{osm}: This option allows you to specify a display scale for the map image in the range of
% 1692 -- 221871572. You will not necessarily see a difference between 5000 and 5500.
% A scale value of 3385 corresponds to a zoom level of 17.
%
% \texttt{gm}: For the free version of Google Maps the image size is limited to 640x640.
% You can set \texttt{scale} to a value of 2, to get exactly the same map in doubled size in pixels.
% \subsection[\texttt{zoom}]{\texttt{zoom}}
% This option allows you to specify a zoom level in the range of 1 -- 18
% ( osm - this option overwrites a possibly given scale) or 0 -- 21 (gm).
% \subsection[\texttt{xsize}]{\texttt{xsize (\underline{600})}}
% This option specifies the width of the map in pixels.
% If \marginpar{\footnotesize\fbox{\parbox{3cm}{\raggedright{}changed default value to \texttt{600} in version 1.2!}}}
% you only want to slightly increase or decrease the map extract,
% you should adjust the size of the map. You still have full control over the size of
% the map in the document with the options of \cmd\includegraphics. (max: 3840 (osm) or 640 (gm))
% \subsection[\texttt{ysize}]{\texttt{ysize (\underline{400})}}
% This option specifies the height of the map in pixels. max: 3840 (osm) or 640 (gm))
% \subsection[\texttt{file}]{\texttt{file (\underline{getmap})}}
% This \marginpar{\footnotesize\fbox{\parbox{3cm}{\raggedright{}changed default value to \texttt{getmap} in version 1.2!}}}
% option allows you to specify the name of the image (without extension).
% \subsection[\texttt{imagetype}]{\texttt{imagetype (\underline{png})}}
% This option allows you to specify the type of the image.
%
% \texttt{osm}: \texttt{\underline{png}\textbar{}jpeg\textbar{}jpg\textbar{}gif}
%
% \texttt{gm}: \texttt{\underline{png}\textbar{}png8\textbar{}png32\textbar{}gif\textbar{}jpg} (progressive)\texttt{\textbar{}jpg-baseline} (flat)
% \subsection[\texttt{type}]{\texttt{type (\underline{map} (osm)\textbar{}\underline{roadmap} (gm))}}
% This option specifies the type of the map.
%
% \texttt{osm}: \texttt{\underline{map}\textbar{}sat\textbar{}hyb} \quad\quad\ It seems as if there would be only a few regions of Mother Earth,
% for which satellite and hybrid images are available.
%
% \texttt{gm}: \texttt{\underline{roadmap}\textbar{}satellite\textbar{}hybrid\textbar{}terrain}
% \subsection[\texttt{color}]{\texttt{color (\underline{yellow\_1}) (osm)\textbar{}\underline{blue} (gm))}}
% This option specifies the color of the marker. Possible colors:
%
% \texttt{osm} \href{http://open.mapquestapi.com/staticmap/icons.html}{http://open.mapquestapi.com/staticmap/icons.html}
%
% \texttt{gm}: black, brown, green, purple, yellow, blue, gray, orange, red, white or in hex format \texttt{0x3399FF}
% \subsection[\texttt{number}]{\texttt{number (\underline{1})}}
% This option specifies the number of the marker.
% \subsection[\texttt{heading}]{\texttt{heading (\underline{0})}}
% This option specifies the heading (direction) in degrees in the range of 0 -- 360 (gsv mode). (0: north, 90: east, ...)
% \subsection[\texttt{pitch}]{\texttt{pitch (\underline{0})}}
% This option specifies the pitch (angle) of the camera view in degrees in the range of -90 -- 90 (gsv mode).
% \subsection[\texttt{fov}]{\texttt{fov (\underline{90})}}
% This option specifies the field of horizontal view (kind of zoom) in degrees in the range of 0 -- 120 (gsv mode).
% \subsection[\texttt{inputencoding}]{\texttt{inputencoding}}
% This option specifies the input encoding of your file.
% The download script requires the strings encoded in utf8.
% For the safe conversion the input encoding of the file is required.
% Normally, you don't have to specify an encoding.
% The package tries to evaluate the encoding given to \package{inputenc} or assumes utf8.
% Usually that should work.
% \subsection[\texttt{overwrite}]{\texttt{overwrite (\underline{false}\textbar{}true)}}
% With this option, you can specify whether the image should be downloaded in any case.
% By default, the option is set to \texttt{false} in order to save bandwidth and compilation time.
% Nevertheless a check is performed on the existence of the image and the
% image will be downloaded, if it is not present.
% In the case of \texttt{true}, the image will be downloaded anyway!
% BTW, \texttt{overwrite} is equivalent to \texttt{overwrite=true}.
% \section{Command(s)}
% \subsection{\cmd\getmap}
% With the \cmd\getmap\ command\margcs{\cmd\getmap\oarg{options}\marg{address}} you can download
% a map, if you enable \cmd\write18 (TeXLive: \texttt{-shell-escape}, MiKTeX: \texttt{-{}-enable-write18}).
% This is only necessary if you actually download an image.
% You can use the options described above to specify the properties of the downloaded image.
% After executing the command, the image is available in the current working directory!
%
% In the simplest case, you only need an address, a POI or geographic coordinates
% (\texttt{latitude,longitude}) to download the map. \marg{address} must be fully expanded and must not contain macros!
% By default, the image is saved under the name \texttt{getmap.png}!
% If you need only one map (e.g. the office of Dante e.V.) in your document, it can be as simple as:
