History

Blake Thompson badb0c9a97 This is a complete removal of code that utilizes image_32 in the library. It is a sweeping change that does some of the following: * Changes all agg_renderers to use a image_data_any variant (only image_data_rgba8 is implemented currently) * Changes the marker and marker_cache to use image_data_any images * Changes the symbolizers so that they must be aware of the source data type they are attempting to render and the render type that is expected to be rendered into. * Moves many utilities into image_utils, that were previously in image_32. The kicker is that this still isn't working perfectly yet, but I am commiting so I don't have tears in case everything is lost on my computer. Ref #2633		2015-01-20 18:30:10 -06:00

README.md

rundemo.cpp

This directory contains a simple c++ program demonstrating the Mapnik C++ API. It mimics the python 'rundemo.py' example with a couple exceptions.

If building on unix you can have this program automatically build by configuring Mapnik like:

./configure DEMO=True

However, this example code also should be able to be built standalone.

The following notes describe how to do that on various operating systems.

Depends

Mapnik library development headers
mapnik-config on unix and mapnik-config.bat on windows

Unix

On OS X and Linux you also need make.

Windows

On windows, additional dependencies to build are:

MSVS 2010 with C++ compiler
Python 2.x
gyp: https://code.google.com/p/gyp | https://github.com/springmeyer/hello-gyp

mapnik-config.bat should come with your Mapnik installation.

First confirm it is on your path:

mapnik-config # should give usage

To install gyp, which is pure python do:

svn checkout http://gyp.googlecode.com/svn/trunk/ gyp
cd gyp
python setup.py install

If you do not have svn installed you can grab gyp from:

https://github.com/TooTallNate/node-gyp/archive/master.zip
# unzip and extract the 'gyp' subfolder then do
cd gyp
python setup.py install

Building the demo

Unix

Simply type:

make

Then to run do:

./rundemo mapnik-config --prefix

On OS X you can also create an xcode project:

gyp rundemo.gyp --depth=. -f xcode --generator-output=./build/
xcodebuild -project ./build/rundemo.xcodeproj
./build/out/Release/rundemo `mapnik-config --prefix`

Windows

First you need to build the visual studio solution with gyp:

C:\Python27\python.exe c:\Python27\Scripts\gyp rundemo.gyp --depth=. -f msvs -G msvs_version=2010

Then you can compile with msbuild:

msbuild rundemo.sln /p:Configuration="Release" /p:Platform=Win32

Then run it!

for /f %i in ('mapnik-config --prefix') do set MAPNIK_PREFIX=%i
Release\rundemo.exe %MAPNIK_PREFIX%
