9.1 Using Map Composer Figure 18: Map Composer with map view, legend, scalebar, and text added To export the composer canvas as an SVG (Scalable Vector Graphic), click on the Export as SVG button. Note: Currently the SVG output is very basic. This is not a QGIS problem, but a problem of the underlaying Qt library. This will be sorted out in future versions. QGIS 0.8 User Guide 65
10. Using Plugins 10.1. An Introduction to Using Plugins QGIS has been designed with a plugin architecture. This allows new features/functions to be added to the application. Many of the features in QGIS are actually implemented as plugins. There are two types of plugins in QGIS: core and user-contributed. A core plugin is maintained by the QGIS development team and is part of every QGIS distribution. A user-contributed plugin is an external plugin that is maintained by the individual author. The QGIS SVN website (http://svn.qgis.org) serves some user contributed plugins. 10.1.1. Finding and Installing a Plugin When you install QGIS, all of the core plugins are included (see chapter 10.1.4). Typically user-contributed plugins are distributed in source form and require compiling. For instructions on building and installing a user-contributed plugin, see the documentation included with the plugin. 10.1.2. Managing Plugins Managing plugins consists of loading or unloading them from QGIS. Loaded plugins are "remembered" when you exit the application and restored the next time you run QGIS. To manage plugins, open the Plugin Manager from the Tools menu. The Plugin Manager displays all the available plugins and their status (loaded or unloaded). Figure 19 shows the Plugin Manager dialog. Typically all QGIS plugins are installed in the same location. This location is shown in the Plugin Directory text field. You can tell QGIS to load plugins from another location by specifying a different directory. Tip 31 CRASHING PLUGINS If you find that QGIS crashes on startup, a plugin may be at fault. You can stop all plugins from loading by editing your stored settings file (see 3.8 for location). Locate the plugins settings and change all the plugin values to false to prevent them from loading. For example, to prevent the Delimited text plugin from loading, the entry in $HOME/.config/QuantumGIS/qgis.conf on Linux should look like this:Add Delimited Text Layer=false.Do this for each plugin in the [Plugins] section. You can then start QGIS and add the plugins one at a time from the Plugin Manger to determine which is causing the problem. QGIS 0.8 User Guide 66
