3.3 Starting QGIS options: [--snapshot filename] emit snapshot of loaded datasets to given file [--lang language] use language for interface text [--project projectfile] load the given QGIS project [--extent xmin,ymin,xmax,ymax] set initial map extent [--help] this text FILES: Files specified on the command line can include rasters, vectors, and QGIS project files (.qgs): 1. Rasters - Supported formats include GeoTiff, DEM and others supported by GDAL 2. Vectors - Supported formats include ESRI Shapefiles and others supported by OGR and PostgreSQL layers using the PostGIS extension Tip 1 EXAMPLE USING COMMAND LINE ARGUMENTS You can start QGIS by specifying one or more data files on the command line. For example, assuming you are in your data directory, you could start QGIS with two shapefiles and a raster file set to load on startup using the following command: qgis ak_shade.tif alaska.shp majrivers.shp Command line option -snapshot This option allows you to create a snapshot in PNG format from the current view. This comes in handy when you have a lot of projects and want to generate snapshots from your data. Currently it generates a PNG-file with 800x600 pixels. A filename can be added after -snapshot. Command line option -lang Based on your locale QGIS, selects the correct localization. If you like to change your language, you can provide another language with this option. Command line option -project Starting QGIS with an existing project file is also possible. Just add the command line option - project followed by your project name and QGIS will open with all layers loaded described in the given file. Command line option -extent To start with a specific map extent use this option. You need to add the bounding box of your extent in the following order separated by a comma: --extent xmin,ymin,xmax,ymax QGIS 0.8 User Guide 7
3.4 QGIS GUI 3.4. QGIS GUI When QGIS starts, you are presented with the GUI as shown below (the numbers 1 through 6 in blue ovals refer to the six major areas of the interface as discussed below): Figure 1: Main window with spearfish sample data Note: Your window decorations (title bar, etc.) may appear different depending on your operating system and window manager. The QGIS GUI is divided into six areas: 1. Menu bar 2. Tool bar 3. Map legend QGIS 0.8 User Guide 8
