| − | Using Print Composer
| + | |
| − | </H2>
| + | |
| − | | + | |
| − | <P>
| + | |
| − | Before you start to work with the print composer, you need to load some
| + | |
| − | raster and vector layers in the QGIS map canvas and adapt their properties
| + | |
| − | to suite your own convinience. After everything is rendered and symbolized to
| + | |
| − | your liking you click the mActionFilePrintPrint Composer icon.
| + | |
| − | | + | |

| − | Opening the print composer provides you with a blank canvas to which you can
| + | |
| − | add the current QGIS map canvas, legend, scalebar, images and text. Figure
| + | |
| − | <A HREF="#fig:print_composer_blank">37</A> shows the initial view of the print composer
| + | |
| − | with an activated Snap to grid modus but before any elements are
| + | |
| − | added. The print composer provides two tabs:
| + | |
| − | | + | |
| − | <P>
| + | |
| − | | + | |
| − | <UL>
| + | |
| − | <LI>The General tab allows you to set paper size, orientation, the
| + | |
| − | print quality for the output file in dpi and to activate snapping to a grid
| + | |
| − | of a defined resolution. Please note, the Snap to grid feature
| + | |
| − | only works, if you define a grid resolution > 0. Furthermore you can also
| + | |
| − | activate the Print as raster checkbox. This means all elements
| + | |
| − | will be rastered before printing or saving as Postscript of PDF.
| + | |
| − | </LI>
| + | |
| − | <LI>The Item tab displays the properties for the selected map element.
| + | |
| − | Click the mActionSelectPanSelect/Move item
| + | |
| − | icon to select an element (e.g. legend, scalebar or label) on the canvas.
| + | |
| − | Then click the Item tab and customize the settings for the selected
| + | |
| − | element.
| + | |
| − | </LI>
| + | |
| − | </UL>
| + | |
| − | | + | |
| − | <P>
| + | |
| − | You can add multiple elements to the composer. It is also possible to have
| + | |
| − | more than one map view or legend or scalebar in the print composer canvas.
| + | |
| − | Each element has its own properties and in the case of the map, its own
| + | |
| − | extent.

| − | Adding a current QGIS map canvas to the Print Composer
| + | |
| − | </H3>
| + | |
| − | | + | |
| − | <P>
| + | |
| − | To add the QGIS map canvas, click on the mActionAddRasterLayerAdd new map
| + | |
| − | from QGIS map canvas button in the print composer toolbar and drag a
| + | |
| − | rectangle on the composer canvas with the left mouse button to add the map.
| + | |
| − | You will see an empty box with a <SPAN CLASS="textit">"Map will be printed here"</SPAN> message.
| + | |
| − | To display the current map, you can choose between three different modes in
| + | |
| − | the map Item tab:
| + | |
| − | | + | |
| − | <P>
| + | |
| − | | + | |
| − | <UL>
| + | |
| − | <LI>PreviewRectangle is the default setting. It only
| + | |
| − | displays an empty box with a message <SPAN CLASS="textit">"Map will be printed here"</SPAN>.
| + | |
| − | </LI>
| + | |
| − | <LI>PreviewCache renders the map in the current screen
| + | |
| − | resolution. If case you zoom in or out the composer window, the map is not
| + | |
| − | rendered again but the image will be scaled.
| + | |
| − | </LI>
| + | |
| − | <LI>PreviewRender means, that if you zoom in or out the
| + | |
| − | composer window, the map will be rendered again, but for space reasons, only
| + | |
| − | up to a maximum resolution.
| + | |

| − | You can resize the map later by clicking on the mActionSelectPanSelect/Move item
| + | |
| − | button, selecting the element, and dragging one of the blue handles in the corner of the map. With the
| + | |
| − | map selected, you can now adapt more properties in the map Item tab. Resize the map
| + | |
| − | item specifying the width and height or the scale. Define the map extend using Y and
| + | |
| − | X min/max values or clicking the set to map canvas extend button. Update the
| + | |
| − | map preview and select, whether to see a preview from cache or an empty rectangle with
| + | |
| − | a <SPAN CLASS="textit">"Map will be printed here"</SPAN> message. Define colors and outline width for the
| + | |
| − | element frame, set a background color and opacity for the map canvas. And you can also
| + | |
| − | select or unselect to display an element frame with the frame checkbox
| + | |
| − | (see Figure <A HREF="#fig:print_composer_map_item">38</A>). If you change the view on the QGIS | + | |
| − | map canvas by zooming or panning or changing vector or raster properties, you can
| + | |
| − | update the print composer view selecting the map element in the print composer and clicking
| + | |
