Generalități despre Compozitorul de Hărți¶

Sesiune de Probă¶

Before you start to work with the Print Composer, you need to load some raster or vector layers in the QGIS map canvas and adapt their properties to suit your own convenience. After everything is rendered and symbolized to your liking, click the ^{New Print Composer} icon in the toolbar or choose File ‣ New Print Composer. You will be prompted to choose a title for the new Composer.

Pentru a demonstra cum se poate crea o hartă folosiți următoarele instrucțiuni.

1. On the left side, select the ^{Add new map} toolbar button and draw a rectangle on the canvas holding down the left mouse button. Inside the drawn rectangle the QGIS map view to the canvas.
2. Select the ^{Add new scalebar} toolbar button and click with the left mouse button on the Print Composer canvas. A scalebar will be added to the canvas.
3. Select the ^{Add new legend} toolbar button and draw a rectangle on the canvas holding down the left mouse button. Inside the drawn rectangle the legend will be drawn.

4. Selectați pictograma ^{Select/Move item} pentru a selecta harta de pe canevas și pentru a o muta un pic.

5. While the map item is still selected you can also change the size of the map item. Click while holding down the left mouse button, in a white little rectangle in one of the corners of the map item and drag it to a new location to change it’s size.
6. Click the Item Properties tab on the left lower panel and find the setting for the orientation. Change the value of the setting Map orientation to ‘15.00° ‘. You should see the orientation of the map item change.
7. Now, you can print or export your print composition to image formats, PDF or to SVG with the export tools in Composer menu.

8. În cele din urmă, puteți salva compoziția cu ajutorul butonului ^{Salvare Proiect}.

You can add multiple elements to the Composer. It is also possible to have more than one map view or legend or scale bar in the Print Composer canvas, on one or several pages. Each element has its own properties and, in the case of the map, its own extent. If you want to remove any elements from the Composer canvas you can do that with the Delete or the Backspace key.

Managerul Compozițiilor¶

The Composer Manager is the main window to manage print composers in the project. It helps you add new print composer, duplicate an existing one, rename or delete it. To open the composer manager dialog, click on the ^{Composer Manager} button in the toolbar or choose Composer ‣ Composer Manager. It can also be reached from the main window of QGIS with Project ‣ Composer Manager.

Figure Composer Manager:

Managerul Compozitorului de Hărți

The composer manager lists in its upper part all the available print composers in the project. The bottom part shows tools that help to:

• a arăta compozito(arele) selectate: puteți deschide mai multe compozitoare de hărți printr-un singur clic

• duplicate the selected composer (available only if one print composer is selected): it creates a new composer using the selected composer as template. You’ll be prompted to choose a new title for the new composer
• rename the composer (also available only if one print composer is selected): You’ll be prompted to choose a new title for the composer. Note that you can also rename the composer by double-clicking on its title in the upper part
• remove the composer: the selected print composer(s) will be deleted from the project.

With the Composer Manager, it’s also possible to create new print composers as an empty composer or from a saved template. By default, QGIS will look for templates in user directory (~/.qgis2/composer_templates) or application’s one (ApplicationFolder/composer_templates). QGIS will retrieve all the available templates and propose them in the combobox. The selected template will be used to create a new composer when clicking Add button. You can also save composer templates in another folder. Choosing specific in the template list offers the ability to select such template and use it to create a new print composer.

Meniuri, instrumente și panouri ale compozitorului de hărți¶

Opening the Print Composer provides you with a blank canvas that represents the paper surface when using the print option. Initially you find buttons on the left beside the canvas to add map composer items: the current QGIS map canvas, text labels, images, legends, scale bars, basic shapes, arrows, attribute tables and HTML frames. In this toolbar you also find toolbar buttons to navigate, zoom in on an area and pan the view on the composer and toolbar buttons to select a map composer item and to move the contents of the map item.

Figure_composer_overview prezintă o vedere inițială a Compozitorului de Hărți, înainte de adăugarea oricăror elemente.

Figure Composer Overview:

Compozitorul de Hărți

On the right beside the canvas you find two panels. The upper panel holds the tabs Items and Command History and the lower panel holds the tabs Composition, Item properties and Atlas generation.

• Fila Elementelor oferă o listă a tuturor elementelor adăugate în canevasul hărții din compozitor.

• The Command history tab displays a history of all changes applied to the Print Composer layout. With a mouse click, it is possible to undo and redo layout steps back and forth to a certain status.
• The Composition tab allows you to set paper size, orientation, the page background, number of pages and print quality for the output file in dpi. Furthermore, you can also activate the Print as raster checkbox. This means all items will be converted to raster before printing or saving as PostScript or PDF. In this tab, you can also customize settings for grid and smart guides.
• The Item Properties tab displays the properties for the selected item. Click the ^{Select/Move item} icon to select an item (e.g., legend, scale bar or label) on the canvas. Then click the Item Properties tab and customize the settings for the selected item.

• Fila de Generare a atlasului vă permite să activați generarea unui atlas pentru Compozitorul curent, oferindu-vă acces la parametrii săi.

În partea de jos a ferestrei Compozitorului de Hărți, puteți găsi o bară de stare cu poziția mouse-ului, numărul curent al paginii, o casetă combinată pentru a seta nivelul de mărire, numărul de elemente selectate, dacă este cazul și, atunci când are loc generarea atlasului, numărul de entități.

In the upper part of the Print composer window, you can find menus and other toolbars. All Print Composer tools are available in menus and as icons in a toolbar. See a list of tools in table_composer_1.

The toolbars and the tabs can be switched off and on using the right mouse button over any toolbar or through View ‣ Toolbars or View ‣ Panels.

Fila Compoziției¶

Dimensiunea paginii și alte setări¶

În fila Compozițiilor, puteți defini setările globale ale compoziției dvs. curente

Figure Composition 1:

Setările Compozitorului de Hărți

Puteți alege unul dintre formatele de Presetare pentru pagina dvs, sau să introduceți propriile valori pentru lățime, înălțime și unități. Puteți folosi, de asemenea, pagina Orientare.

Composition can be divided into several pages. For instance, a first page can show a map canvas, and a second page can show the attribute table associated with a layer, while a third one shows an HTML frame linking to your organization website. Set the Number of pages to the desired value. you can also custom the Page Background with the color or the symbol you want.

The Page size options apply to all the pages in the composition. However, you can modify the values using the data defined override options (see Butoane de Suprascriere Definită de Date).

A custom page size can also be set, using the Resize page tool. This creates an unique page composition, resizes the page to fit the current contents of the composition (with optional margins).

Setări de export¶

You can define a resolution to use for all exported maps in Export resolution. This setting can however be overridden each time you are exporting a map. When checked, print as raster means all elements will be rasterized before printing or saving as PostScript or PDF.

While exporting to an image file format, you can choose to generate a world file by checking World file on and select a map item. The world file is created beside the exported map, has same name and contains information to easily georeference it.

Setările de Export din Compozitorul de Hărți

Grilă și de ghidaje¶

Se pot pune unele marcaje de referință pe foaia de hârtie a compoziției dvs., care vor ajuta la plasarea unor elemente. Aceste marcaje pot fi:

• simple lines (called Guides) put at the position you want. To do that, ensure that Show Rulers and Show Guides in View menu are checked. Then, click and drag from within the ruler to the paper sheet. A vertical or horizontal line is added to the paper and you can set its position following the coordinates displayed at the left bottom of the composer dialog.

• sau Grila obișnuită.

Whether grids or guides should be shown is set in View menu. There, you can also decide if they might be used to snap composer items. The Grid and guides section lets you customize grid settings like Grid spacing, Grid offset and Snap tolerance to your need. The tolerance is the maximum distance below which an item is snapped to a grid or a guide.

Figure Composition 3:

Setările grilei din Compozitorul de Hărți

In the Options ‣ Composer menu in QGIS main canvas, you can also set the spacing, offset and snap tolerance of the grid as much as its style and color. These options are applied by default to any new print composer.

Fila Istoricului de Comenzi: Acțiuni de Revenire și Restaurare¶

During the layout process, it is possible to revert and restore changes. This can be done with the revert and restore tools:

• ^{Anulează ultima modificare}

• ^{Restaurează ultima modificare}

This can also be done by mouse click within the Command history tab (see figure_composer_1). The History tab lists the last actions done within the composer. Just select the point you want to revert to and once you do new action all the actions done after the selected one will be removed.
