Perspectiva general del Diseñador de impresión¶

Ejemplo de sesión¶

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.

To demonstrate how to create a map please follow the next instructions.

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. Select the ^{Select/Move item} icon to select the map on the canvas and move it a bit.
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. Por último, puede guardar su diseño de impresión con el botón ^{Guardar proyecto}.

Puede añadir múltiples elementos al diseño de impresión. También es posible tener más de una vista de mapa o leyenda o barra de escala en el lienzo, en una o varias páginas. Cada elemento tiene sus propias propiedades y, en caso del mapa, su extensión. Si quiere borrar algún elemento del lienzo, puede hacerlo con Eliminar o la tecla Retroceso.

El Administrador de diseñadores¶

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:

EL Administrador de diseñadores

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

• show the selected composer(s): you can open multiple print composers in one-click
• 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.

Menus, tools and panels of the print composer¶

Al abrir el Diseñador de impresión le proporciona un lienzo en blanco que representa la superficie del papel al usar la opción de impresión . Inicialmente se encuentra botones del lado izquierdo del lienzo para añadir elementos al mapa del diseño; el lienzo del mapa actual de QGIS, etiquetas de texto, imágenes, leyendas, barras de escala, formas básicas, flechas, tablas de atributos y marcos HTML. En esta barra de herramientas también se encuentran los botones de barra de herramientas para navegar, acercar zum sobre un área y desplazar la vista y los botones de la barra de herramientas para seleccionar un elemento del diseñador del mapa y mover el contenido del elemento del mapa.

Figure_composer_overview shows la vista inicial del Diseño de impresión se añade antes que cualquier otro elemento.

Figure Composer Overview:

Diseñadores de impresión

Del lado derecho del lienzo encontrará dos paneles. El panel superior tiene las pestañas Elementos e Historia de la orden y el panel inferior tiene las pestañas Diseño, Propiedades del elemento y Generación de atlas.

• La pestaña Elementos proporciona una lista de todos los elementos del diseño añadidos al lienzo.

• La pestaña Historia de la orden muestra una historia de todos los cambios aplicados al diseño. Con hacer un clic, es posible deshacer y rehacer pasos de ida y de vuelta a un cierto estatus

• La pestaña Diseño le permite establecer el tamaño del papel, orientación, fondo de la página, número de páginas y calidad de impresión para el archivo de salida en dpi. Además, también se puede activar la casilla Imprimir como ráster. Esto significa que todos los elementos serán convertidos a ráster antes de imprimirse o guardarse como PostScript o PDF. En esta pestaña, también puede personalizar la configuración de la cuadrícula o guías inteligentes.

• 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.

• La pestaña Generación de atlas le permite habilitar la generación de un atlas del diseño actual y da acceso a sus parámetros.

In the bottom part of the Print Composer window, you can find a status bar with mouse position, current page number, a combo box to set the zoom level, the number of selected items if applicable and, in the case of atlas generation, the number of features.

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.

Table Composer 1: Print Composer Tools

Composition Tab¶

Tamaño y configuración de página¶

In the Composition tab, you can define the global settings of the current composition.

Figure Composition 1:

Composition settings in the Print Composer

You can choose one of the Presets formats for your paper sheet, or enter your custom width, height and units. You can also choose the page Orientation to use.

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 Botones de anulación de datos definidos.).

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).

Configuración de exportación¶

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.

Cuadrícula y guías¶

You can put some reference marks on your composition paper sheet to help you place some items. These marks can be:

• 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.
• or regular Grid.

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:

Snapping to grids in the Print Composer

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.

Command History Tab: Revert and Restore actions¶

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

• ^{Revert last change}
• ^{Restore last change}

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.
