Registro de cambios para QGIS 2.4

Change log for the next release of QGIS 2.4.0. The emphasis on this release has been very much on polish and performance - we have added many new features, tweaks and enhancements to make the user interface more consistent and professional looking (and hopefully easier to use). The composer (used for creating print ready maps) has had a lot of work done to it to make it a more viable platform for creating great cartographic outputs.

Siempre que se agregan nuevas características a un software se introduce la posibilidad de nuevos fallos - si encuentra algún problema con este lanzamiento, por favor registre un boleto en el Rastreador de Fallos QGIS.

Nos gustaría agradecer a los desarrolladores, documentadores, probadores y a las muchas personas que ofrecen su tiempo y esfuerzo voluntario (o financian a personas que lo hacen).

General

Feature: Generate band name with NetCDF EXTRA_DIM

The NetCDF provided extra dimensional information. This information provides metadata on each band. These metadata can be used to explain the name of each band. For example, the bands of a NetCDF file represents the temperature at a given depth. For the user, it is easier to select a band with depth information, rather than only the band number.

Característica: Aplicando escala y desplazamiento a datos ráster

In some raster datasources, data are stored as interger with a scale and an offset in the metadata. The scale and offset can be used to get the right data. QGIS applies its to raster data to provider to users right information for legend, histogram and identify.

Característica: Barra de cálculo rápido de campo en tabla de atributo

Tenemos una grandiosa nueva característica para aquellos trabajando con campos calculados en tablas de atributo vector. La nueva barra de cálculo rápido le permite rápidamente y fácilmente actualizar los valores en una columna en la tabla de atributos.

Característica: Modos de previsualización de color en el diseñador y tela del mapa

A really innovative feature that has been added to 2.4 is support for grayscale and colour blindness previews. This allows you to visualise how people with colour blindness will perceive your cartography and map layout, or how your map will look if it’s printed in grayscale. You can read more about this new feature here.

Característica: archivos Capa QLR QGIS

Added support for QGIS Layer Definition files or simply QLR (see http://nathanw.net/2014/03/12/qgis-qlr/). QLR file is a file that points to the data, contains all the styling, and other information. You can then just add this file and it will do all the other magic for you. QLR makes it easy to add same layer to multiple map documents, inheriting all of the properties which have been set and works with any layer supported in QGIS, expect special plugin layers.

Característica: Nuevas funciones de expresión

Tenemos algunas funciones nuevas disponibles en el contructor de expresiones.

  • caja delimitadora (bordes)
  • bounding box width & height (bounds_width/bounds_height)
  • min/max x/y coordinates (xmin/xmax/ymin/ymax)
  • new wordwrap function that returns a string wrapped to a maximum/minimum number of characters

Característica: Copia, pega y arrastra y larga colores

You can now copy, paste, drag and drop colours between any colour input widget in QGIS. See this article for more information on how this new feature works. Hex color codes and rgb strings can also be pasted on to colour buttons to allow importing colours from outside of QGIS.

image6

Característica: Reproducción multipropósito

This is one feature we simply cannot do justice to with a screenshot - QGIS now supports multi-threaded rendering! What this means is that when drawing the map, QGIS will split the drawing work between all of the cores in your CPU, making the process more efficient and responsive. By responsive we mean that you no longer need to wait for the map view to update before you can pan or zoom again. Also the map display updates incrementally allowing you to see if the map is positioned correctly early on in the drawing process. Take a look at this article for a more detailed overview of the multi-threaded rendering system. You will find some options in the QGIS settings dialog that allow you to manage the behaviour of multi-threaded rendering.

Etiquetado

Característica: Etiquetar elemenots múltiples veces

Long lines (such as contour lines or roads) can now be repeatedly labeled at regular intervals. One can choose between mm and map units for specifying the repetition interval. At the time of the release there is still an issue with «merge connected lines to avoid duplicate» setting.

Diseñador de Mapa

Característica: Mejoras a los elementos imagen del diseñador

The image item in composer is now “atlas friendly” - you can use an expression to define which image should be shown for each atlas page. You can also now set the resize mode (zoom, clip, stretch etc.) for the image in relation to its frame size and dimensions. You can also specify the placement of the image relative to its frame using the new placement item property.

image9

Característica: Modos de escala predefinidos para mapas del atlas

Cuando este trabajando con los elementos del mapa,usted puede especificar una escala predefinida para el mapa.Se utilizará la opción del mejor ajuste de la lista de escalas predefinidas en la configuración de propiedades de su proyecto (vea Proyecto –> Propiedades del Proyecto –> General –> Escalas del proyecto para configurar esas escalas predefinidas).

image10

Característica: Tablas de atributo mejoradas en el diseñador

Hemos hecho varias mejoras a la abilidad para mostrar tablas en sus bosquejos del diseñador:

  • Se ha adicionado soporte para reordenar columnas dentro de una tabla
  • Soporte adicionado para columnas basadas en expresiones
  • You can now set the alignment of individual table columns, and also specify the alignment for the table’s header cells
  • Los contenidos de tabla pueden ser filtrados por una expresión

image11

Característica: Mejoras generales del diseñador

There are a number of additions to the map composer to make life easier while working in map composition mode:

  • Botón adicionado para ver la extensión actual de elemento de mapa en la lona principal del mapa
  • Abilidad para exportar imágenes SVG desde el diseñador con capas
  • Definir estilo de unión y extremo para barras de escala
  • Soporte para establecer el estilo de unión de línea para marcos de elementos

image12

Característica: Mejoras a los marcos HTML

HTML Frames in the composer have been improved. There is a new add frame button which can be used to manually create multiple linked frames. We have also improved our page break logic making it less likely that you will get page breaks that cut through the middle of lines of text when paginating HTML frames.

Complementos

Característica: Complemento Cliente Catálogo MetaSearch

MetaSearch is a QGIS plugin to interact with metadata catalogue services, supporting the OGC Catalogue Service for the Web (CSW) standard. This plugin provides an easy and intuitive approach and user-friendly interface to searching metadata catalogues within QGIS and now ships by default with the QGIS core product.

Simbología

Característica: Estilo de llenado shapeburst

We have a great new render in QGIS 2.4. The shapeburst renderer will allow you to fill polygons with a gradient extending from the line edge towards the polygon interior. You can read more about shapeburst here.

image15

Característica: Opción para desplazar la ubicación de línea marcador

When using a marker line along a line or polygon edge, you can now specify an offset so that the marker line starts a set distance from the beginning of the line. If a marker line is set to «first vertex» or «last vertex» mode, than this offset will control how far along the line from the vertex the marker is placed.

image16

Característica: Nuevo visualizador de polígono invertido

A new renderer has been added for polygon features, allowing you to style everything outside your polygons. This can be useful for highlighting areas, or for creating cartographic masks. When used with new shapeburst style, you can now produce output as shown in the image for this entry.

Note: The new version of plugin mask helps to easily create mask layers from the current selection, label features only in those areas, and generate an automatic mask in Atlas map generation.

image17

Característica: Guardando y recuperando estilos con capas Spatialite

In the previous version was possible to save style with postgres layers, now will be possible for Spatialite layers too. This functions allow to embed different styles inside a spatialite container simplifying sharing data and their presentation. A video tutorial of this funcionality can be found here http://pvanb.wordpress.com/2014/05/15/saving-layer-styles-to-your-spatialite-database/
