| + | |
− | QGIS supports a number of symbology renderers to control how
| + | |
− | vector features are displayed. Currently the following renderers
| + | |
− | are available:
| + | |
− | | + | |
− | <P>
| + | |
− | <DL>
| + | |
− | <DT><STRONG>Single symbol</STRONG></DT>
| + | |
− | <DD>- a single style is applied to every
| + | |
− | object in the layer.<A NAME="321"></A>
| + | |
− |
| + | |
− | </DD>
| + | |
− | <DT><STRONG>Graduated symbol</STRONG></DT>
| + | |
− | <DD>- objects within the layer are
| + | |
− | displayed with different symbols classified by the values of a
| + | |
− | particular field.<A NAME="322"></A>
| + | |
− |
| + | |
− | </DD>
| + | |
− | <DT><STRONG>Continuous color</STRONG></DT>
| + | |
− | <DD>- objects within the layer are
| + | |
− | displayed with a spread of colours classified by the numerical
| + | |
− | values within a specified field.<A NAME="323"></A>
| + | |
− |
| + | |
− | </DD>
| + | |
− | <DT><STRONG>Unique value</STRONG></DT>
| + | |
− | <DD>- objects are classified by the unique
| + | |
− | values within a specified field with each value having a
| + | |
− | different symbol.<A NAME="324"></A>
| + | |
− | </DD>
| + | |
− | </DL>
| + | |
− | | + | |
− | <P>
| + | |
− | To change the symbology for a layer, simply double click on its legend
| + | |
− | entry and the vector Layer Properties dialog will be
| + | |
− | shown.<A NAME="327"></A>

− | Style Options <A NAME="sec:style_options"></A> <A NAME="341"></A>
| + | |
− | Within this dialog you can style your vector layer. Depending on the selected
| + | |
− | rendering option you have the possibility to also classify your mapfeatures.
| + | |
− | | + | |
− | <P>
| + | |
− | At least the following styling options apply for nearly all renderers:
| + | |
− | <DL>
| + | |
− | <DT><STRONG>Outline style</STRONG></DT>
| + | |
− | <DD>- pen-style for your outline of your feature. you can
| + | |
− | also set this to 'no pen'.
| + | |
− |
| + | |
− | </DD>
| + | |
− | <DT><STRONG>Outline color</STRONG></DT>
| + | |
− | <DD>- color of the ouline of your feature
| + | |
− |
| + | |
− | </DD>
| + | |
− | <DT><STRONG>Outline width</STRONG></DT>
| + | |
− | <DD>- width of your features
| + | |
− |
| + | |
− | </DD>
| + | |
− | <DT><STRONG>Fill color</STRONG></DT>
| + | |
− | <DD>- fill-color of your features.
| + | |
− |
| + | |
− | </DD>
| + | |
− | <DT><STRONG>Fill style</STRONG></DT>
| + | |
− | <DD>- Style for filling. Beside the given brushes you can
| + | |
− | select Fill style? texture and click the
| + | |
− | button for selecting your own fill-style. Currently the fileformats
| + | |
− | *.jpeg, *.xpm, and *.png are supported.
| + | |
− | </DD>
| + | |
− | </DL>
| + | |
− | | + | |
− | <P>
| + | |
− | Once you have styled your layer you also could save your layer-style to a
| + | |
− | separate file (with *.qml-ending).
| + | |
− | To do this, use the button Save Style .... No need to say that
| + | |
− | Load Style ... loads your saved layer-style-file.
| + | |
− | | + | |
− | <P>
| + | |
− | If you wish to always use a particular style whenever the layer is loaded,
| + | |
− | use the Save As Default button to make your style the default. Also,
| + | |
− | if you make changes to the style that you are not happy with, use the Restore
| + | |
− | Default Styel button to revert to your default style.
| + | |
− | | + | |
− | <P>
| + | |
− | Vector transparency <A NAME="sec:vect_transparency"></A> <A NAME="354"></A>
| + | |
− | QGIS allows to set a transparency for every vector layer. This can be done with
| + | |
− | the slider Transparency020mm inside the symbology tab (see fig. <A HREF="node15.html#fig:vector_symbology">10</A>).
| + | |
− | This is very useful for overlaying several vector layers.
| + | |
