Symbology Tab
+
</H3>
+
 
+
<P>
+
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>
+
<DD>- a single style is applied to every object in the layer.<A NAME="321"></A>
+
   
+
</DD>
+
<DT><STRONG>Graduated symbol</STRONG>
+
<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>
+
<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>
+
 
+
 
+
<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>
+
 
+
<P>
+
 
+
<DIV ALIGN="CENTER"><A NAME="subfig:single_symbol"></A><A NAME="subfig:graduated_symbol"></A><A NAME="subfig:cont_color"></A><A NAME="subfig:unique_val"></A><A NAME="329"></A>
+
<TABLE>
+
<CAPTION ALIGN="BOTTOM"><STRONG>Figure:</STRONG>

+
<TR><TD>

<DIV ALIGN="CENTER">

+
  [Graduated symbol] [clip=true, width=0.4]vectorClassifyGraduated
+
<BR>  [Continous color] [clip=true, width=0.4]vectorClassifyContinous

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.
+
