Hello Andreas,<br>
<br>
Thank you very much for your complete answer.<br>
<br>
Actually, I reached my goal using rule based renderers.<br>
<br>

Benoit,

<br>
It depends. Yes - you can mix transparent and opaque features. For
each color you can also set the opacity/transparency value.
<br>
<br>
However, if two features overlap and you use transparency on the
feature level, you can see the features shine through - whereas
when the transparency would be on the symbol level (which isn't
implemented yet in QGIS) you would first composite all elements in
a symbol level and then apply the opacity on the whole group. See
<a class="moz-txt-link-freetext" href="http://www.w3.org/TR/2011/REC-SVG11-20110816/masking.html#ObjectAndGroupOpacityProperties">http://www.w3.org/TR/2011/REC-SVG11-20110816/masking.html#ObjectAndGroupOpacityProperties</a>
for the difference. In
<a class="moz-txt-link-freetext" href="http://www.w3.org/TR/2011/REC-SVG11-20110816/images/masking/opacity01.png">http://www.w3.org/TR/2011/REC-SVG11-20110816/images/masking/opacity01.png</a>
- if you look at the bottom row of circles - the second pair of
circles has the opacity on the group of two circles, whereas the
third pair has opacity on every single element. I hope you can see
the difference.
<br>
<br>
It would be very cool if QGIS could have a more fine-grained
opacity - new opacity on symbol level and new opacity on a whole
group of layers. It would make the cartographic options even
better ;-)

<br>
<br>
Is it possible to have semi-transparent and opaque features
within the same layer ?
<br>
<br>
Best regards,
