[Qgis-user] QGIS 2.18 -Changing layer rule-based style transparency

[Tudorache, Marian]

Hi,

I have a polygon type vector layer with rule-based style.
I need to change programmatically the layer transparency.

I used the following code:
layer = iface.activeLayer()
layer.setTransparency(80)
layer.triggerRepaint()
This works only if I want to see layers which are under the active one but it 
does not work for the features inside active layer.

When there are identical polygons which overlap within active layer, I can only 
see the top one. If I select a polygon which is underneath it is not displayed 
as selected.
I can make it work if I manually open the layer style and double click on rule 
to open Rule properties and set the transparency for the rule.
How can I change the rule transparency programmatically?
Thank you,
Marian

[Qgis-user] Creating PDF bookmarks in Atlas created by print composer?

[magerlin]

I am about to produce an Atlas in QGIS with 130 maps each showing one road.

It is created as an atlas in print composer and I have a label field in the
layout which includes the road name (from the coverage layer). I use single
file export to get one pdf document of 130 pages, all with identical layout.

I would love to make this document having PDF bookmarks leading to all the
road names for easy reference from the pdf bookmarks panel.

I can use html coding in the label but have still not found a solution on
how to get the bookmarks.

I have found one workaround in creating each map as a single pdf with the
name of the road. Then by merging all 130 pdf to one in PDFsam
(https://pdfsam.org/download-pdfsam-basic/) I can get bookmarks from the
filenames

Any ideas on how to do it directly from QGIS?
