I always wondered what this was for..

What about hide it from the gui NOW, untill it is working for other formats.

As exporting a dxf layer is not encouraged anymore isn't it?
The 'new' way is to export the project, yes?

Hi,
Thank you Andreas, I can now stop expecting to create a shapefile with a
qml (or at least, keeping the original symbology) using this option.

About what to do, I fully agree with your suggestions: let's improve it if
doable (otherwise remove) and at least hide it from formats that are not
compatible to avoid users being confused.

Re: [Qgis-developer] Symbology export in save as feature

[Neumann, Andreas]

Hi Yves, 

This has mainly "historic" reasons. 

It was introduced specifically when saving QGIS layers to DXF through
OGR. I believe also the KML export is affected to some extent. 

Our first attempt to export QGIS layer to DXF went through OGR with OGR
feature  - however, this was too limited, and it was abandoned. 

"No symbology" means, simple black default lines 

"Feature symbology" means "Save with OGR Feature Styles" 

"Symbol Layer symbology" means "Save with OGR Feature Styles but export
the same geometry multiple times if there are multiple symbology symbol
layers used" 

Meanwhile the DXF export from QGIS goes through a native DXF writer -
without OGR, so the above approach was abandoned and hasn't been worked
on for some years now. 

- 

I hope this explains what it does, but as I said it is limited for
export to DXF/KML or potentially formats that support OGR feature styles
- formats that can handle styles. 

For QGIS 3.0 I see the following ways to get rid of this: 

1. keep it but improve it (unlikely) 

2. hide it for layers that don't support OGR feature styles (can be
combined with 1.) 

3. get rid of it completely (my preferred option if 1. does not happen) 

BTW: 2. could probably be done for QGIS 2.16 and 2.14 already, to have
fewer confused users ... 

Hope this explains it. 

What do others think? 

Andreas

[Qgis-developer] Symbology export in save as feature

[Yves Jacolin]

Hello,

Working in the "save as ..." feature documentation I wondering what "Symbology 
export" parameters mean. There are 3 possibilities: "No symbology", "Feature 
symbology" and "Symbol layer symbology".

Any idea what does it mean?

Thanks,

Y.
