[Qgis-user] How to convert qml style file from version 3.28.6 to 3.16.14

2024-01-08 Thread Rigola C Jaume INFORMACIO DE BASE via QGIS-User 
For reasons that are not relevant to this discussion I have two versions of 
QGIS installed on my Desktop (3.16.14-Hannover & 3.28.6-Firenze).

I have realised that when a project is saved at 3.28.6-Firenze version, the 
symbology styles are lost if opened with QGIS 3.16.14-Hannover. I've browsed 
for solutions, and I read that that's an issue since version 3.22, but I 
couldn't find a way to solve it.

Does anyone know how to save the layer stlyles on 3.28.6-Firenze  so they can 
be recovered on 3.16.14-Hannover? (Maybe a version conversor, or a QML file 
conversor)

Many thanks in advance,

Jaume

Hi Jaume,
I'm making the assumption that your styling is saved in the Project File and 
not as a Style for the Layer itself.
Might I suggest that you create a default style for each layer, this can easily 
be done by going to the Layer Properties and clicking on the Style button on 
the bottom Left and selecting Save as Default. This will result in a default 
style for the Layer so it doesn't matter what version of QGIS you use, or 
indeed what project you load the layer into, it will use the default style. You 
can also manually do this, by saving the style with the same name as the 
dataset.

The same can be done for all layers, Vector or Raster. It will even do it for 
PostGIS Layers, saving the style in a new table called style in the public 
schema in your Database.

I hope the above helps.
Kind Regards,

Richard

I wasn't aware that you can work around the backward compatibility problem
by saving style files, but if that works you might find a processing
algorithm to save default style could save you a lot of time.  The
geoproc.com processing algorithms plugin has one, as well as another for
saving and loading multiple styles.
And I posted another algorithm to save default style at:
