[Qgis-user] Labeling: Allow HTML Formatting, text-size and map units

[Thomas Schüttenberg]

Ha!
I found an other way around to do the trick, suitable for my use case at least:

1) increasing the (overall) text size setting on the text tab by 2/3
2) putting only the attributes/text strings of the second and following lines between <sub>...</sub> tags, which renders them about 2/3 smaler, i.e. same as before. 

The (reverse) result is a multi line label with the first line emphazised by its larger size! ;-)

"Bezeichnung" || '<p><sub>D ' || round("Deckelhohe",2) || '</sub></p><p><sub>S ' || round( "Sohlhohe" ,2) || '</sub></p>'

happy QGISing everyone!
Thomas
