[Qgis-user] Label positioning options

[Tomas Straupis]

Hello

In layer option label tab there is a button in the upper right
corner (see attached picture).
It opens automated label positioning options menu.
https://docs.qgis.org/testing/en/docs/user_manual/working_with_vector/vector_properties.html#setting-the-automated-placement-engine

I have two questions about it:
1. Where can I find description of used methods: Chain, Popmusic
Tabu/Chain, FALP
2. Is there a reason why this dialog is so hidden? I was asked about
option to show partial labels (on by default) a number of times when
people simply could not find where to switch it off :-)

Thank you

Hi Tomas,

I managed to find this online if you are looking for techie understanding of the labelling placement methods.

Thank you, this answers the first question.

Because of different number of candidates and algorithms used,
default selected "Chain" is slowest but with best results (more
often). All Popmusic methods are medium ones for time/quality. And
FALP is fastest but with worst results.
