Nikolaos: Moved over to the user list (trust you are subscribed).
To answer your question - if you turn off conflict resolution the labels are just blindly drawn (as if they were symbols). So you could use this as a way to use emoji to represent point locations for example :P When conflict resolution is used each label "reserves" a bounding box as it is generated. The rendering engine takes all the proposed labels and does its best to draw them in a pleasing manner on the screen. You have a whole bunch of control on how this happens using vendor options when styling. -- Jody Garnett On Thu, 21 Nov 2019 at 05:34, Jody Garnett <jody.garn...@gmail.com> wrote: > You may wish to set a high label priority to strongly prefer labels from > one layer. > > We should move this discussion to geotools user list please.
