Re: [Geoserver-users] Make hole in line to draw label

That's another change that might work, but it plays badly with priority support and conflict resolution (both require labels to be accumulated and handled at the end), so it's not a trivial change to implement (and it's basically how "holes" in lines would have to be implemented anyways) OK, thanks for clarifying this. On this subject, allowing some textsymbolizers to be taken out of the priority/conflict resolution pipeline would also solve some other problems (drawing geometries on top of labels being the most obvious one). i.e. having something like an x-textasgeometry vendor option to take a particular feature out of the labels pipeline and simply be drawn with no conflict resolution just like any other feature. Anyway, thanks for all your answers !

[Geoserver-users] Make hole in line to draw label
Hi list ! I'd like to label a line with a text in follow-line positionning. My problem is that with this simple style the label is not very readable because it is "stroked" by the line. So I'd like to make a hole (a gap), in the line at the place where the label will be drawn. I tried with a halo but it does not work well in my case because I have different background colors, and the halo has a predetermined color. So on white backgrounds a white halo works, but on blue background it does not. See here for a concrete example : https://i.imgur.com/39PQDX2.png Could anyone suggest me another way to achive this ? Thanks a lot Regards -- Arnaud ___ Geoserver-users mailing list Please make sure you read the following two resources before posting to this list: - Earning your support instead of buying it, but Ian Turton: http://www.ianturton.com/talks/foss4g.html#/ - The GeoServer user list posting guidelines: http://geoserver.org/comm/userlist-guidelines.html If you want to request a feature or an improvement, also see this: https://github.com/geoserver/geoserver/wiki/Successfully-requesting-and-integrating-new-features-and-improvements-in-GeoServer Geoserver-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/geoserver-users
