Bug report #16514

Label distance incorrect for labels below a line

When placing labels along a polyline feature, setting the label distance does not have the correct effect for labels located beneath the line (i.e., when the top of the label is against the line).

To reproduce:
1. Label a polyline feature.
2. Select Line Orientation Dependent position, so that the label is sometimes placed beneath the line.
3. Set the label distance to a positive amount, such as 0.5 mm.

Labels that are located beneath the line will be closer to it than those that are above it. (See attached image, where all label distances are set to 0.5 mm.) By comparison, labels set by perimeter in a polygon feature appear to be located correctly.

I can't reproduce (on master). Are you able to attach a sample project which demonstrates this issue? It may only show up when combined with some other combination of label settings.

#2 Updated by Nathan Perry almost 7 years ago

Yes. I should note that with this project, the issue seems to affect the polygon layer as well as the line layer.

#3 Updated by Nyall Dawson almost 7 years ago

I can't reproduce on 2.18.7. Try updating?

#4 Updated by Nathan Perry almost 7 years ago

I have the most current version available, 2.18.2-1 for Mac OS.

I have also seen it on 2.18.2 on macOS. If I find some time I will try to install 2.18.7 on the same platform and test also there.

#6 Updated by Nathan Perry almost 7 years ago

2.18.7 is now released for Mac, and I can confirm the issue remains.

And by way of update, still occurring in version 3.0.

End of life notice: QGIS 2.18 LTR


QGIS 3.4 has recently become our new Long Term Release (LTR) version. This is a major step in our history – a long term release version based on the massive updates, library upgrades and improvements that we carried out in the course of the 2.x to 3x upgrade cycle.

We strongly encourage all users who are currently using QGIS 2.18 LTR as their preferred QGIS release to migrate to QGIS 3.4. This new LTR version will receive regular bugfixes for at least one year. It also includes hundreds of new functions, usability improvements, bugfixes, and other goodies. See the relevant changelogs for a good sampling of all the new features that have gone into version 3.4

Most plugins have been either migrated or incorporated into the core QGIS code base.

We strongly discourage the continued use of QGIS 2.18 LTR as it is now officially unsupported, which means we’ll not provide any bug fix releases for it.

You should also note that we intend to close all bug tickets referring to the now obsolete LTR version. Original reporters will receive a notification of the ticket closure and are encouraged to check whether the issue persists in the new LTR, in which case they should reopen the ticket.

If you would like to better understand the QGIS release roadmap, check out our roadmap page! It outlines the schedule for upcoming releases and will help you plan your deployment of QGIS into an operational environment.

The development of QGIS 3.4 LTR has been made possible by the work of hundreds of volunteers, by the investments of companies, professionals, and administrations, and by continuous donations and financial support from many of you. We sincerely thank you all and encourage you to collaborate and support the project even more, for the long term improvement and sustainability of the QGIS project.
