Description
Hi,
The new labeling system doesn't display all the labels of a layer, see the joined file for an example using an integer field for labels. The parameters used are free placement and no obstacles, activating colliding and candidate labels modify nothing.
The old labeling system displays them all, I can reproduce this problem with other layers.
History
#1 Updated by Jean-Roc Morreale about 14 years ago
The bug is due to topological errors in the polygons, the labels appears when it is corrected (not self-intersection). This behavior is making the use of the new label engine harder on gps data collected with centimetric gps, if the surveyor makes a small wrong move then the data has to be manually corrected to be labeled (automatic cleaning does not give good result).
The old labelling engine works on both uncorrected an corrected data.
#2 Updated by Giovanni Manghi almost 13 years ago
- Target version changed from Version 1.7.0 to Version 1.7.4
#3 Updated by michele zanolli almost 13 years ago
- Crashes QGIS or corrupts data set to No
- File labels_test.zip added
- Affected QGIS version set to master
Maybe this problem is related to the following:
I am having problems with curved labeling with my layer of lines (see attached shapefile).
Enable the advanced option "Show all labels (i.e. including colliding labels")
Try to display labels with "parallel" placement option --> ok, all labels are displayed.
Try to display labels with "curved" placement option --> I can see only 1 or 2 labels.

Hi Michele, this missing curved labels should be another issue, please file a separate ticket.
