Curved labels : max angle delta between letters - Githubissues

Author Name: Laurent Gasnier (Laurent Gasnier) Original Redmine Issue: 6673

Redmine category:labelling

Hi, In new labeling tool, it would be useful for the user to set the value of the max angle delta between letters (like MAXOVERLAPANGLE of Mapserver).

See attached screenshot test_anno_curv_roubion2.png: Black labels are drawn by a WMS Mapserver layer, red labels by QGIS.

The label "Le Roubion" is drawn only if MAXOVERLAPANGLE is set to 30 in .map file (with default value, it's not drawn).

See https://github.com/qgis/QGIS/issues/15916#issuecomment-495666966 for update on related issue.

Please test with ee12df2 to see if your labels now can match MapServer's. Some comparison screen snaps again would be nice.

Hi Larry, Thanks, it's all right. The label "Le roubion" is drawn with outside angle of 40. See attached file test_anno_curv_roubion_outside_angle_40 (black labels from mapserver, red labels from qgis).

Second example: "Canal de Bourgogne" and "La Vingeanne" are drawn with outside angle of 30 and letter spacing of 150 mapunits. See attached file test_canal_de_bourgogne. For missing Qgis labels in this second example, see #15846

Seeing your example in https://github.com/qgis/QGIS/issues/15916#issuecomment-495666966, your proposal of character averaging is interesting.

Hi Larry, confirmed here too, and really interested in the averaging solution to allow have readable labels for complex lines. See screenshot, that typically show big rivers, zoomed out, are the first to loose labeling, or to have overlapping characters.

Not in progress anymore, any funder welcome, QEP are all ready for those enhancements.

@haubourg Did #29994 fix this particular problem? the labeling gui has allowed for adjusting the maximum angle between curved characters, both inside and outside now for a number of versions.

Can we call this closed?

@gioman?

haubourg commented 3 years ago

Thanks for the cleanup! Yes we can close this.
