The labeling engine has existed without major<br class="">architectural changes for 5-6 years since its introduction. Since then<br class="">lots of features were added and the original framework started to show<br class="">its age. The new API should allow for much more flexibility... things<br class="">like running labeling engine completely independently from the main<br class="">rendering loop, using anything as a source of label features (e.g.<br class="">raster cells?) and so on.</blockquote><div class=""><br class=""></div><div class="">Labelling raster cells would be awesome!</div><div class=""><br class=""></div><br class=""><blockquote type="cite" class=""> The old API (QgsPalLabeling) is of course<br class="">still available (and acts as a wrapper of the new API), but should get<br class="">removed in QGIS 3.<br class=""><br class=""><br class=""><blockquote type="cite" class="">My question is not totally innocent, I just launch funding to start QEP's<br class="">work on labeling improvements.
