Finally, I use MVT mode successfully. Here is what I did if it can help
(and I will probably read my own lines in few months !)
- installed Mapserver with MS4W 5
- followed instructions (readme.txt) to replace old mapserver & Apache with
new ones. Not as easy as it sounds because...
- had to install the VSC++ in the ms4w/tmp, not the most recent one, for
Apache (otherwise php conflict according to the log).
- in httpd.conf of Apache change DocumentRoot to define my storage of
mapfiles.
- in c:/ms4w/ms4w.conf, defined my own MS_MAP_PATTERN to stick to the
mapfile root just above.
- in mapfile :
- OutputFormat mvt according to the doc
https://mapserver.org/output/tile_mode.html
- did not use tile_map_edge_buffer nor tile_metatile_level or in
Openlayers there were problems of rendering as polygons where "moving" from
here to there on the map each time I moved the map.
- At last in openLayers : in a VectorTileSource, set an url like this :
http://
.../cgi-bin/mapserv.exe?MAP=C:/ms4w/Apache/site/mapfile/vue_prescription_pgts_wfs.map&"
+
"mode=tile&tilemode=gmap&tile={x}+{y}+{z}&LAYERS=prescription&map.imagetype=mvt"
and now it works fine.
