Hi Mathias,
What happens if you try in your request: &TILE=0+0+0 (and remove the
&map.imagetype part) ?
(that's what I did while documenting steps for the page
https://mapserver.org/output/tile_mode.html )
Recent MS4W versions also include an MVT demo as well as a local.map
test file, so you could:
- first try in your browser
http://127.0.0.1/cgi-bin/mapserv.exe?MAP=/ms4w/apps/local-demo/local.map&MODE=tile&TILEMODE=gmap&TILE=0+0+0&LAYERS=countries
(you should see a map image of the world countries in your browser)
- then add your OUTPUTFORMAT for MVT into local.map, and then try:
http://127.0.0.1/cgi-bin/mapserv.exe?MAP=/ms4w/apps/local-demo/local.map&MODE=tile&TILEMODE=gmap&TILE=0+0+0&LAYERS=countries&map.imagetype=mvt
If that fails, you might have to upgrade your MS4W version.
But if that works, I would then paste your "prescription" layer into
local.map, and reload that same request in your browser.
thanks,
(and thanks for using MS4W)

I try to create MapBox vectorTile to use with Openlayers.
Here is my mapfile :

First, I test with a request like :
http://.../mapserv.exe?MAP=C:/ms4w/Apache/site/mapfile/
vue_prescription_pgts_wfs.map&mode=tile&tilemode=gmap&tile={12}+{447}+{1988}&layers=prescription&
All I get is :
msDrawMap(): Image handling error. Unable to initialize image.
msPrepareImage(): Image handling error. Unable to initialize image.
SUPPORTS=PBF is in mapserv.exe -v
EXTENT is that of my data.
I did not find any leads in RFC-119 (but I don't understand all that I
read.)
I have no idea how to solve this problem.
Cordialement,
