[mapserver-users] rendering a raster crossing the antimeridian through a WMS

[fred p]

Hello,

I do not manage do fully render in a Mapserver WMS a raster that crosses
the antimeridian when I request a -180°/+180° longitude bbox.

This is the request :
mapserv -nh
"QUERY_STRING=map=mapfile.map&layers=polar_orbiting_avhrr4&styles=&service=WMS&format=image%2Fpng&request=GetMap&height=400&width=800&version=1.1.1&bbox=-179.99%2C-89.99%2C179.99%2C89.99&exceptions=application%2Fvnd.ogc.se_inimage&srs=EPSG%3A4326&transparent=TRUE

In the result image, I only get the western side of the raster, near the
+180°. Nothing for the eastern part near the -180°.

How to solve this problem ?

This is a description of the raster :
