[mapserver-users] Transparent lines at -180 when rendering BlueMarble data

[Jason Beverage]

Hi all,

I'm using mapscript to render some blue marble data into tiles.  The issue
I'm seeing is that occasionally I get a 1pixel wide transparent column along
-180 at different zoom levels.  For example, if I render a 256x256 tile by
setting the map's extent using:
map.setExtent (-180.0, -22.5, -157.5, 0.0)

I'm getting the attached image with the transparent column.

The extent of the file itself via gdalinfo is -180,-90,180,90 so it does
cover the whole world and there are no transparent pixels in the data
itself.

Thanks!

Jason
