<div dir="ltr" align="left"><font color="#0000ff" size="2" face="Arial"><span class="317151208-23092011">You perhaps want to achieve a map presenting the whole world once and then some extra from the second round in the margins like
<a href="http://www.openstreetmap.org/?lat=59&lon=-39&zoom=1&layers=M">http://www.openstreetmap.org/?lat=59&lon=-39&zoom=1&layers=M</a>? It might well be that the transformation functions consider that for EPSG:3395 the maximum values really are the bounds
reported at <a href="http://spatialreference.org/ref/epsg/3395/">http://spatialreference.org/ref/epsg/3395/</a> and values outside the value range are invalid. I have no idea about how you could get your map out from WMS. Could you consider composing it from
pieces somehow?</span></font></div>

Hello<br>
Nobody has got an idea whether I am wrong somewhere or there is a problem in the image or ... ?<br>
I add the result is OK in EPSG:4326 whatever the bbox is and it is OK too in EPSG:3395 provided the extent longitude is smaller than 360°. However when it is higher...<br>
Thanks in advance<br>

I am trying to serve an image in Mercator projection (EPSG:3395) with an extent larger than "360° in longitude" but I get a truncated and reversed in longitude image.<br>
Do I make a mistake somewhere?<br>
Thanks for your help<br>
