Hi,<br>May we develop an Opensource .ECW, for example .OCW, with sources of<br>epsilon!?<br>Because working with larges rasters as 100 000 x 100 000 is now current, and<br>it's not easy to manipulate .TIF > 30 Go!<br>Best regards<br><br>-----Message d'origine-----<br>Deа: Even Rouault [mailto:<a ymailto="mailto:even.rouault@mines-paris.org" href="mailto:even.rouault@mines-paris.org">even.rouault@mines-paris.org</a>] <br>Envoyща: vendredi 23 mars 2012 14:15<br>└а: Fred ETHEVE<br>Ccа: 'Jo┼╛e Dete─Нnik'; 'qgis-developer'<br>Objetа: RE: [Qgis-developer] RE: ECW!!!<br><br>Selon Fred ETHEVE <<a ymailto="mailto:fred.etheve@wanadoo.fr" href="mailto:fred.etheve@wanadoo.fr">fred.etheve@wanadoo.fr</a>>:<br><br>> Thank you, all,<br>> ECW/win was OK with trunk (1.9.90) until 2 days before new nightly...<br>> perhaps, since, gdal used has been 1.9???!!!<br><br>Yes, you should perhaps open a ticket (if not already done by someone
