Hi, I have never worked with image files having their origo at negative coordinates, but perhaps your problem is due to that? Maybe you should flip the signs in world files, like this: World file 1: - 4.553027622068700 0.000000000000000 0.000000000000000 4.553027622068700 -2547.418954547465546 -107603.978306161036016
I'm sorry if my idea is all wrong. -Jukka Rahkonen- ________________________________ Lähettäjä: UMN MapServer Users List puolesta: Ryan Ollerenshaw Lähetetty: to 7.9.2006 3:22 Vastaanottaja: [email protected] Aihe: [UMN_MAPSERVER-USERS] MapServer and World Files I have two world files that are associated with two different .pngs that should be very far apart, 50,000 meters according to the world files, but MapServer is rendering them one just a few meters apart, does anyone know why this might be?
