This is a repeated subject, Sorry but some one changed the subject of my previous thread before any one answers my question. \
I am using WorldWind caching. one of my caching using 256x256, but when I used OpenLayers with 256x256 it has very strange behavior, it downloaded the same tile more than once and draw it on different places on the same level. After several tests, I found that OpenLayers sends request for 2 tiles with different longlat with the same Row and col. example http://172.31.101.109:8080/servlet/getImageWWJ1?x1=51.375&y=25.96875&x=51.46875&y1=26.0625&level=4&row=618&col=1234 http://172.31.101.109:8080/servlet/getImageWWJ1?x1=51.46875&y=25.96875&x=51.5625&y1=26.0625&level=4&row=618&col=1234 these tow requests are for tow different tiles, as you can see the bounds for the tiles are different, but the column, row and Zoom level are the same, which return the same image . After requsting the tiles from on fly process (not cached tiles) which create the image based on bounds, every things worked fine. -- View this message in context: http://osgeo-org.1803224.n2.nabble.com/256x256-Levels-tp5086110p5086110.html Sent from the OpenLayers Dev mailing list archive at Nabble.com. _______________________________________________ Dev mailing list Dev@openlayers.org http://openlayers.org/mailman/listinfo/dev
