Ive adapted this code so that I can get tiles....but the x y values are now
wrong
I´m getting this..
http://DOMAIN/gwc/service/tms/1.0.0/zgb%3ARROP08@EPSG%3A900913@png/8/7/46.png
when I should be getting this..
http://DOMAIN/gwc/service/tms/1.0.01.0.0/zgb%3ARROP08@EPSG%3A900913@png/10/541/686.png
so 8/7/46.png instead of 10/541/686.png
How can I get this correct?...is this to do with resolutions?
yours,
Rob

Betreff: [OpenLayers-Users] TMS parsing algorithm
Hi,
I am trying to display a tms layer using openlayers by modifying some code
which displays cloudmade layers
I have some code which tries to construct the tile but it is failing throwing
this error...
400: Unable to parse number For input string: "zgb:RROP08@EPSG:900913@png8"
from tms/1.0.0/zgb:RROP08@EPSG:900913@png8/134/81.png
I have obviously got it totally wrong.....Could anyone direct me to the
documentation or say how to correctly parse the wms path?
yours,
Rob
