Strange effect when viewing EPSG:900913 WMS

[jbritton]

When trying to cache tiles in Google projection from http://openaerialmap.org/wms/ I get a very strange problem. See attached image.

.properties file for this layer:

# Image formats, use
imagemimes=image/png,image/jpeg,image/gif

# WMS backend
wmsurl=http://openaerialmap.org/wms/
wmslayers=world
wmsstyles=

# Tile profile
srs=EPSG:900913
bbox=-20037508.34,-20037508.34,20037508.34,20037508.34
transparent=true
metatiling=3x3

# Cache backend
cachetype=org.geowebcache.cache.file.FileCache?
filecachepath=/tmp

And is added in OpenLayers? using:

var layer = new OpenLayers?.Layer.WMS( title,
"http://10.11.64.107:5050/geowebcache/wms",
{

layers: layerName,

srs: 'EPSG:900913',
format: 'image/png',
styles: ,
tiled: 'true'

},
{

'isBaseLayer': true

}
);

Hi,

could you post or attach the entire HTML for the client (zip it up)? (I'm primarily interested in the Map object definition, but it'd be great if I could have exactly the same that you're looking at).

Definetly a high priority, thanks for reporting.

My code is all in different JavaScript? documents so it's a bit confusing sorry. Here is the code where I create the Map object though.

var options = {

projection: "EPSG:900913",
displayProjection: new OpenLayers?.Projection("EPSG:27700"),
units: "m",
maxResolution: 156543.0339,
maxExtent: new OpenLayers?.Bounds(-20037508, -20037508, 20037508, 20037508.34)

};
ChangesClient?.map = new OpenLayers?.Map(divName, options);

I wasn't able to reproduce this exactly, especially the diagonal warping. But a lot of the internals for tiling have been replaced, so there's a good chance this bug is gone.

Sorry about the slow response, GeoServer releases came in between.
