[Geomoose-users] requested image size 2.6 vs 2.2

[Jim Klassen]

Just an FYI: I made ticket #169 for this.

When a user pans, the neighboring tiles appear instantly since they have already been buffered.  From what I noticed, at 2.6 only enough tiles are requested to cover the map itself.  Therefore on a small pan users have to wait to see the tiles.

In 2.6 the ratio is set to 1.  This means that the requested image is exactly the same size as the map window.  This is good because the image is smaller, but a user pans over just a small amount a new image is requested from the server.

It also makes tilled images appear much faster - since the tiles would start to load before a user could pan to the area.  Is there any way to configure 2.6 so that we can request larger images so that GM 2.6 behaves more like 2.2?
