Re: [mapserver-users] MapCache Larger tiles, reduce number of files
Are you sure you have the set the tile size correctly in OpenLayers?
Because if OL is requesting tiles that you don't have it sounds like
that is the reason.
And if you do load tile and there is a miss-match, then I would expect
the resolution of be off.
Here are a few links that might help:

Jean-Philippe,
I don't think it works like that. Resolution is determined by zoom
factor so you generate metatile at that resolution then you chop that
metatile in tiles of whatever size you specify. So resolution is
controled by zoom not tile size.

[mapserver-users] MapCache Larger tiles, reduce number of files
Hi,
With MapCache, I want to generate the tiles that will be copied to a mobile
device, on a viewer created with OpenLayers.
When generating a large extent, with multiple levels of zoom, the files count
is really big, so I want to reduce the number of files by increasing the tile
size. I've made a test with tiles 512x512, but I've realized that the
resolution must be changed when changing tiles size. So, the tiles are bigger,
but changing the resolution make generating the same number of files.
I'm open for workaround and other tricks.

[mapserver-users] Embedbed Web form on a Map.
Hi, Was wondering if anyone has seen/built an example of embedding (or overlaying) a web form on top of a map. Basically I want to be able to edit attributes of a feature right in the map. Click the feature, and a form appears related to the actual feature. Labels /FORM elements follow a polyline for example. My first aplication will apply some Address range setting form elements to each end of a line for editing. I’ve already figured out how to display the elements in a raster output through Mapserver, but still pondering the web (edit) form aspects. Some initial thoughts: * Could a output template be devised to output a rotated (CSS) web form with the approriate pixel spacing of the elements right from Mapserver. I think so, even so far as rotating individual form elements in the result. Seems like a bit of an uphill battle though . . . * Could a LandScape/Portrait FORM have a rotated background image applied to it, based on the preplanned end point locations on the map. This actually seems the quickest to implement, but I wonder if it helps at all with other feature types, or if it would be specific to this first need. It would be nice to implement a method for any feature type for example, like being able to edit the edges of a polygon. My first need: [***] = FORM elements (attributes for editing) [min_left_add] [street_name][max_left_add] O - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - O <— line representation [min_right_add] [street_type] [max_right_add] or O [max_left_add]|[max_right_add] | | | | [street_name]|[street_type] | | | | [min_left_add]|[min_right_add] O Anyway still pondering . . . . bobb ___ mapserver-users mailing list mapserver-users@lists.osgeo.org https://lists.osgeo.org/mailman/listinfo/mapserver-users
