[mapserver-users] Offset values from database
Hi, I'm trying to load offset X, Y data from the postgis database. Each feature has an offset value defined there. My mapfile (relevant part) looks like this: In the layer: DATAgeom_mercator from map_links using unique Id using SRID=900913 STYLE WIDTH 6 COLOR 0 255 0 ANTIALIAS TRUE ANGLE AUTO OFFSET [offsetX] [offsetY] END Please don't tell me the offsetX, Y values cannot be read from the database.

Re: [mapserver-users] Offset values from database
Hi David, I read that documentation before though. I was hoping it just hadn't been updated... Is this possibly a feature for 6.0 ? Are there any other ways how one could offset a feature in pixels, rather than in lat/long coords? Maybe I should elaborate on the original problem a little. Consider 2 line segments that lie above one another. The general idea is to 'offset' them a given x , y value, so they will both display next to one another, rather than on top of eachother. If you would however perform this code simply on lat/long values, it would imply, that when scaling your map at the most detailed zoom level, the lines would lie very far apart, and when zoomed out, they would appear to lie on top of eachother. I find it hard to believe that I would need to pre calculate all the data in order to obtain geometry objects for each zoom level. Maybe some veterans have some good insight in this :).

Re: [mapserver-users] Offset values from database
All, Wondering, would this work for INSIDE/OUTSIDE situations with regard to polygon drawing? Or is the left/right sides of the line strictly relying on the from/to aspects of how the polygon was drawn (clockwise/counterclockwise) This would be handy for off-setting to (ONLY) the inside of a polygon for example.

It must not be the case that at the furthest zoomlevel the lines are further apart. I've looked all over for this, but never really found a proper solution. I tried cartographic symbol drawing, but it only draws on the same side every time. Maybe I'm just doing it wrong :).

The issue with this, is that the underlying linestrings (the 2 that would lie on top of eachother), have different colors :(. So they have to be moved apart from one another. I have not found a way to do this with asymmetric line drawing either, as it will always offset to the same side. This is why i would need the offset value to be configurable in the database. I could select a different pixel offset for each line and they would always appear next to eachtoher (no matter what zoomlevel). I can elaborate on the problem more if I am a little too confusing !

Is this possibly a feature for 6.0 ? Are there any other ways how one could offset a feature in pixels, rather than in lat/long coords? Maybe I should elaborate on the original problem a little. Cons ider 2 line segments that lie If you would however perform this code simply on lat/long values, it would imply, that when scaling your map at the most detailed zoom level, the lines would lie very far apart, and when zoomed out, they would appear to lie on top of eachother.

[mapserver-users] need suggestions to implement simple dynamic zoom, pan select capabilities?!!
hi there... I've been using phpmapscript for on-the fly query displaying the resultant images... Now that I've got this problem that I tried using both mscross openlayers to display the image but somehow I cud not work it out.. I mean in both the above frameworks we need to specify the output image in the sort of URL tag-line style(wms) as below... eg:- http://localhost/index.php?mode=mapmap=/ms4w/apache/htdocs/india_roads1.mapmapext=60+7+102+38.5mapsize=640+480layers=SARDINIA%20india_ds%20IND_water_areas_dcw%20undefined Or may be I am wrong..Can we just specify the location of the resultant image and add all those dynamic zoom,pan functionality in 'Open Layers' i am sory If I am not clear enough but i need some suggestions for some simple script like mscross or soo where I need to add all those dynamic functions to my output image... that's it Thanks...!!@ -- View this message in context: http://osgeo-org.1803224.n2.nabble.com/need-suggestions-to-implement-simple-dynamic-zoom-pan-select-capabilities-tp5418885p5418885.html Sent from the Mapserver - User mailing list archive at Nabble.com. ___ mapserver-users mailing list mapserver-users@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/mapserver-users
