RE: [mapserver-users] mapserv 5.6 - 6.0 label symbol change
I can verify the code in 6.0 that let's this happen- it's deliberate (in msDrawLabelCache()). I have to do some more digging to understand the rationale. At first glance I prefer the 5.6 behavior as well.

RE: [mapserver-users] .NET SWIG Mapscript - Bug or Doc issue
Looking at mapserver.h the opacity attribute of a styleObj is exposed via SWIG. So it should be mutable, so there's a documentation problem. You can read the mapfile, change the value and save the mapfile as a quick test. Can you try another language?

And I have a report that when trying to use this via .NET mapscript that it does not seem to work. layerObj opacity seems to work just fine. So, is this: a. a code bug or oversight in the SWIG wrappers b. something specific to .NET code c. a documentation bug d. something else all together I'm happy to create appropriate bugs as needed.

Re: [mapserver-users] mapserv 5.6 - 6.0 label symbol change
Steve, The 5.6 behavior was more user friendly, but the work around is simple enough that I don't think the issue deserves much attention. I put a FILTER on the label field and got back to where I wanted to be. LABELITEM NUMBER FILTER ([NUMBER]) As always, thanks for your knowledge and insight.

[mapserver-users] layerObj.setFilter parser error
If I use layerObj.setFilter ( (point.id = 1) ), mapObj.OWSDispatch gives an error: msTokenizeExpression(): Expression parser error. Parsing time value failed. msParseTime(): Regular expression error. Unrecognized date or time format (). It works correctly with layerObj.setFilter ( ( id = 1) ) or layerObj.setFilter ( point.id = 1 ). FILTER ( point.id = 1 ) in mapfile also works. This is of course only a simple example, I need both fully qualified column name and parenthesis. It seems to be a bug. Do you know any simple trick, how to get it working for a presentation tomorrow morning? Version 6.0.1.

[mapserver-users] performance question - labeling roads with shields
Hello, On my Application I currently am using two layers to draw my roads. The first one is a line layer that draws the road itself. The second is a annotation layer that draws the labels and the road shields. Both layers have the same source dataset. My concern is that my application is taking a performance hit since the road file is being read twice. If there is a performance hit by reading the same data file twice, is there a way combine the line layer and annotation layer into a single layer that has both the road symbology, and labels that have shields? Layer Roads ... DATA MyRoads TYPE LINE CLASS NAME 'State Highway' EXPRESSION A20 STYLE COLOR 0 0 0 SYMBOL 'plainline' SIZE 5 END #style STYLE SYMBOL 'plainline' SIZE 1 COLOR 255 0 0 END #style END #class ...

[mapserver-users] RE: performance question - labeling roads with shields
Hi Mark: With the changes in label styles in 6.0 you should be able to combine the layers, for example: LAYER NAME 'major_roads' ... CLASS NAME 'Interstates' STYLE # orange lines with a brownish outline WIDTH 4 MAXWIDTH 8 MINWIDTH 4 COLOR 242 191 36 OUTLINECOLOR 187 176 157 OUTLINEWIDTH 1 END LABEL TYPE TRUETYPE SIZE 7 ... STYLE SYMBOL 'interstate_shield.png' END END END END That should be all there is to it- all in one pass.
