Rodriguez, I can report having a similar problem, but have noticed that seeems to be related to use of some of the other settings in the LABEL section. I don't recall the details exactly unfortunately, but if you are trying to reproduce a test case then try different values of MINDISTANCE and POSITION in particular (including AUTO and not present). I know something I did at some point was causing LABEL_NO_CLIP to not function, but I don't recall what.

The second level of logging is: CONFIG MS_ERRORFILE path_to_mapserver.log which provides more detail, but you usually have to configure DEBUG ON (or DEBUG 1-5) as well for this to be useful.

Since the wiki is pretty much broken now (moved, unchanged base href and so on), I'm assuming the outline was done with a filled bar symbol with negative gap under the road line since it looks similar to the solution I eventually wound up with to get the borders without closing the ends of the segments.

I read the RFC in the mapserver 5.4 documentation and it talks about plans to extend functionality of GEOMTRANSFORM (which it incorrectly refers to as GEOTRANSFORM and GEOMETRYTRANSFORM, incidentally), and I *think* either the distance or buffer might achieve most of what I need with ANGLE AUTO - to draw a parallel line segment.

[mapserver-users] cartographic lines
Hello all, i've come across a cosmetic issue I'm trying to solve and looking for advice. Specifically this relates to drawing street/road lines, although I guess it relates to any type of cartographic line. I'm using mapserver 5.4.1 using AGG renderer with quantize enabled: OUTPUTFORMAT NAME'AGG_Q' DRIVER AGG/PNG IMAGEMODE RGB # FORMATOPTIONQUANTIZE_FORCE=ON FORMATOPTIONQUANTIZE_NEW=ON FORMATOPTIONQUANTIZE_DITHER=OFF FORMATOPTIONQUANTIZE_COLORS=256 END Mapserver was built with --with-experimental-png (which does indeed resolve the colour variations between tiles that I reported earlier). I'm drawing street layers with elipses, but I'm now wondering if that is the best way to achieve the result, being an inner colour with a border, viz: STYLE COLOR [border_color] SYMBOL road_line SIZE $x END STYLE COLOR [surface_colour] SYMBOL road_line SIZE $x-2 END where road_line is a simple SYMBOL elipse. The problem I'm seeing is two-fold. Firstly, the ends are rounded, which is not desirable where roads of different classes (defined in different layers) join. I think this can be solved by drawing all streets in the same layer and using different classes with EXPRESSION statements, but my brief experiment with this resulted in a large detriment effect on rendering speed. If it matters, the layers are in PostGIS (and appropriately indexed). So my question is, is there a better or at least an alternative way of drawing roads with borders which does not result in this problem? The second problem is that I'm trying to add OPACITY to some layers, such as tunnels, so that they either appear underneath other objects or at least allow other objects to show through. However - and it may be related to the use of symbols to draw the roads - this results rendering as shown in the attached file, with elipses of a different shade appearing where objects intersect. Can this be avoided (perhaps by using a different method for drawing road lines)? Note that since I am rendering a flat tile which includes a background I'm using RGB rather than RGBA and I suspect this may affect rendering of OPACITY in layers. However I can't seem to find the magic that will render a background colour other than black (and yes, I'm using IMAGECOLOR in the MAP section, but it seems to have no effect when rendering with transparency).

[mapserver-users] Mapserver rendering with 24 bit colour
Greetings all, Once I completed upgrading to mapserver 5.4, I decided I'd give the new AGG renderer a try. To date I have been using the GD renderer in 8 bit color mode. One problem I had with it the renderer, and my main motivation to use the AGG renderer (apart from what appears to be an overall improvement in appearance) was that any layer containing ANGLE FOLLOW within a class label definition caused php/mapscript to crash rendering meta tiles (for ka-map, if that matters). The AGG renderer solved that problem immediately and it works flawlessly in that respect. However, as a by-product of changing renderer, the metatiles produced by mapserver differ slightly in colour. Some agree exactly to the RBG colours I am providing, others are rendered with slight variations, and when viewed on the web it becomes fairly obvious where the meta tile borders are. I have tried both OUTPUTFORMAT NAME'AGG_Q' DRIVER AGG/PNG IMAGEMODE RGB FORMATOPTION QUANTIZE_FORCE=ON FORMATOPTION QUANTIZE_DITHER=OFF FORMATOPTION QUANTIZE_COLORS=256 END and OUTPUTFORMAT NAME'AGG' DRIVER AGG/PNG IMAGEMODE RGB END but both produce the same results. I have even tried fiddling with the FORMATOPTIONs in the AGG_Q block to no effect. I've double-checked the mapscript used to render the tiles to make sure that the correct output format is being selected. Is there a known solution to this? How can I force all tiles produced to use the exact same colour settings? I would have thought the quantize option would resove it, although obviously this would have a slight detrimental side-effect for anti-aliasing. My map file does include various ANTIALIAS options (which the document states are ignored in AGG mode) so I can fall back to GD rendering should I ever get ANGLE FOLLOW working again.
