[mapserver-users] Newer version of Freetype causing font rendering problems
Hi, We have found that version 2.4.10 of Freetype causes text through MapServer to render differently (and not as nicely) as v2.3.9 of Freetype. Whilst we have got round this issue by reverting to the earlier version of Freetype, we are concerned that this may cause issues in the future if the old version either stops working on newer operating systems, or if Mapserver stops linking to it. I have attached a couple of screenshots (hopefully these will come through on the list), and i can provide example shapefile and mapfile etc if required... I guess what I'm looking for is feedback as to whether this is a known issue, and whether it should be submitted as a bug report to Mapserver (if so, how?), or to Freetype?

Re: [mapserver-users] Still impossible to force labels inside their polygons?
Label expressions might turn out to be useful here. Just thinking out loud... I mean we might be able to extend things and define expressions where you can write tests like the intersecting a label bbox against the parent shape. Expressions with multiple labels work like classes and are executed in order. Bigger issue is having to cache original geometries as part of the label cache. --Steve From: mapserver-users-boun...@lists.osgeo.org [mapserver-users-boun...@lists.osgeo.org] on behalf of Brent Fraser [bfra...@geoanalytic.com] Sent: Wednesday, December 12, 2012 12:49 PM To: Mark Volz Cc: mapserver-users@lists.osgeo.org Subject: Re: [mapserver-users] Still impossible to force labels inside their polygons? Mark, Sounds ok (it took me a while to realize you meant the BBOX of the polygons, not the label!). My world of sophisticated labeling would include some way of having the mapfile specify the order of applying the rules, but currently there is no way to do procedural things in a mapfile, just set parameters. On second thought, I guess the CLASS list evaluates things in a particular order; perhaps the same technique could be used in label placement: LABEL CHECKLABELFIT true # Check BBOX of label against polygon outline (not just BBOX of polygon) LOCATION# --- first label attempt (Case A,B) --- POSITION cc,ul,uc,ur END LOCATION# --- next label attempt (Case C) --- ANGLE auto END LOCATION# --- next label attempt (Case D) --- LEADER : END END END And I'd like to factor in preferring labeling in areas of no other linework, but that may take some thought...

The CHECKLABELFIT keyword is mostly to verify that a label falls inside the actual polygon as opposed to the BBOX, which would help avoid ambiguity on labels. I don't think CHECKLABELFIT would be mutually exclusive to any method of trying to find different label positions. In your comments you have the term If it doesn't fit. CHECKLABELFIT could be used to specify if we consider if the label fits according to the BBOX or the polygon. For example: A: Calculate the default location of the label in the polygon. If CHECKLABELFIT is on: only place the label if it falls inside the polygon. If CHECKLABELFIT is off: only place the label if it fits in the BBOX If the label could not be placed, and TRYALTERNATELABELS is on: B: Try different positions in the polygon UL,UC,UR, etc. If CHECKLABELFIT is on: only place the label if it falls inside the polygon. If CHECKLABELFIT is off: only place the label if it fits in the BBOX If a label still could not be placed: C: Rotate the label. If CHECKLABELFIT is on: only place the label if it falls inside the polygon. If CHECKLABELFIT is off: only place the label if it fits in the BBOX. If a label could not be placed after rotating the label D. Try using a leader line. / Place Polygon annotation outside polygon. Use situations: CHECKLABELFIT=FALSE, TRYALTERNATELABELS=FALSE: label the map as fast as possible. CHECKLABELFIT=TRUE, TRYALTERNATELABELS=FALSE: make sure labels fit in their polygons, but don't worry about labeling everything. CHECKLABELFIT=FALSE, TRYALTERNATELABELS=TRUE: try to label as many items as possible, use the BBOX as label ambiguity is okay. CHECKLABELFIT=TRUE, TRYALTERNATELABELS=TRUE: try to label as many items as possible, and make sure that the labels fit inside their polygons.

Mark, A simple solution sounds good as long as it can fit into a strategic plan (I don't really have a plan for improving the polygon labeling, just a desire!). On major releases of Mapserver I try to push the limits of its cartography by comparing its output to hand-composed pdfs of Canadian Topo maps [1] (not fair I know). One of the stumbling blocks I've run into is the labeling of polygons and I've speculated on the use of rules-based labeling. Here's my list of rules from a comment on RFC 77 [2]. Allow for alternate label positions. While this is likely beyond the scope of RFC 77, perhaps it could be taken into account in design and implementation for later addition. Basically I'd like more flexibility (rule-based?) in labeling polygons: A.
[mapserver-users] Mapserver CSRS support
I have issue with my WMS service when using a source raster layer that is in EPSG:2958 - NAD83(CSRS) / UTM zone 17N srs. The issue is that Mapserrver (proj) does not apply a gridshift when requesting the layer in a different projection - UTM z17n NAD83. I have a gridshift file for this transformation however there is no way to apply it to the output that I am aware of.

Subject: [mapserver-users] Retrieve function values from Postgres
Hello,
is it possible for mapserver to question a function in a postgres geo
database ?
i.e. this query string inside postgres works:
select * from get_aerosol_data('gas_db', 25.5, '2005-3-2 00:00',
'2006-3-5 00:00');
If it is possible how to translate this into mapserver mapfile syntax ?
Thanks and Regards

[mapserver-users] Map inset, anyone tried this?
All, Wild thought here . . . I'm wondering about how to approach the need to add a map inset to a MapServer call. I know I can make separate calls and stack some maps on top of each other, but I'm wondering now about using a TRANSFORM of coordinates to put a Map Inset window into a Mapserver call in some way? One thought was to use a SQL call to PostGIS and transform things in some fashion that way. Another might be a method for defining a window, and then adding in a MapServer parameter to use a MAPfile to populate it. This might also lead to some capabilities with respect to making some interesting embedded Legends, since the populating aspect might be a simple URL to populate the defined window in the map. With MapServer making the call, the window could even be treated as a label object and label collisions could be handled as well . . . hmmm, remember, I did say wild. :c) In the back of my mind (for some number of years now) I've wanted the capabilities to actually draw things via a MapServer call in some form. A Map Inset window with a tail, similar to OpenLayers or Google Popups for example, would be the best description I can think of. Anyone tried anything like this? I can see this being interesting as a capability especially for doing spatial reports (Which I'm in the middle of designing right now . . .)
