Description
I have the following CLASS definition for labeling a polygon with a symbol and text. It behaves correctly with POSITION UL|CL|LL|LC|LR|CR|UR|UC but places the text on the the SYMBOL if I use POSITION AUTO.
LAYER NAME "area_landmarks" TYPE POLYGON TILEINDEX "tidx-AREALM" PROJECTION "+proj=longlat +ellps=GRS80 +datum=NAD83" #EPSG: 4269 END MAXSCALEDENOM 2500000 CLASSITEM "MTFCC" LABELITEM "FULLNAME" CLASS EXPRESSION /^K2561/ # Golf STYLE COLOR "#C9DFAF" END LABEL STYLE SYMBOL "golf" SIZE 24 END MAXSCALEDENOM 200000 TYPE TRUETYPE FONT "sans" SIZE 7 COLOR "#24471C" OUTLINECOLOR "#E5F0D8" PARTIALS FALSE MINDISTANCE 250 MINFEATURESIZE 10 BUFFER 4 POSITION AUTO # UL|CL|LL|LC|LR|CR|UR|UC all work: PRIORITY 4 WRAP " " ALIGN CENTER END END END
I have attache an image showing the placement of the symbols and text for the various cases.

yes, I would agree with that. This only impacts POSITION AUTO so if we skip CC with a marker it should work great like the manual test cases.

Thomas,
Here is a mapfile I built for testing the label position with a symbol. You might want to add it to msautotest stuff.

trunk looks good this your checkin. Closing this as fixed.
for polygon type layers, the first position tried is CC, which is why you're seeing collisions. We should adapt the code so that CC is not the default position if a marker is also defined.
