AW: [mapserver-users] Re: symbol position moving when using angle
Hi Bart, may be this is what you are looking for: >From the map file documentation: LABEL ... POSITION [ul|uc|ur|cl|cc|cr|ll|lc|lr|auto] Position of the label relative to the labeling point (layers only). First letter is "Y" position, second letter is "X" position. "Auto" tells MapServer to calculate a label position that will not interfere with other labels. With points, MapServer selects from the 8 outer positions (i.e. excluding cc). With polygons, MapServer selects from cc (added in MapServer 5.4), uc, lc, cl and cr as possible positions. With lines, it only uses lc or uc, until it finds a position that doesn't collide with labels that have already been drawn. If all positions cause a conflict, then the label is not drawn (Unless the label's FORCE a parameter is set to "true"). "Auto" placement is only available with cached labels.

Hi Bart, the Migration Guide says that the keyword POSITION can also be used in the STYLE section since version 6.0.

There is a difference of exactly 256. So NODATA is 256 according to ArcMap, but Mapserver seems to map it to 0, etc. for all other values. Does anyone know how to solve this? TIA.
