Description
Label Alignment control (for lines) where separate polyline labels can be aligned vertically/horizontally for use as a map collar image, tic/labels/symbols that surround a map image vs being applied on top of the map itself. This ticket is for the label alignment specifically at this time.
The labeling by mapserver seems to jump around somewhat, probably based on whether there is a polyline vertice within the view or not and the amount of space available for placing the label in the output image. (Map grids are in many instances not rectangular and the map can also be rotated, so following the polyline for labeling is a must in this case).
See data attachment.
An example link aht demonstrates MapServers' varied label placement is here: http://pwultra5.ci.stpaul.mn.us/GILDA/collar_test/collar_01.html
