<p class="MsoNormal">Steve,<br>
<br>
Looks very promising. A few points:<br>
<br>
1. Label priority within a group. Someone may want to assign priority to labels withing the group ("always (try to) label the well_id, and label the well_production if there is room"). I guess this could be handled with the current method of using two LAYERs
with different label PRIORITY.<br>
<br>
2. Allow for alternate label positions. While this is likely beyond the scope of the RFC, 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:<br>
<br>
A. Try to place label in polygon. If it doesn't fit:<br>
B. Rotate anno to fit inside a polygon. If it doesn't fit:<br>
C. Place polygon annotation outside polygon<br>
<br>
3. I think we need a section in our RFCs for related Tickets. E.g.:<br>
<br>
<a href="http://trac.osgeo.org/mapserver/ticket/3009">http://trac.osgeo.org/mapserver/ticket/3009</a> getLabelPoint() does not work for polyline and point layers.<br>
<a href="http://trac.osgeo.org/mapserver/ticket/2981">http://trac.osgeo.org/mapserver/ticket/2981</a> Need a way to define a POSITION array for labeling.<br>
<a href="http://trac.osgeo.org/mapserver/ticket/3335">http://trac.osgeo.org/mapserver/ticket/3335</a> Label style support<br>
<a href="http://trac.osgeo.org/mapserver/ticket/2866">http://trac.osgeo.org/mapserver/ticket/2866</a> Drawing 'Straight' label with LABEL_NO_CLIP, if 'Follow' label drawing fails.<br>
<a href="http://trac.osgeo.org/mapserver/ticket/1355">http://trac.osgeo.org/mapserver/ticket/1355</a> labelInImage and buffer usage<br>
<br>
and indicate if/how the RFC will impact the tickets.<br>
<br>
Thanks!<br>
