 Priority:  medium          |   Milestone:  PostGIS 2.0.0
Component:  postgis raster  |     Version:  trunk

----------------------------+-----------------------------------------------
 The following fails to properly burn the specified value to the generated
 raster.  If both scales are >= 1, there are no problems.  Need to see how
 gdal_rasterize utility works around the problem.

 {{{
 SELECT ST_Value(ST_AsRaster(ST_MakePoint(0, 0), 0.1, 0.1), 1, 1);
 }}}

 {{{
 SELECT ST_Value(ST_AsRaster(ST_MakeLine(ARRAY[
         ST_MakePoint(0, 0),
         ST_MakePoint(1, 0)
 ]), 0.1, 0.1), 1, 1);
 }}}
