Bborie Park 028ea10f03 Added a flag --with-raster-dblwarning so as to provide the software builder the option of enabling all the value truncation/clamping/conversion warnings, which can be many. The new default is to suppress those warnings. All appropriate regression tests have been updated.

Bborie Park 3f1a35b8fb Add ST_MapAlgebraFct for 2 rasters. This is the sibling of 2-raster ST_MapAlgebraExpr. Renamed RASTER_mapAlgebra2Expr to RASTER_mapAlgebra2 as both 2-raster ST_MapAlgebraExpr and ST_MapAlgebraFct call the same function.

 2011-08-25 23:23:46 +00:00
Bborie Park 56791ce3b5 Fixed the problem where having configure detect that GDAL has the GDALFPolygonize function does not cause the code to use GDALFPolygonize. This is due to the macro GDALFPOLYGONIZE not being set anywhere. So, it is now being set in raster_config.h.in and included in rt_core/rt_api.h. Had to update testapi.c as the geometries generated differ depending on whether or not GDALFPolygonize is used.
