BURN_VALUE_FROM option for GDALRasterizeGeometries
|Reported by:||xenononarcticus||Owned by:||chaitanya|
This patch defines a BURN_VALUE_FROM option for GDALRasterizeGeometries. This option instructs GDALRasterizeGeometries(0 to derive the burn value from an alternate source. Currently the only recognized source is "Z", which is the interpolated Z coordinate of the source geometry, added to the explicit padfGeomBurnValue value. This is sensible for wkb[Multi]Point and wkb[Multi]LineString geometries but unimplemented for wkb[Multi]Polygon because interpolating Z within the filled polygon interior is extremely non-trivial.
These files are modified against a GDAL 1.6 release which does not appear to differ to greatly from the SVN trunk version.
