Well, I believe I've completed the functions for FV.01. The following
functions have been added:
ST_Band(rast raster, bandnums int[])
ST_AsGDALRaster(rast raster, format text, options text[], srs text)
ST_AsTiff(rast raster, options text[], srs text)
ST_AsPNG(rast raster, options text[], srs text)
ST_AsJPEG(rast raster, options text[], srs text)
Each of the above have several variations.
I've also added two ancillary function:
ST_getGDALDrivers()
for getting available and usable GDAL drivers on the server
ST_srtext(rast raster)
A bunch of the functions needed to get a spatial reference's
srtext/proj4text to pass to the GDAL raster, so this function was written.
I've added test cases to both test/core and test/regress though I think
the test cases could be built upon.
As my C skills were definitely rusty when I started this, please feel free
to correct my errors and more importantly, let me know what they are. I
will admit, the code was easy to understand and well documented!
Oh, I did make one tweak to raster/scripts/python/Makefile.in to accept
the variable DESTDIR for when building packages.
