function RegisterRasterStyledLayer from rasterlite2 'no such function'

[José Sánchez]

Hi,

I'm trying to follow this rasterlite2 exercise from here:

https://www.gaia-gis.it/fossil/librasterlite2/wiki?name=ETOPO1

but when I try to execute

SELECT RegisterRasterStyledLayer('etopo1_dem',

   ...> XB_Create(XB_LoadXML('./etopo1_styles/etopo.xml'), 1, 1));

It says 'no such function'

Thanks,

Hi José,

RasterLite2 is not yet a "stable" package and continued
to evolve during recent times; the sad consequence is
that unhappily the tutorials are not always correctly
updated.

in recent versions that specific function changed its
name, that now is SE_RegisterRasterStyledLayer()

sorry for any inconvenience,
Sandro

Great and thanks,

But according to the function definition:

SE_RegisterRasterStyledLayer   ( coverage_name String , style_id Integer ) : Integer

it should be alright, but it is still giving me an error:

SELECT SE_RegisterRasterStyledLayer('etopo1_dem', XB_Create(XB_LoadXML('./etopo1_styles/etopo.xml'), 1, 1));

-1

Thanks,

There can be many reasons for this:

1) file-path is invalid (I assume this is not the case)

2) etopo.xml style-validation failed (the most likely)
