[postgis-users] point to raster conversion

[Rémi Cura]

Hey,
thanks for the answer.

I tried as you say,
it is not working and slow (several seconds for 50*50 pixels).
the function ST_ExtracToRaster just seems to do nothing.
(after using the function, st_value on any pixel return NULL, st_summary
also)

I have 2 bands of '32BF'.
I set the srid of both geom and raster to be the same.

Is there any way to set multiple pixels at once (and not do
st_set(st_set(..)))),
or a band constructor taking multiple pixels (an array for example)?

Cheers,

Rémi-C

Here is my test code :
