hello
I am dealing with java-jpa2-postgis(raster)
I tried to get an image from postgis(raster) as:
List list_rast = session.createSQLQuery("SELECT ST_AsPNG(rast) As rastpng FROM
geoslp5 where rid=184 ;").list();
and converting object to byte[]
and
with usual java process
ByteArrayOutputStream bos = new ByteArrayOutputStream();
... //
bytes = bos.toByteArray ();
But resulting image file(png) is defective ?
What may the probable problems ?
Do you have any recommendations ?
regards
