Petascope - coordinates are translated wrong after subsetting

[Bang Pham Huu]

This one works:

for c in (test_nullvalues_no_update_map_mosaic) return encode(clip(c, POLYGON((2.39 7.07, 9.90 18.30, 20.72 8.07)) ), "tiff")

This one doesn't:

for c in (test_nullvalues_no_update_map_mosaic) return encode(clip(c[Lat(-19.9:50.0), Long(2.8:67.3)], POLYGON((2.39 7.07, 9.90 18.30, 20.72 8.07)) ), "tiff")

with error:

'SELECT encode(clip( c[46:77,-5:29], POLYGON((48 -8,53 -10,49 -16)) ), "tiff" , "{\"geoReference\":{\"crs\":\"EPSG:4326\",\"bbox\":{\"xmin\":6,\"ymin\":4,\"xmax\":18,\"ymax\":22}},\"nodata\":[1.0]}") FROM test_nullvalues_no_update_map_mosaic AS c'. Reason: Error: All polygons in the request lie outside the MDDObject's domain.
