Configures the skews of a raster object on the X and Y scales in the spatial reference system.
Syntax
rasterST_SetSkew(raster raster_obj, float8 skewX, float8 skewY)
rasterST_SetSkew(raster raster_obj, float8 skewXY)Parameters
Parameter | Description |
raster_obj | The name of the raster object. |
skewX | The skew of the raster object on the X scale. |
skewY | The skew of the raster object on the Y scale. |
skewXY | The skew of the raster object on the X and Y scales. This parameter specifies the same skew on the X and Y scales. |
Examples
UPDATE raster_table
SET raster_obj = ST_SetSkew(raster_obj, 0.3, 0.6)
WHERE id = 2;
SELECT st_skewx(raster_obj), st_skewy(raster_obj)
FROM raster_table
WHERE id = 2;
