## Name

ST_WorldToRasterCoordY — Returns the row in the raster of the point geometry (pt) or a X and Y world coordinate (xw, yw) represented in world spatial reference system of raster.

## Synopsis

`integer ST_WorldToRasterCoordY(`raster rast, geometry pt`)`;

`integer ST_WorldToRasterCoordY(`raster rast, double precision xw`)`;

`integer ST_WorldToRasterCoordY(`raster rast, double precision xw, double precision yw`)`;

## Description

Returns the row in the raster of the point geometry (pt) or a X and Y world coordinate (xw, yw). A point, or (both xw and yw world coordinates are required if a raster is skewed). If a raster is not skewed then xw is sufficient. World coordinates are in the spatial reference coordinate system of the raster.

Changed: 2.1.0 In prior versions, this was called ST_World2RasterCoordY

## Examples

    SELECT rid, ST_WorldToRasterCoordY(rast,20.5) As ycoord,
            ST_WorldToRasterCoordY(rast,3427927.8,20.5) As ycoord_xwyw,
            ST_WorldToRasterCoordY(rast,ST_GeomFromText('POINT(3427927.8 20.5)',ST_SRID(rast))) As ptycoord
    FROM dummy_rast;

     rid |  ycoord   | ycoord_xwyw | ptycoord
    -----+-----------+-------------+-----------
       1 |         7 |           7 |         7
