Returns the X coordinate of the grid coordinate of the given world coordinates as an integer.

Signatures

RS_WorldToRasterCoordX(raster: Raster, point: Geometry)

RS_WorldToRasterCoordX(raster: Raster, x: Double, y: Double)

Raster

required

The input raster.

Double

The X coordinate (longitude).

Double

The Y coordinate (latitude).

Geometry

The point value.

An integer value.

SELECT RS_WorldToRasterCoordX(ST_MakeEmptyRaster(1, 5, 5, -53, 51, 1, -1, 0, 0), -53, 51) from rasters;

SELECT RS_WorldToRasterCoordX(ST_MakeEmptyRaster(1, 5, 5, -53, 51, 1, -1, 0, 0), ST_GeomFromText('POINT (-53 51)')) from rasters;

For non-skewed rasters, you can provide any value for latitude and the intended value of world longitude, to get the desired answer
