RS_BandPixelType

Introduction: Returns the datatype of each pixel in the given band of the given raster in string format. The band parameter is 1-indexed. If no band is specified, band 1 is assumed.

Note

If the given band index does not exist in the given raster, RS_BandPixelType throws an IllegalArgumentException.

Following are the possible values returned by RS_BandPixelType:

1. REAL_64BITS - For Double values
2. REAL_32BITS - For Float values
3. SIGNED_32BITS - For Integer values
4. SIGNED_16BITS - For Short values
5. UNSIGNED_16BITS - For unsigned Short values
6. UNSIGNED_8BITS - For Byte values

Format: RS_BandPixelType(rast: Raster, band: Integer = 1)

Since: v1.5.0

SQL Example

SELECT RS_BandPixelType(RS_MakeEmptyRaster(2, "D", 5, 5, 53, 51, 1, 1, 0, 0, 0), 2);

Output:

REAL_64BITS

SELECT RS_BandPixelType(RS_MakeEmptyRaster(2, "I", 5, 5, 53, 51, 1, 1, 0, 0, 0));

Output:

SIGNED_32BITS

SELECT RS_BandPixelType(RS_MakeEmptyRaster(2, "I", 5, 5, 53, 51, 1, 1, 0, 0, 0), 3);

Output:

IllegalArgumentException: Provided band index 3 is not present in the raster
