Raster Band properties

Zusammenfassung

The Describe function returns the following properties for raster bands. The Table and Dataset property groups are also supported.

For a raster band, the Describe dataType property returns a value of "RasterBand".

Eigenschaften

Eigenschaft	Erläuterung	Datentyp
height (Schreibgeschützt)	The number of rows.	Integer
isInteger (Schreibgeschützt)	Indicates whether the raster band has integer type.	Boolean
meanCellHeight (Schreibgeschützt)	The cell size in y direction.	Double
meanCellWidth (Schreibgeschützt)	The cell size in x direction.	Double
noDataValue (Schreibgeschützt)	The NoData value of the raster band.	String
pixelType (Schreibgeschützt)	The pixel type. U1—1 bit U2—2 bits U4—4 bits U8—Unsigned 8-bit integers S8—8-bit integers U16—Unsigned 16-bit integers S16—16-bit integers U32—Unsigned 32-bit integers S32—32-bit integers F32—Single-precision floating point F64—Double-precision floating point	String
primaryField (Schreibgeschützt)	The index of the field.	Integer
tableType (Schreibgeschützt)	The class names of the table. Value—Values in the table are used for values only, not for indexing. Index—Values in the table are used as indexes in the raster table. Invalid—Values are invalid.	String
width (Schreibgeschützt)	The number of columns.	Integer

Codebeispiel

Raster band properties example

The following stand-alone script displays some properties for a raster band:

import arcpy

# Create a Describe object from the raster band
#
desc = arcpy.Describe("C:/data/preston.img/Band_1")

# Print some raster band properties
#
print("Height: %d" % desc.height)
print("Width:  %d" % desc.width)
print("Integer Raster: %s" % desc.isInteger)
