zero - Create a cube and fill with a constant value (default 0)
ZERO creates a standard 3-dimensional cube and fills the core
with a user specifed fill value.

PROGRAMMER: Kris Becker, U.S.G.S., Flagstaff, AZ

ParmDescriptionDefault
TO
Output cube name
(default extension is .CUB)
NONE
OTYPE
Output pixel type
(valid: 1,2,3)
3
DIMS
Core dimensions.
(samples, lines, bands)
NONE
FORMAT
Format of output cube
BSQ - band sequential format
BIL - band interleaved by line
"BSQ"
FILL
Value assigned to output cube
(default 0)
0.0
NULL
Set core values to NULL value
(YES,NO)
NO

ADDITIONAL NOTES:

ParmDescription
TO
Specify the disk file name of the created Cube. The file
name convention is standard host operating system syntax.
OTYPE
Output pixel data type.  Permitted values are:

    1 - 8-bit  (integer with type conversion parameters)
    2 - 16-bit (integer with type conversion parameters)
    3 - 32-bit (floating point)

DIMS
Specifies the dimensions of the core.  DIMS corresponds
to the number of Samples, Lines and Bands, respectively.
FORMAT
Output format of the Cube. The cube can be organized
as band-sequential (BSQ), or band-interleaved by line
(BIL)
FILL
Specifies the value that the cube will be initialized with.
Note that the scaling parameters used for all types of cubes
is a scale of 1.0 and a base of 0.0.  Hence, some of the
specified values for certain requested output bit types may
result in a fill of saturation values.  For example, if
OTYPE=1 (8-bit) and FILL=-1.0, then the cube will result
in all pixels attaining the low saturation value.  Likewise,
FILL = 257.0 will result in the cube to have high saturation
values.
NULL
This parameter used to set the core to null values rather
than the fill value. If NULL=NO (default) then the cube
is set to the FILL value. If NULL=YES, the core pixels are
set to the NULL value (the FILL parameter is ignored)
