KPG1_SCALX

Copies array values into another array, scaling them in the process

Description:

This routine copies values from one array to another, applying a linear scaling in the process. The input and output arrays can be of different data types.

Invocation

CALL KPG1_SCALX( SCALE, ZERO, BAD, EL, ITYPE, IP1, OTYPE, IP2, BADOUT, NBAD, STATUS )

Arguments

SCALE = DOUBLE PRECISION (Given)
The scale factor.
ZERO = DOUBLE PRECISION (Given)
The zero offset.
BAD = LOGICAL (Given)
If true there may be bad pixels present in the input array. If false it is safe not to check for bad values.
EL = INTEGER (Given)
The size of the input array.
ITYPE = CHARACTER ∗ ( ∗ ) (Given)
The HDS data type of the input array. All primitive HDS data types are supported.
IP1 = INTEGER (Given)
Pointer to the input array.
OTYPE = CHARACTER ∗ ( ∗ ) (Given)
The HDS data type of the output array. Must be an integer type (i.e. one of _INTEGER, _INT64, _WORD, _UWORD, _BYTE or _UBYTE ).
IP2 = INTEGER (Given)
Pointer to the output array.
BADOUT = LOGICAL (Returned)
True if there are any bad pixels in the output array.
NBAD = INTEGER (Returned)
The number of good input pixels that could not be accomodated within the dynamic range of the output data type, and were consequently set bad in the output array.
STATUS = INTEGER (Given and Returned)
Global status value
