Description:
This function creates a FrameSet containing the NDF-special Frames, GRID, PIXEL,
FRACTION and AXIS, appropriate to an NDF with the supplied dimensionality and pixel index
bounds. Optionally, AXIS information can be propagated from a supplied NDF.
Invocation
CALL KPG1_ASNDF( INDF, NDIM, DIM, LBND, UBND, IWCS, STATUS )
Arguments
INDF = INTEGER (Given)
An NDF from which to propagate AXIS information. May be
NDF__NOID, in which case the AXIS Frame in the returned FrameSet will describe the
default AXIS coordinate system (i.e. pixel co-ordinates).
NDIM = INTEGER (Given)
The
number of pixel axes in the modified FrameSet.
DIM( NDIM ) = INTEGER (Given)
The
indices within INDF corresponding to each of the required NDIM axes.
LBND( NDIM ) =
INTEGER (Given)
The lower pixel index bounds in the modified FrameSet.
UBND(
NDIM ) = INTEGER (Given)
The upper pixel index bounds in the modified FrameSet.
IWCS = INTEGER (Returned)
Pointer to a new FrameSet holding GRID, FRACTION,
PIXEL and AXIS Frames describing the supplied NDF bounds, plus AXIS information
from the supplied NDF.
STATUS = INTEGER (Given and Returned)
The global status.
