Description:
Transform a
set of double precision data coordinates into world coordinates using a transformation
stored in the database. The picture identifier signifies which picture contains the required
transformation structure. If this identifier is negative then the current picture is used. If no
transformation structure is found then the identity transformation is used, i.e. the world
coordinates equal the data coordinates.
Invocation
CALL AGI_TDDTW( PICID, NXY, DX, DY,
WX, WY, STATUS )
Arguments
PICID = INTEGER (Given)
Picture identifier
NXY =

of x data coordinates
DY = DBLE(NXY) (Given)
Array of y data coordinates
WX =
DBLE(NXY) (Returned)
Array of x world coordinates
WY = DBLE(NXY) (Returned)
Array of
y world coordinates
STATUS = INTEGER (Given and Returned)
The global status
