NAME

6       GETSI - returns the exponents which define the plotting range in the
7       plotter address unit coordinate system.
8

STATUS

10       Plotter Address Units (PAUs) are no longer used in NCAR Graphics; thus,
11       GETSI is considered an obsolete routine.
12
13       The current recognized coordinate systems are GKS world coordinates,
14       GKS normalized device coordinates, NCAR Graphics fractional
15       coordinates, and NCAR Graphics user coordinates.  See the NCAR Graphics
16       document "The Use of X/Y Coordinates in NCAR Graphics" for a
17       description of these coordinate systems.
18
19       GETSI continues to be provided for compatibility of early NCAR Graphics
20       codes.
21
22       The following definition of the PAU Coordinate System is included for
23       the purpose of interpreting and converting PAU codes:
24
25       The plotter coordinates of a point are integers IPX and IPY, where IPX
26       is between 1 and 2**MX and IPY is between 1 and 2**MY.  MX and MY are
27       internal parameters of SPPS; each has the default value 10.  Values of
28       MX and MY can be set by routine SETI and retrieved by routine GETSI.

SYNOPSIS

31       CALL GETSI (IX,IY)
32

DESCRIPTION

34       IX          (an output variable of type INTEGER) is the X axis exponent
35                   for plotter coordinates defining a range of 1 to 2**IX - 1.
36                   IX has a default value of 10.
37
38       IY          (an output variable of type INTEGER) is the Y axis exponent
39                   for plotter coordinates defining a range of 1 to 2**IY - 1.
40                   IY has a default value of 10.
41

ACCESS

43       To use GETSI, load the NCAR Graphics libraries ncarg, ncarg_gks, and
44       ncarg_c, preferably in that order.
