NAME¶
GETSI - returns the exponents which define the plotting range in the plotter
address unit coordinate system.
STATUS¶
Plotter Address Units (PAUs) are no longer used in NCAR Graphics; thus, GETSI is
considered an obsolete routine.
The current recognized coordinate systems are GKS world coordinates, GKS
normalized device coordinates, NCAR Graphics fractional coordinates, and NCAR
Graphics user coordinates. See the NCAR Graphics document "The Use of X/Y
Coordinates in NCAR Graphics" for a description of these coordinate
systems.
GETSI continues to be provided for compatibility of early NCAR Graphics codes.
The following definition of the PAU Coordinate System is included for the
purpose of interpreting and converting PAU codes:
The plotter coordinates of a point are integers IPX and IPY, where IPX is
between 1 and 2**MX and IPY is between 1 and 2**MY. MX and MY are internal
parameters of SPPS; each has the default value 10. Values of MX and MY can be
set by routine SETI and retrieved by routine GETSI.
SYNOPSIS¶
CALL GETSI (IX,IY)
DESCRIPTION¶
- IX
- (an output variable of type INTEGER) is the X axis exponent for plotter
coordinates defining a range of 1 to 2**IX - 1. IX has a default value of
10.
- IY
- (an output variable of type INTEGER) is the Y axis exponent for plotter
coordinates defining a range of 1 to 2**IY - 1. IY has a default value of
10.
ACCESS¶
To use GETSI, load the NCAR Graphics libraries ncarg, ncarg_gks, and ncarg_c,
preferably in that order.
