NAME

6       FL2INT - converts X and Y coordinates from the User Coordinate System
7       to the Metacode Coordinate System.
8

STATUS

10       Metacode units are no longer used in NCAR Graphics; thus, FL2INT is
11       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 "NCAR Graphics Fundamentals, UNIX Version" for a description
17       of these coordinate systems.
18
19       FL2INT continues to be provided for compatibility of early NCAR
20       Graphics codes.  If you are writing new code, we suggest that you use
21       user coordinates and fractional coordinates.  The routines CUFX and
22       CUFY will convert from user coordinates to fractional coordinates.
23       CFUX and CFUY will convert fractional coordinates to user coordinates.
24
25       The following definition of the Metacode Coordinate System is included
26       for the purpose of interpreting and converting codes:
27
28       The metacode coordinates of a point are integers IMX and IMY between 0
29       and 32767 inclusive.  The area addressed is a square in a "metacode
30       space" that is usually mapped into a square subset of the addressable
31       area of the plotting device.  Metacode coordinates were used in calls
32       to the routine PLOTIT and are returned in calls to FL2INT.

SYNOPSIS

35       CALL FL2INT (PX,PY,IX,IY)
36

DESCRIPTION

38       PX          (an input expression of type REAL) is the X coordinate of a
39                   point in user coordinates.
40
41       PY          (an input expression of type REAL) is the Y coordinate of a
42                   point in user coordinates.
43
44       IX          (an output variable of type INTEGER) is the X coordinate of
45                   the point in metacode coordinates.
46
47       IY          (an output variable of type INTEGER) is the Y coordinate of
48                   the point in metacode coordinates.

ACCESS

51       To use FL2INT, load the NCAR Graphics libraries ncarg, ncarg_gks, and
52       ncarg_c, preferably in that order.
