C LATEST REVISION JULY 1984
C
C PURPOSE PWRITY IS A CHARACTER PLOTTING ROUTINE. IT HAS
C SOME FEATURES NOT FOUND IN WTSTR, BUT IS NOT AS
C FANCY AS PWRITX.
C
C
C USAGE CALL PWRITY(X,Y,ID,N,ISIZE,ITHETA,ICNT)
C
C ARGUMENTS
C
C ON INPUT X,Y
C POSITIONING COORDINATES FOR THE CHARACTERS TO
C BE DRAWN. X AND Y ARE USER WORLD COORDINATES
C AND ARE SCALED ACCORDING TO THE CURRENT
C NORMALIZATION TRANSFORMATION. ALSO, SEE ICNT.
C
C ID
C CHARACTER STRING TO BE DRAWN.
C
C N
C THE NUMBER OF CHARACTERS IN ID.
C
C ISIZE
C SIZE OF THE CHARACTER:
C . IF BETWEEN 0 AND 3, ISIZE IS CHOSEN AS
C 1., 1.5, 2., OR 3. TIMES AN 8 PLOTTER
C ADDRESS CHARACTER WIDTH.
C . IF GREATER THAN 3, ISIZE IS THE CHARACTER
C WIDTH IN PLOTTER ADDRESS UNITS.
C
C ITHETA
C ANGLE, IN DEGREES, AT WHICH THE CHARACTERS ARE
C PLOTTED (COUNTER CLOCKWISE FROM THE POSITIVE
C X AXIS.)
C
C ICNT
C CENTERING OPTION:
C = -1 (X,Y) IS THE CENTER OF THE LEFT EDGE
C OF THE FIRST CHARACTER.
C = 0 (X,Y) IS THE CENTER OF THE ENTIRE
C STRING.
C = 1 (X,Y) IS THE CENTER OD THE RIGHT EDGE
C OF THE LAST CHARACTER.
C
C ON OUTPUT ALL ARGUMENTS ARE UNCHANGED.
C
C ENTRY POINTS PWRY, PWRYSO, PWRYGT, PWRITY, PWRYBD
C
C COMMON BLOCKS PWRCOM
C
C REQUIRED LIBRARY THE SPPS.
C
C
C I/O PLOTS CHARACTERS.
C
C PRECISION SINGLE
C
C LANGUAGE FORTRAN
C
C HISTORY IMPLEMENTED FOR USE IN DASHCHAR.
C MADE PORTABLE IN JANUARY 1977
C FOR USE ON COMPUTER SYSTEMS WHICH
C SUPPORT PLOTTERS WITH UP TO 15 BITS RESOLUTION.
C CONVERTED TO FORTRAN77 AND GKS IN JULY, 1984.
C
C ALGORITHM DIGITIZATIONS OF THE CHARACTERS ARE STORED
C NTERNALLY AND ADJUSTED ACCORDING TO X, Y,
C ISIZE AND ICNT, THEN PLOTTED.
C
C TIMING SLOWER THAN WTSTR, FASTER THAN PWRITX.

C THE FOLLOWING DATA STATEMENTS CONTAIN THE DIGITIZATIONS OF THE
C CHARACTERS. THE CHARACTERS ARE DIGITIZED ON A BOX 6 UNITS WIDE AND
C 7 UNITS TALL. THIS INCLUDES 2 UNITS OF WHITE SPACE TO THE RIGHT OF
C EACH CHARACTER. IF KX=7, KY IS A FLAG -- KY=0 MEANS THE FOLLOWING
C KX AND KY ARE A PEN UP MOVE (ALL OTHERS ARE PEN DOWN MOVES), AND
C KY=7 MEANS THAT THE END OF THE DIGITIZATION FOR A PARTICULAR CHARAC-
C TER HAS BEEN REACHED.
