NAME

       STITLE - Creates scrolled movie or video titles. It receives all input through the
       argument list.

UTILITY

       This routine is part of the Scrolled_title utility in NCAR Graphics.  To see the overview
       man page for this utility, type "man scrolled_title".

SYNOPSIS

        CALL STITLE (CRDS,NCDS,IYST,IYND,TMST,TMMV,TMND,MTST)

C-BINDING SYNOPSIS

       #include <ncarg/ncargC.h>

       void c_stitle (char *crds[], int ncds, int iyst,
       int iynd, float tmst, float tmmv, float tmnd, int mtst)

DESCRIPTION

CRDS (an input array, dimensioned NCDS, of type CHARACTER*n, where "n" is greater
than or equal to 21) is the "card input buffer". This array must be filled,
prior to calling STITLE, either by internal manipulations or by reading n-
character "cards". Each element of the array CRDS represents one line on the
scroll (or, sometimes, a continuation of a previous line) and contains the
following:

• Columns 1-5: MX, the X coordinate of the line of text on the scroll.
This is normally a value between 1 and 1024, inclusive. Exactly how the
line of text is positioned relative to the specified X coordinate
depends on the value of ICNT (in columns 14-15).

If the value -9999 is used for MX, it indicates a continuation line:
characters from columns 21 through "n" are just appended to the
characters from the previous card to form the line of text. Any number
of continuation cards may be used, but the total number of characters
in a line of text must not be greater than 512.

Trailing blanks are omitted from each card, including those that are
followed by a continuation card; thus, if there are to be blanks
between the characters from one card and the characters from a
continuation card, those blanks must be placed in columns 21 and
following of the continuation card.

On a continuation card, columns 6-20 are ignored.

• Columns 6-10: MY, the Y coordinate of the line of text on the scroll.
MY may range from -9999 to 99999.

• Columns 11-13: ICLR, the index of the color to be used for the line of
text. If this field is blank, the default foreground color specified
by the value of the internal parameter ´FGC´ will be used.

• Columns 14-15: ICNT, the centering option:

0 means "start the text at MX".

1 means "center the text about MX".

2 means "end the text at MX".

• Columns 16-20: SIZE, the desired size of the characters to be used in
writing the line. SIZE is given as a multiplier of a default height
specified by the value of the internal parameter ´PSZ´, the default
value of which is 21 (out of 1024). Values of SIZE from .75 to 2.5 are
recommended.

• Columns 21-n: Text for this line (or for continuation of a line when MX
= -9999).

NCDS (an input expression of type INTEGER) is the dimension of the array CRDS
(i.e., the number of card images in it).

IYST (an input expression of type INTEGER) is the Y coordinate that will be at the
center of the screen when the text is first displayed.

IYND (an input expression of type INTEGER) is the Y coordinate that will be at the
center of the screen when the text is last displayed.

TMST (an input expression of type REAL) is the time in seconds that the scroll will
be stationary at IYST. One second is recommended.

TMMV (an input expression of type REAL) is the time to move the scroll from IYST to
IYND. This should be the time required to read the text aloud at slow to
normal speed.

TMND (an input expression of type REAL) is the time that the scroll will be
stationary at IYND. One second is recommended.

MTST (an input expression of type INTEGER) is a switch to indicate whether this is
a "real" run or a "practice" run.

0 means "real run".

1 means "practice run".

During real runs, frames are created for the fade-in sequence (if the user has
turned on fade-in by setting the internal parameter ´FIN´ non-zero), the
stationary sequence at the start (if TMST is non-zero), the scrolling time (if
TMMV is non-zero), the stationary sequence at the end (if TMND is non-zero),
and the fade-out sequence (if the user has turned on fade-out by setting the
internal parameter ´FOU´ non-zero).

During practice runs, only selected frames are created: a frame for the fade-
in sequence (if fade-in is turned on), a frame for the stationary time at the
start, a set of frames representing the scrolling sequence, a frame for the
stationary time at the end, and a frame for the fade-out sequence (if fade-out
is turned on). Each has a legend indicating either for how many seconds the
frame will be shown or, if it is part of a scroll sequence, how many seconds
into the scroll time it occurs; during real runs, these legends are omitted,
of course.

Fade-in and fade-out are also affected by the values of the internal
parameters ´BGF´, which selects the type of fade-in/fade-out to be used for
the background color, and ´FGF´, which serves the same function for the
foreground color. (The older parameters ´SBK´ and ´SFG´ may still be
referenced, but their use is no longer recommended; setting ´SBK´ has the
effect of giving ´BGF´ an appropriate value and setting ´SFG´ has the effect
of giving ´FGF´ an apprpriate value.)

C-BINDING DESCRIPTION

       The C-binding argument descriptions are the same as the FORTRAN argument descriptions.

USAGE

       STITLE takes input through its argument list and generates graphic output that moves a
       body of text up through the viewing window. This is done by outputting the appropriate
       number of frames required to generate a movie sequence of a duration specified by you.

       At each frame STITLE skips plotting lines of text that are completely outside of the
       viewing window and clips those that are partially outside the window.

EXAMPLES

       Use the ncargex command to see the following relevant examples: fslfont, slex01, slex02,
       tstitl.

ACCESS

       To use STITLE or c_stitle, load the NCAR Graphics libraries ncarg, ncarg_gks, ncarg_c, and
       ncarg_c, preferably in that order.

MESSAGES

       See the scrolled_title man page for a description of all Scrolled_title error messages
       and/or informational messages.
