NAME
Scrolled_title - Creates movie titles. The titles can be scrolled, faded in, and/or faded
out. Foreground and background colors can be specified.
SYNOPSIS
The package Scrolled_title has eight user entry points, as follows: FTITLE, STITLE,
SLGETI, SLGETR, SLOGAP, SLSETI, SLSETR, and SLRSET.
FTITLE stands for "fixed titles" and is used when the following conditions are met:
• Each group of text lines is to fit on one frame (no scrolling).
• All test lines in a group are to be written in the same color.
• Vertical spacing of text lines is to be done automatically.
• Text lines are to be centered horizontally.
• There are to be no more than 80 characters per text line (including
Plotchar "function codes").
• In production mode, blank frames are to be generated before and after
each group of title frames.
• No more than 120 text lines are to be displayed on a single frame.
STITLE stands for "scrolled titles" and is used when the above conditions are not
met.
SLOGAP is used to generate blank-frame gaps in a manner consistent with FTITLE.
SLSETI and SLSETR
are used to set the values of "internal parameters" whose values affect the
behavior of FTITLE and/or STITLE.
SLGETI and SLGETR
are used to retrieve the current values of internal parameters.
SLRSET is ued to reset the values of all internal parameters of STITLE to the
original defaults.
C-BINDING SYNOPSIS

ACCESS
To use Scrolled_title routines, load the NCAR Graphics libraries ncarg, ncarg_gks,
ncarg_c, and ncarg_c, preferably in that order.
MESSAGES
The error messages described can be written to the output unit by routines in the package
Scrolled_title. Unless otherwise indicated, these errors are fatal and cause the user´s
program to terminate execution.
FTITLE - PREMATURE EOF ON CARD INPUT UNIT
FTITLE has encountered an end-of-file on the card input in a place where one
should not have been.
FTITLE - READ ERROR ON CARD INPUT UNIT
FTITLE has executed a FORTRAN READ statement and the "ERR=..." exit has been
taken.
FTITLE - TOO MANY INPUT CARDS IN GROUP
The first card of a title group contains a value of NCDS greater than 120.
FTITLE can't handle that many lines.
FTITLE - UNCLEARED PRIOR ERROR
When FTITLE was called, there was an unrecovered outstanding error. The routine
does not continue; it forces the error message to be printed and then
substitutes this one for it.
SLBKGD - ERROR RETURN FROM GQFACI: i
SLBKGD - ERROR RETURN FROM GQFAIS: I
A GKS routine has returned a non-zero error flag with value "i". This most
likely means that GKS is in the wrong state.
SLGCLR - TOO MANY COLORS DEFINED
More than 256 colors have been made known to STITLE. It has no room in which to
maintain information about them all.
SLGETI - UNCLEARED PRIOR ERROR
When SLGETI was called, there was an unrecovered outstanding error. The routine
does not continue; it forces the error message to be printed and then
substitutes this one for it.
SLGETR -- INVALID KEYWORD: xxx
The first argument in a call to SLGETR is not the name of one of the known
internal parameters of STITLE. This error message can occur as the result of a
call to SLGETI.
SLGETR - UNCLEARED PRIOR ERROR
When SLGETR was called, there was an unrecovered outstanding error. The routine
does not continue; it forces the error message to be printed and then
substitutes this one for it.
SLGWID - ERROR RETURN FROM GQACWK: i
A GKS routine has returned a non-zero error flag with value "i". This most
likely means that GKS is in the wrong state.
SLGWID - NO ACTIVE WORKSTATIONS
STITLE uses the routine SLGWID to determine the ID of the first active
workstation (to use in calls dealing with color) and it has found that there are
currently no active workstations at all.
SLOGAP - ERROR RETURN FROM GQTXCI: i
A GKS routine has returned a non-zero error flag with value "i". This most
likely means that GKS is in the wrong state.
SLOGAP - UNCLEARED PRIOR ERROR
When SLOGAP was called, there was an unrecovered outstanding error. The routine
does not continue; it forces the error message to be printed and then
substitutes this one for it.
SLRSET - UNCLEARED PRIOR ERROR
When SLOGAP was called, there was an unrecovered outstanding error. The routine
does not continue; it forces the error message to be printed and then
substitutes this one for it.
SLSCLR - TOO MANY COLORS DEFINED
More than 256 colors have been made known to STITLE. It has no room in which to
maintain information about them all.
SLSETI - UNCLEARED PRIOR ERROR
When SLSETI was called, there was an unrecovered outstanding error. The routine
does not continue; it forces the error message to be printed and then
substitutes this one for it.
SLSETR -- INVALID KEYWORD: xxx
The first argument in a call to SLSETR is not the name of one of the known
internal parameters of STITLE. This error message can occur as the result of a
call to SLSETI.
SLSETR - UNCLEARED PRIOR ERROR
When SLSETR was called, there was an unrecovered outstanding error. The routine
does not continue; it forces the error message to be printed and then
substitutes this one for it.
STITLE - ERROR RETURN FROM GQCLIP: i
STITLE - ERROR RETURN FROM GQCNTN: i
STITLE - ERROR RETURN FROM GQPLCI: i
STITLE - ERROR RETURN FROM GQPMCI: i
STITLE - ERROR RETURN FROM GQTXCI: i
A GKS routine has returned a non-zero error flag with value "i". This most
likely means that GKS is in the wrong state.
STITLE - UNCLEARED PRIOR ERROR
When STITLE was called, there was an unrecovered outstanding error. The routine
does not continue; it forces the error message to be printed and then
substitutes this one for it.
