NAME¶
CPCHCF - Called by Conpack routines when a constant field is detected. The
default version does nothing. A user-written version may be supplied to
provide control as the constant-field message is drawn.
SYNOPSIS¶
CALL CPCHCF (IFLG)
DESCRIPTION¶
- IFLG
- (INTEGER, input) is positive if an action is about to be taken, negative
if an action has just been completed. The action in question is defined by
the absolute value of IFLG, as follows:
- •
- The value 1 implies the determination of the size of the label (by means
of a call to PLCHHQ, in the package Plotchar, with ANGD=360.).
- •
- The value 2 implies the filling of the box around the label, which is done
before the drawing of the label itself.
- •
- The value 3 implies the drawing of the label (by means of a call to
PLCHHQ, in the package Plotchar).
- •
- The value 4 implies the drawing of the box around the label, which is done
after the drawing of the label itself.
USAGE¶
The routine CPCHCF is not to be called by the user. It is called several times
by Conpack while a constant-field label is being drawn. The default version of
CPCHCF does nothing. A user-supplied replacement may change attributes such as
color and line width (by calling the SPPS routine SETUSV or the appropriate
GKS routines). The text of the label being written may be retrieved by means
of a "CALL CPGETC ('CTM',CVAL)". The text of the label may be
changed by means of a "CALL CPSETC ('CTM',CVAL)"; this should only
be done during a call with IFLG = 1 or 3 and, if it is done for one of those
two values, it should also be done for the other. When CPCHCF is called, the
parameter 'ZDV' will have been set to the value of the field; its value may be
retrieved and used by CPCHCF.
ACCESS¶
To use CPCHCF, load the NCAR Graphics libraries ncarg, ncarg_gks, and ncarg_c,
preferably in that order.
