TextItem example 3
This example can be created using HLU C library calls, HLU FORTRAN
library calls, or NCL. It demonstrates how to set the background fill
color of a text item. The
names of the source files for this example are tx03c.c, tx03f.f, and
tx03n.ncl.
This module discusses how to create this plot using HLU function
calls or NCL. A resource file is included with this example, and it is
called tx03.res. This file shows
how to set the value of the text string, the text color, font, position, etc.
This example contains multiple frames. In each frame, the text string's
background color is changed by setting a color resource in the source
code and then redrawing the TextItem object.
A detailed discussion of how this example works appears in its source
code.
The HLU C program that generates this plot is called
tx03c.c.
The HLU FORTRAN program that generates this plot is called
tx03f.f.
The NCL script that generates this plot is called
tx03n.ncl.
This plot does not use any external data.
You can produce this example by using a C program (tx03c.c),
a FORTRAN program (tx03f.f), or an NCL script (tx03n.ncl). The examples are
installed in the following locations:
- $NCARG_LIB/ncarg/hluex/textitem/tx03c.c
- $NCARG_LIB/ncarg/hluex/textitem/tx03f.f
- $NCARG_LIB/ncarg/nclex/textitem/tx03n.ncl
You can copy this example and run it by typing
"ng4ex tx03c",
"ng4ex tx03f", or "ng4ex tx03n". A copy of the source file and resource
file will be placed in your current working directory. The source code
will be compiled and automatically run for you.
