Hi Andrés,
Your characters are not displaying using our primitive
"stick figure" fonts which are the default for VisAD.
However, you can get them to display if you specifiy a
Font in the TextControl associated with your ScalarMap
to Display.Text. I have modified visad/examples/Test69.java
to test with your characaters. Try copying something like
its code to your application:
ScalarMap tmap = new ScalarMap(text, Display.Text);
display.addMap(tmap);
TextControl tcontrol = (TextControl) tmap.getControl();
Font font = new Font("Serif", Font.PLAIN, 60);
tcontrol.setFont(font);
tcontrol.setSize(2.0);
I have attached a new version of Test69.java with your
characters.
Since your characters display OK in your email, they must
have ASCII codes. Thus someone energetic could add them to
the stick figure font in visad/PlotText.java, in the
"float[][] charCodes" array. Given a Java "char" type from
a String (e.g., str.charAt(i)), then:
int k = str.charAt(i) - 32;
if (k < 0 || k > 127) continue; // invalid - just skip
// now the sequence of plot points for the character is
// defined by the float[] array in charCodes[k], you'll
// have to study the code and the existing characters
// to understand the "simple" format
If anyone does add new characters to the "float[][] charCodes"
array, we will be happy to incorporate them into the system.
Or you can just use new Font("Serif", Font.PLAIN, 60) in your
TextControl.
Cheers,
Bill
