JTextField crops text when using custom TrueType font. How to make it display text normally?

Question

So, the problem is definitely with the font. Question is how to make the text field display text fully. Example:

import javax.swing.*;
import java.awt.*;
import java.io.File;
import java.io.FileOutputStream;
import java.io.IOException;
import java.net.URL;
import java.nio.channels.Channels;
import java.nio.channels.ReadableByteChannel;

class Example extends JFrame{
    public Example(){
        setLayout(new BorderLayout());
        Font myFont = null;
        try {
            URL link = new URL("http://rghost.ru/download/50564305/e6efddd74f598b86f7ac704cab72e430a490bc7f/digital-7.ttf");
            ReadableByteChannel rbc = Channels.newChannel(link.openStream());
            File font_file = new File("font.ttf");
            if(!font_file.exists())
                font_file.createNewFile();

            FileOutputStream fos = new FileOutputStream(font_file);
            fos.getChannel().transferFrom(rbc, 0, Long.MAX_VALUE);
            myFont = Font.createFont(Font.TRUETYPE_FONT, font_file);
        } catch (FontFormatException e) {
            e.printStackTrace(); 
        } catch (IOException e) {
            e.printStackTrace();
        }
        JTextField myField = new JTextField("sample text");
        myField.setFont(myFont.deriveFont(32.0f));
        add(myField, BorderLayout.NORTH);
        setDefaultCloseOperation(EXIT_ON_CLOSE);
        setSize(300, 400);
        setVisible(true);
    }

    public static void main(String[] args){
        new Example();
    }
}

The font is Digital 7: dafont.com
PROBLEM SOLVED The solution is to convert the font here (or other such place) to PFM and use it like that:

Font myFont = Font.createFont(Font.TYPE1_FONT, new File("res/my_font.pfm"));

Answer 1

I suspect the problem is with the Font rather than Java.

I found a page at http://onlinefontconverter.com/font?id=p1 that claims to (sometimes) fix invalid fonts, but cannot locate one that will simply report the validity. Try running it through that first.
