java.awt.font 字母间距

Question

使用 java.awt.font 时是否可以增加字母间距？像这样:

Font font = new Font("serif", Font.PLAIN, 21);
//Increase the spacing - perhaps with deriveFont()?

BufferedImage image = new BufferedImage(400, 600, BufferedImage.TYPE_INT_RGB);
Graphics2D graphics = image.createGraphics();
graphics.setFont(font);
graphics.drawString("testing",0,0);

Answer 1

您可以派生一种新字体，具有更新的跟踪属性:

Map<TextAttribute, Object> attributes = new HashMap<TextAttribute, Object>();
attributes.put(TextAttribute.TRACKING, 0.5);
Font font2 = font.deriveFont(attributes);
gr.setFont(font2);
gr.drawString("testing",0,20);
