Java简单获取字符串像素的方法

Graphics2D g = (Graphics2D)Toolkit.getDefaultToolkit().
 getImage("imgname").getGraphics();
// 设置大字体
Font font = new Font("楷体", Font.ITALIC | Font.BOLD, 72);
g.setFont(font);
FontRenderContext context = g.getFontRenderContext();
// 获取字体的像素范围对象  
Rectangle2D stringBounds = font.getStringBounds("text", context);
double fontWidth = stringBounds.getWidth();
