Graphics2D 图片上绘制文字，并设置文字边框

代码实例

        // 读取原图片信息
        //得到文件
        File file = new File("d:\\1.png");
        //文件转化为图片
        Image srcImg = ImageIO.read(file);
        //获取图片的宽
        int srcImgWidth = srcImg.getWidth(null);
        //获取图片的高
        int srcImgHeight = srcImg.getHeight(null);
 
        BufferedImage bufImg = new BufferedImage(srcImgWidth, srcImgHeight, BufferedImage.TYPE_INT_RGB);
        Graphics2D g2 = bufImg.createGraphics();
g2.setRenderingHint(RenderingHints.KEY_ANTIALIASING,RenderingHints.VALUE_ANTIALIAS_ON);
g2.setRenderingHint(RenderingHints.KEY_ANTIALIASING, RenderingHints.VALUE_ANTIALIAS_ON);
g2.setRenderingHint(RenderingHints.KEY_STROKE_CONTROL, RenderingHints.VALUE_STROKE_PURE);
g2.setRenderingHint(RenderingHints.KEY_COLOR_RENDERING, RenderingHints.VALUE_COLOR_RENDER_QUALITY);
FontRenderContext frc = g2.getFontRenderContext();
TextLayout tl = new TextLayout("你好", new Font("黑体", Font.BOLD, 25), frc);
                    //文字所在位置
                    Shape sha = tl.getOutline(AffineTransform.getTranslateInstance(690,390));
                    g2.setStroke(new BasicStroke(3.0f));
                    //边框颜色
                    g2.setColor(new Color(178, 113, 23));
                    g2.draw(sha);
                    //字体颜色
                    g2.setColor(Color.WHITE);
                    g2.fill(sha);
                    g2.dispose();
 
ByteArrayOutputStream bs = new ByteArrayOutputStream();
        ImageOutputStream imOut = ImageIO.createImageOutputStream(bs);
        ImageIO.write(bufImg, "png", imOut);
        InputStream inputStream = new ByteArrayInputStream(bs.toByteArray());
        OutputStream outStream = new FileOutputStream("d:\\3.png");
        IOUtils.copy(inputStream, outStream);
        inputStream.close();
        outStream.close();
