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();
