我用以下示例代码创建了一个图形图像.
- BufferedImage bi = new BufferedImage(50,50,BufferedImage.TYPE_BYTE_BINARY);
- Graphics2D g2d = bi.createGraphics();
- // Draw graphics.
- g2d.dispose();
- // BufferedImage now has my image I want.
此时我有BufferedImage,我想将其转换为IMG数据URI.这可能吗？例如..
- <IMG SRC="data:image/png;base64,[BufferedImage data here]"/>
解决方法
没有测试,但这样的事情应该这样做：
- ByteArrayOutputStream out = new ByteArrayOutputStream();
- ImageIO.write(bi,"PNG",out);
- byte[] bytes = out.toByteArray();
- String base64bytes = Base64.encode(bytes);
- String src = "data:image/png;base64," + base64bytes;
有lots of different base64 codec implementations for Java.我在MigBase64取得了不错的成绩.
