综上所述,我们的Java代码整合如下: importjava.util.Base64;importjava.io.FileOutputStream;importjava.io.IOException;publicclassBase64Example{publicstaticvoidmain(String[]args){Stringbase64String="data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAUA...";// 第1步:解码Base64字符串byte[]decodedBytes=B...
The second is to allow you to create a custom image using a HTML5 Canvas and then export it as a data URL. This example takes the following base64 string of an image and uses it to create a custom pushpin in the center of the map....
// 将图片转换为base64格式byte[]bytes=pictures.get(0).getData();Stringbase64Image=Base64.getEncoder().encodeToString(bytes); 1. 2. 3. 步骤4:导出base64格式的图片 最后,我们将base64格式的图片导出到一个文件中。下面是导出base64格式的图片的代码: // 将base64格式的图片写入文件try(PrintWriterwrite...

可以使用JavaScript中的Image对象来创建一个图像对象。 代码语言:txt 复制 var img = new Image(); img.src = 'data:image/png;base64,base64_string'; 在上述代码中,base64_string是你要转换的base64编码的字符串。这里的data:image/png;base64,是图像的数据格式和编码方式,可以根据实际情况进行修改,比如...
base64String = encoder.encodeToString(bytes); }catch(Exception e) { e.printStackTrace(); }returnbase64String; } } 接下来写接口,创建一个ValidateCodeController.java, 先是生成验证码,返回图片的接口: importcom.example.demo.util.ValidateCodeUtil;importorg.springframework.web.bind.annotation.GetMapping;im...
In the following example, we useBase64.getEncoder().encode()to read the image data into base64 encoded byte array. We can convert this byte array to string for storing or transferring over the network. Later, we can use the encoded byte array or string to restore back into image, when...
