尝试存储到图像。 bt是字节数组
InputStream is = new ByteArrayInputStream(bt);
Image img = ImageIO.read(is);
ImageIO.write(img,"jpg",new File("C:\\home_loan.jpg") );
,请帮帮我,
错误 - :找不到符号
symbol:方法write(java.awt.Image,java.lang.String,java.io.File)
location:class javax.imageio.ImageIO
ImageIO.write(img,“jpg”,new File(“C:\ home_loan.jpg”));

使用BufferedImage。这是一个由内存支持的Image,有两个setRGB
方法。
按此定制您的数据;否则你需要转换数据结构,在一个BufferedImage上工作。

您可以使用以下方法 -
/**
* @param path full path of image
* @return image file for supplied path
*/
private BufferedImage getImage(String path) {
BufferedImage image = null;
File file = new File(path);
try {
image = ImageIO.read(file);
} catch(Exception e) {
e.printStackTrace();
}
return image;
}
/**
* @param userSpaceImage
* @return byte array of supplied image
*/
private byte[] getByteData(BufferedImage userSpaceImage) {
WritableRaster raster = userSpaceImage.getRaster();
DataBufferByte buffer = (DataBufferByte) raster.getDataBuffer();
return buffer.getData();
}
/**
* @param image image-file to save
* @param file to save image to
* @param extension of image file
* @return full path of saved image
*/
private String saveImage(BufferedImage image, File file, String extension) {
try {
ImageIO.write(image, extension, file);
} catch(Exception e) {
e.printStackTrace();
}
return file.getAbsolutePath();
}
