读取并修改照片信息

背景不过多介绍，就是想获取并修改照片中的拍摄时间、经纬度等信息，并且当在windows环境下，图片会有标题、主题、描述等属性，如果可以，希望能够一并获取。

可能是需求比较奇怪，这方面的内容在国内很少，最终发现org.apache.commons-imaging包可以解决这个问题。

1.引入依赖

gradle:

implementation 'org.apache.commons:commons-imaging:1.0-alpha1'


maven:


org.apache.commons
commons-imaging
1.0-alpha1



2.代码举例

public void buildPhoto(File file) throws IOException, ImageReadException, ImageWriteException {
ImageMetadata imageMetadata = Imaging.getMetadata(file);
JpegImageMetadata metadata = (JpegImageMetadata) imageMetadata;
//遍历所有图片属性
for (ImageMetadata.ImageMetadataItem item : metadata.getItems()) {
System.out.println(item);
}
//获取标题属性的值
if (metadata.findEXIFValue(MicrosoftTagConstants.EXIF_TAG_XPTITLE) != null) {
Object titleValue = metadata.findEXIFValue(MicrosoftTagConstants.EXIF_TAG_XPTITLE).getValue();
System.out.println(titleValue);
}
//获取经纬度信息
TiffImageMetadata exif = metadata.getExif();
if (exif != null && exif.getGPS() != null) {
TiffImageMetadata.GPSInfo gpsInfo = exif.getGPS();
double lOngitudeAsDegreesEast= gpsInfo.getLongitudeAsDegreesEast();
double latitudeAsDegreesNorth = gpsInfo.getLatitudeAsDegreesNorth();
}
//修改某个属性值
TiffOutputSet out = exif.getOutputSet();
//获取TiffOutputDirectory
TiffOutputDirectory exifDirectory = out.getOrCreateExifDirectory();
//拍摄日期修改 注意日期格式为 yyyy:MM:dd HH:mm:ss
exifDirectory.removeField(ExifTagConstants.EXIF_TAG_DATE_TIME_ORIGINAL);
exifDirectory.removeField(ExifTagConstants.EXIF_TAG_DATE_TIME_DIGITIZED);
exifDirectory.add(ExifTagConstants.EXIF_TAG_DATE_TIME_ORIGINAL, "2022:01:01 00:00:00");
exifDirectory.add(ExifTagConstants.EXIF_TAG_DATE_TIME_DIGITIZED, "2022:01:01 00:00:00");

//gps信息修改
out.setGPSInDegrees(116.23128, 40.22077);
BufferedOutputStream bos = new BufferedOutputStream(new FileOutputStream("path"));
//写图片
new ExifRewriter().updateExifMetadataLossless(file, bos, out);
}
