![]() ![]() Now we can work with it through the console. With this we will have the program installed. ![]() We just have to open a terminal (Ctrl Alt T) and execute the following command: EXIFTOOL OPTIONS INSTALLWe can install ExifTool in Ubuntu in a simple way. So we will also have to be careful about the files we share because they can carry information that we do not want to share. As you can appreciate metadata isn't just for images, but can be applied to all types of files.Īlthough these details can be very useful to classify any type of file, they also may contain sensitive information. ĮxifTool supports many different metadata formats including EXIF, GPS, IPTC, XMP, JFIF, GeoTIFF, ICC Profile, Photoshop IRB, FlashPix, AFCP, and ID3, as well as digital camera image metadata. The information that is housed in the metadata can be of any type, from the name of the company, to the name of the computer, through tags, modification dates, location, etc. These types of image metadata can be in various formats. Such as the camera with which a photograph was taken or the time it was taken. The metadata of the photographs is extra data that is added to the files. It is available as a Perl library and a command line application. It is independent of the platform we use. EXIFTOOL OPTIONS PDFThis is a free and open source program for reading, writing and manipulating image, audio, video and PDF metadata. In the next article we are going to take a look at ExifTool. directory find and execute on every document found. Print(json.dumps(tadata_lookup, indent=3)) ![]() tadata_lookup = self.get_metadata(FileLoc) ![]() Return json.loads(self.execute("-G", "-j", "-n", *FileLoc))įor dirname, dirnames, filenames in os.walk(locDir): > 30 (str.join("\n", args))ĪttributeError: 'ExifTool' object has no attribute 'process' return follow ERROR using Python 3.8.10 and IPYTHON Otherwise the program will hang because the while loop inside execute() won't stop EXIFTOOL OPTIONS SERIESThe second is that you have to decode the byte series returned by os.read(): output = os.read(fd, 4096).decode('utf-8')ĮDIT for Windows: To get this working on Windows, the sentinel need to be changed into "\r\n" The first is an additional argument to subprocess.Popen: self.process = subprocess.Popen( To get this to work in python 3 two small changes are needed. This class is written as a context manager to ensure the process is exited if you are done. Return json.loads(self.execute("-G", "-j", "-n", *filenames)) Stdin=subprocess.PIPE, stdout=subprocess.PIPE)ĭef _exit_(self, exc_type, exc_value, traceback): I also included get_metadata() to read the metadata in JSON format: import subprocessĭef _init_(self, executable="/usr/bin/exiftool"): Here's a simple class that launches an exiftool process and features an execute() method to send commands to that process. ExifTool supports JSON output, which is probably the best option for reading the metadata. You can then send commands to the process via stdin, and read the output on stdout. To avoid launching a new process for each image, you should start exiftool using the -stay_open flag. ![]()
