#How to grep exif data from imagemagic display how to#

I came across this helpful article which outlines how to view exif information from the command line using the identify command. I like to use touch in conjunction with jhead to set exif picture taken times for files that don’t have any metadata but I know the date they were taken: jhead -mkexif *.jpgįor pictures which have correct metadata but incorrect modified date (downloaded pictures, for example) simply do the following: jhead -ft *.jpg To create metadata for all JPG files in a current directory: jhead -mkexif *.JPG You can use wildcards, which is super convenient.

– dsft Set the EXIF date taken date of the picture to match the modified time of the filesystem for that picture.

-ft Set picture’s filesystem modified date to match the EXIF date taken contained in the picture.

– mkexif Create EXIF data for a picture that does not contain it.

It has many options, but the ones I use most frequently are the following:

I’ve discovered that jhead is a wonderful tool to accomplish this. Overall, the experience left me dissappointed and dissatisfied with PIL.From time to time I find I need to edit the date taken metadata on pictures. tiff) file from the command line in Debian Linux or most other Linux variants here’s how. If you want to make use of the EXIF data stored in a JPEG (.jpg or.

Meanwhile, as I was getting tired of coaxing PIL to do what I want, I just wrote a a little bash script to do the same in imagemagick. Googling around didn’t turn up any intersting solutions – so if any of you have any ideas, please share. I also tried the exiv2 library, but couldnt figure out a way to load the image, annotate it and then copy over the metadata. Unfortunately, PIL has a fatal flaw – you can annotate the image and save it – but then the saved image doesn’t retain the original image’s exif metadata. Outfile = join(dirname(file), 'Ann_' + basename(file)) # the image, the exif data is'nt preserved.įormat='%(asctime)s %(levelname)s %(message)s')ĭt = datetime.datetime (*time.strptime (ret,'%Y:%m:%d %H:%M:%S'))įont = uetype('/usr/share/fonts/truetype/ttf-dejavu/DejaVuSans-Bold.ttf', 36)ĭraw.text((width * 0.7, height - 100),exif.strftime('%a %d-%b-%Y %l:%M %p'), font=font, fill='orange')

# Important: I set out to write the image annotation in PIL - there's one serious drawback though. Here’s my PIL effort – functional, but one that came with quite some amount of googling and trying to make sense of the PIL documentation which is inadequate at best.įrom os.path import basename, dirname,join I knew imagemagick would do the trick, but thought it would be a good time to play around with PIL and python. Many digicams have an option to do this – unfortunately, my Panasonic DMC-LZ8 doesn’t seem to do this.

Decided that I want to timestamp my photo collection with the date from the exif data.
