pyexiftool is just a wrapper for exiftool. exiftool looks great, but for my use case, I only need to strip all metadata. It would be much easier if that was in pure Python and pure Java. perl is a no go on Android.
It was dead simple to strip EXIF from JPEG in Python: from pil import Image with open(inpath) as fp: in_image = Image.open(fp) data = list(in_image.getdata()) out_image = Image.new(in_image.mode, in_image.size) out_image.putdata(data) out_image.save(outpath) But that broke some PNGs, and the rest were larger in size. .hc Rick Valenzuela: > oh, you may already know this, but the previous code keeps a copy of the > file and metadata. if you want it gone with no copies, you have to add a > switch to overwrite, e.g.: > > ``` > with exiftool.ExifTool() as et: > et.execute(b'-all=', b'-overwrite_original', b'some.png') > ``` > > On 12/12/2017 23:45, Rick Valenzuela wrote: >> heh, nice -- I just found this: >> >> https://github.com/smarnach/pyexiftool >> >> Tried it out and it worked great: >> ``` >> with exiftool.ExifTool() as et: >> et.execute(b'-all=', b'some.png') >> ``` >> >> On 12/12/2017 19:53, Hans-Christoph Steiner wrote: >>> >>> Ah, cool, I thought exiftool only worked with JPEGs.
