Resize image in Python without losing EXIF data

Question

I need to resize jpg images with Python without losing the original image's EXIF data (metadata about date taken, camera model etc.). All google searches about python and images point to the PIL library which I'm currently using, but doesn't seem to be able to retain the metadata. The code I have so far (using PIL) is this:

img = Image.open('foo.jpg')
width,height = 800,600
if img.size[0] < img.size[1]:
    width,height = height,width

resized_img = img.resize((width, height), Image.ANTIALIAS) # best down-sizing filter
resized_img.save('foo-resized.jpg')

Any ideas? Or other libraries that I could be using?

Answer 1

import jpeg
jpeg.setExif(jpeg.getExif('foo.jpg'), 'foo-resized.jpg')

Answer 2

PIL handles EXIF data, doesn't it? Look in PIL.ExifTags.

Answer 3

Why not using ImageMagick?
It is quite a standard tool (for instance, it is the standard tool used by Gallery 2); I have never used it, however it has a python interface as well (or, you can also simply spawn the command) and most of all, should maintain EXIF information between all transformation.

Answer 4

You can use pyexiv2 to modify the file after saving it.
