PNG support? #28

Closed alifeinbinary closed 7 years ago

alifeinbinary commented 7 years ago

What's the likelihood that piexifjs could support png? Any plans for implementing this in the future? Thanks for all the hard work, it's a really great library :)

hMatoba commented 7 years ago

No. PNG images don't have exif.

@hMatoba Because PNG doesn't have exif, is there any other solution?

hkung77 commented 5 years ago

Perhaps this can be revisited since it seems like there is EXIF chunk on Png files

As this repository is not supported anymore, I added png and webp support to this fork. https://github.com/asc0910/exif-library
