    Hi everyone!

    In my project I need to read Exif info from JPG and PNG images. I tryed to use method text() from QImageReader but this method doesn't read all informations. Also I've found the QExifImageHeader This library is also can read Exif info for JPG but not PNG. Could you tell me how I can read all Exif info and tags from images?

    P.S. libexif and exiv2 I can use in my project if I will not find any other solutions.

      Hi,

      AFAIK, PNG doesn't contain the same meta data so you won't be able to use QExifImageHader to read them.
