Support IOS11 HEIF format

At the moment HEIF format is not supported

@payton, you said you looked at this a while back. Is there anything you can point to?

https://en.wikipedia.org/wiki/High_Efficiency_Image_File_Format

At the time that I was looking through it, I was having some issues finding enough documentation on it, but the MPEG site provided some helpful documentation https://mpeg.chiariglione.org/standards/mpeg-h
The website/documentation isn't the easiest to navigate through.

https://mpeg.chiariglione.org/standards/mpeg-h/image-file-format

I'll do some more digging for better documentation now that it has seen more light in iOS11

This seems to be a good paper on HEIF from the Tampere University of Technology (Finland) https://dspace.cc.tut.fi/dpub/bitstream/handle/123456789/24147/heikkila.pdf
I will try to get through more of it later today when I travel.

My earlier implementation was simple, but did at least pull out the width/height and some other lesser values. Looking through it now...

I think the ISO/IEC 23008-12 itself should have all the documentation you'd need 😉

@maczikasz If you have any sample HEIF images you could contribute to https://github.com/drewnoakes/metadata-extractor-images, that would help with continued development.

[payton]

Just to keep this issue updated, I am working on adding some of the image properties (as specified in ISO/IEC 23008-12:2017 in section 6.5).
https://github.com/payton/metadata-extractor/tree/heif-image-properties

Currently, I have added Image Rotation, Pixel Information, and Colour Information. These will extract image rotation (in degrees counter-clockwise), ICC Profile, and bits per channel (pixel depth). A PR will be made soon. These are the only properties I am able to test at the moment. We will be able to add more when we get sample images.

PR: #372

@payton In case you still need some image samples:

Hi. Great library Drew.

I wrote this class to integrate the Nokia HEIF reference implementation.

https://github.com/grizzly100/metamorphosis/blob/master/src/main/java/org/grizzlytech/metamorphosis/imaging/heif/HEIFMetadataReader.java

I only wanted “date taken”, but the sample shows your library nicely parses the bytes returned by the Nokia native library.

pure Java , based on metadata-extractor , support heic/heif

@zosatapo can you submit a pull request so that your work can be used by existing users of this library?

[zosatapo]

I have submitted a pull request  to extract EXIF metadata  for HEIF format , please verify it. 1.  change SequentialReader to RandomAccessReader  for reading  EXIF data buffer  from HEIF meta BOX 2.  modify HeifHandler to extract EXIF location with  ItemInfoBox  and ItemLocatonBox

hi @zosatapo thank you for your work! With your implementation it is possible to get heif thumbnail? Is it stored inside exif data?

this issue should be closed, 2.16.0 resolved it

@ahao140202 thank you!
