HEIC Images

[techtron79]

As before, I am running picframe on a Pi 3. I made the library changes described at https://www.thedigitalpictureframe.com to enable HEIC images. The changes worked and picframe does display the images. However, there are a couple of issues:

1. I get the following warning for each of the HEIC images during initialization:
   WARNING:get_image_meta.GetImageMeta:get_size failed on /home/pi/Pictures/test3.HEIC -> cannot identify image file '/home/pi/Pictures/test3.HEIC'
   As I said, the images display, so perhaps I should just ignore this warning? As info, when I inspect the picframe database, the height and width values for the HEIC images are 0.
2. Portrait/landscape determination does not seem to work for HEIC. A sample image is attached. picframe displays it as landscape, but other programs display it properly as portrait.

Not sure anything can be done about these issues since they may caused by the underlying libraries, but I just wanted to pass them on. Thanks for any help.

We need to keep an eye on the HEIC stuff - it's quite fast changing at the moment so modules etc will probably be gradually catching up. The one we used exifread seems to have some issues with HEIC files and hasn't been updated since April, maybe time to look around?

Good point. But what are the alternatives for exifread. I like exiftool but although there is a python wrapper available you have to install it separately. We could move back to PIL.ExifTags? Have to play around with it.

Looks like pyheif (which we're already using) might support at least some of what we want from HEIF images. Though, we'd have to handle them independently in that case I guess...

I fixed this on dev. Will be part of the next release.

Great - thank you!
