Sure, if you donate a camera, I'll fully implement it. ;)
Seriously, there is a lot to do and we cannot add each extension that is
used by a single hardware model. But it's a damn cool feature.
Hopefully, there will be other vendors and models supporting this!
Don't tell anyone i touched java - I have something rudimentary working
which draws a little triangle arrow below the camera icon when activating it
e.g. clicking on the picture icon - It does only so when there is a
GPS Image Direction tag in the exif header. I had no clue about java but
someone might hint me through some design/style issues ... Especially
i think there is some overhead in the exception reading the exif tags as
this
+Metadata metadata =
JpegMetadataReader.readMetadata(e.getFile());
+Directory directory =
metadata.getDirectory(GpsDirectory.class);
is called twice ... Probably unnecessary
Here is a small screenshot how it will look:
