<AWT Dev> [OpenJDK 2D-Dev] [9] Review request for 8073320 Windows HiDPI Graphics support

I’m not sure it’s practical, but has anybody every thought about using existing EXIF tags to determine image resolution?

AFAIK, both JPEG and TIFF support EXIF tags (http://www.w3.org/2003/12/exif/) and thus embedding of resolution metadata (Labels: resolution, xResolution, yResolution, resolutionUnit).

There could be another special tag @exif (or @native, to avoid being tied down to one particular way of embedding info), which basically means: check the embedded resolution info.
