ExifInterfaceImageHeaderParser

class ExifInterfaceImageHeaderParser : ImageHeaderParser
Content copied to clipboard

Uses ExifInterface to parse orientation data.

ExifInterface supports the HEIF format on OMR1+. Glide's DefaultImageHeaderParser doesn't currently support HEIF. In the future we should reconcile these two classes, but for now this is a simple way to ensure that HEIF files are oriented correctly on platforms where they're supported.

val UNKNOWN_ORIENTATION: Int

A constant indicating we were unable to parse the orientation from the image either because no exif segment containing orientation data existed, or because of an I/O error attempting to read the exif segment.
