| void exif_content_add_entry | ( | ExifContent * | c, | |
| ExifEntry * | entry | |||
| ) |
Add an EXIF tag to an IFD.
If this tag already exists in the IFD, this function does nothing.

| void exif_content_fix | ( | ExifContent * | c | ) |
Fix the IFD to bring it into specification.
Call exif_entry_fix on each entry in this IFD to fix existing entries, create any new entries that are mandatory in this IFD but do not yet exist, and remove any entries that are not allowed in this IFD.
