The EXIF-TIFF metadata structure is similar to TIFF's one. But EXIF-TIFF allows Exif subIFD tags, GPS subIFD tags and thumbnail IFD tags to be parsed and passed together with main IFD.
| Name | Id | Type | Value Type | Value | Value Length | Read Only |
|---|---|---|---|---|---|---|
| "EXIF" | IG_FORMAT_EXIF_TIFF | LEVEL_START | 0 | NULL | 0 | True |
| "TIF_HEADER" | 59936 | VALUE_ITEM | UINT16 | 0x4949 or 0x4D4D | 1 | True |
| IFD 0 level ( if present) | ||||||
| Thumbnail IFD level ( if present) | ||||||
| "EXIF" | IG_FORMAT_EXIF_TIFF | LEVEL_END | 0 | NULL | 0 | True |
All items between items with Name "EXIF" and Id IG_FORMAT_EXIF_TIFF (Type LEVEL_START and LEVEL_END) are interpreted as EXIF data. If during sending data from application level to filter level the first item is omitted the data will not be interpreted and saved.
