Lists all EXIF MakerNote types.
Values:
| IG_MAKERNOTE_TYPE_UNKNOWN | Unknown. This is the default type. This type means that ImageGear can't detect Makernote as any other type. Preserving such a makernote and saving it with the file, most likely, does not make any sense, because IFD offsets will be corrupted. |
| IG_MAKERNOTE_TYPE_IFD | TIFF IFD. Makernote is a valid TIF IFD. |
| IG_MAKERNOTE_TYPE_IFD_PREFIXED | Prefixed TIFF IFD. Same as IFD, but with a short prefix before the IFD. The prefix is also preserved, so the whole Makernote is preserved when writing to a file. |
| IG_MAKERNOTE_TYPE_TIF_HEADER_PREFIXED | Makernote starts with a prefix, then goes TIF image header, which points to an IFD. |
| IG_MAKERNOTE_TYPE_IFD_PREFIXED_OFFSET_II | Makernote starts with a prefix, then goes offset to the IFD, then IFD itself. Makernote IFD uses Intel byte ordering (II), even though the whole file uses Motorola ordering. |
| IG_MAKERNOTE_TYPES_MAX | Specifies the number of supported makernote types. |
