ImageGear processes EXIF as a metadata format, rather than as a separate image file format.
EXIF level metadata uses the following structure.
| Name | Id | Type | Value Type | Value | Value Length | Ignored on save |
| <EXIF subIFD tags> | <EXIF subIFD tag ids> | |||||
| "Interoperability" | ImGearMetadataFormats.INTEROPERABILITYIFD | Tree | ||||
| "GPS" | ImGearMetadataFormats.INTEROPERABILITYIFD | Tree |
Interoperability and GPS IFDs are optional.
See Exif subIFD tags below for the list of Exif subIFD tag names and Ids.
EXIF GPS level metadata uses the following structure:
| Name | Id | Type | Value Type | Value | Value Length | Ignored on save |
| <EXIF GPS tags> | <EXIF GPS tag ids> |
See GPS subIFD tags below for the list of EXIF GPS tag names and Ids.
EXIF Interoperability level metadata uses the following structure:
| Name | Id | Type | Value Type | Value | Value Length | Ignored on save |
| <EXIF Interoperability tags> | <EXIF Interoperability tag ids> |
See Interoperability subIFD tags below for the list of EXIF Interoperability tag names and Ids.
