This project is concerned only with parsing and encoding raw EXIF data. It does not understand specific file-formats. This package assumes you know how to extract the raw EXIF data from a file, such as a JPEG, and, if you want to update it, know how to write it back. File-specific formats are not the concern of *go-exif*, though we provide [exif.SearchAndExtractExif](https://godoc.org/github.com/dsoprea/go-exif/v2#SearchAndExtractExif) and [exif.SearchFileAndExtractExif](https://godoc.org/github.com/dsoprea/go-exif/v2#SearchFileAndExtractExif) as brute-force search mechanisms that will help you explore the EXIF information for newer formats that you might not yet have any way to parse.
That said, the author also provides [go-jpeg-image-structure](https://github.com/dsoprea/go-jpeg-image-structure) and [go-png-image-structure](https://github.com/dsoprea/go-png-image-structure) to support properly reading and writing JPEG and PNG images. See the [SetExif example in go-jpeg-image-structure](https://godoc.org/github.com/dsoprea/go-jpeg-image-structure#example-SegmentList-SetExif) for practical information on getting started with JPEG files.
That said, the author also provides the following projects to support the efficient processing of the corresponding image formats:
- [go-jpeg-image-structure](https://github.com/dsoprea/go-jpeg-image-structure)
- [go-png-image-structure](https://github.com/dsoprea/go-png-image-structure)
- [go-tiff-image-structure](https://github.com/dsoprea/go-tiff-image-structure)
- [go-heic-exif-extractor](https://github.com/dsoprea/go-heic-exif-extractor)
See the [SetExif example in go-jpeg-image-structure](https://godoc.org/github.com/dsoprea/go-jpeg-image-structure#example-SegmentList-SetExif) for practical information on getting started with JPEG files.
