Overview

Package exif reads the EXIF metadata block out of a JPEG.

Parse walks the JPEG markers to the EXIF segment and decodes its TIFF structure into a TagStore, which preserves the order tags were found in and keeps the first value seen for a repeated tag. The parser matches the npm exif-parser library, including its use of exceptions for control flow, mirrored here as a scoped panic/recover that Parse converts to an error.

Functions

func ValueString 

func ValueString(v any) string

ValueString renders a simplified tag value the way JS string interpolation does (numbers via JS Number formatting, arrays joined by ",").

Types

type TagStore 

type TagStore struct {
	Order []string
	// contains filtered or unexported fields
}

TagStore preserves tag insertion order with first-value-wins semantics.

func Parse 

func Parse(data []byte) (store *TagStore, err error)

Parse parses all EXIF tags from a JPEG/TIFF byte stream.

func (*TagStore) Get 

func (s *TagStore) Get(name string) (any, bool)

Get returns the value stored under name, and whether it is present.
