nifuda
nifuda provides a native Go library to read tags from EXIF image files.
Getting Started
As a example, a very simplistic EXIF reader:
package main
import (
"fmt"
"log"
"os"
"reflect"
"github.com/vinymeuh/nifuda"
)
func main() {
if len(os.Args) != 2 {
log.Fatalf("Usage: %s EXIF_FILE", os.Args[0])
}
f, err := os.Open(os.Args[1])
if err != nil {
log.Fatal(err)
}
defer f.Close()
x, err := nifuda.Read(f)
if err != nil {
log.Fatal(err)
}
v := reflect.ValueOf(x.Image)
vt := v.Type()
for i := 0; i < vt.NumField(); i++ {
fmt.Printf("Image.%-30s %v\n", vt.Field(i).Name, v.Field(i).Interface())
}
v = reflect.ValueOf(x.Photo)
vt = v.Type()
for i := 0; i < vt.NumField(); i++ {
fmt.Printf("Photo.%-30s %v\n", vt.Field(i).Name, v.Field(i).Interface())
}
}More examples are availables in nf-tools repository.
