[Golang] Read JPEG Image Date via Exif Metadata
March 16, 2016
Read JPEG image date from Exif metadata in Golang.
We use goexif package to read Exif metadata. Install it by:
$ go get -u github.com/rwcarlsen/goexif/exif
Source code:
date.go | repository | view raw
package jpgdate
import (
"fmt"
"github.com/rwcarlsen/goexif/exif"
"io/ioutil"
"os"
"path"
)
func ReadJpegDate(dirname string) {
files, err := ioutil.ReadDir(dirname)
if err != nil {
panic(err)
}
for _, file := range files {
fpath := path.Join(dirname, file.Name())
println(fpath)
f, err := os.Open(fpath)
if err != nil {
panic(err)
}
defer f.Close()
x, err := exif.Decode(f)
if err != nil {
panic(err)
}
tm, _ := x.DateTime()
fmt.Println(tm.Date())
}
}
date_test.go | repository | view raw
package jpgdate
import "testing"
func TestReadJpegDate(t *testing.T) {
ReadJpegDate("/home/foo/Desktop/Photos/")
}
Tested on: Ubuntu Linux 15.10, Go 1.6.
