- create go.mod (deleted upstream at v1.0.3) with module github.com/hanzoai/goexif, go 1.21 - rewrite all internal self-imports (exif/tiff/mknote/exifstat/tests/regen) to hanzoai path - update README import-path/install references - pure stdlib, zero external deps; go build/vet/test all pass
goexif
Provides decoding of basic exif and tiff encoded data. Still in alpha - no guarantees. Suggestions and pull requests are welcome. Functionality is split into two packages - "exif" and "tiff" The exif package depends on the tiff package.
Like goexif? - Bitcoin Cash tips welcome: 1DrU5V37nTXuv4vnRLVpahJEjhdATNgoBh
To install, in a terminal type:
go get github.com/hanzoai/goexif/exif
Or if you just want the tiff package:
go get github.com/hanzoai/goexif/tiff
Example usage:
package main
import (
"fmt"
"log"
"os"
"github.com/hanzoai/goexif/exif"
"github.com/hanzoai/goexif/mknote"
)
func ExampleDecode() {
fname := "sample1.jpg"
f, err := os.Open(fname)
if err != nil {
log.Fatal(err)
}
// Optionally register camera makenote data parsing - currently Nikon and
// Canon are supported.
exif.RegisterParsers(mknote.All...)
x, err := exif.Decode(f)
if err != nil {
log.Fatal(err)
}
camModel, _ := x.Get(exif.Model) // normally, don't ignore errors!
fmt.Println(camModel.StringVal())
focal, _ := x.Get(exif.FocalLength)
numer, denom, _ := focal.Rat2(0) // retrieve first (only) rat. value
fmt.Printf("%v/%v", numer, denom)
// Two convenience functions exist for date/time taken and GPS coords:
tm, _ := x.DateTime()
fmt.Println("Taken: ", tm)
lat, long, _ := x.LatLong()
fmt.Println("lat, long: ", lat, ", ", long)
}
