Package enhance is a Go implementation for enhancing photographs (adjusting brightness, contrast, etc.)
This project aims to reproduce https://github.com/yuki-koyama/enhancer.
package main
import (
"image"
"image/jpeg"
"log"
"os"
"changkun.de/x/enhance"
)
func main() {
f, err := os.Open("testdata/1.jpg")
if err != nil {
log.Fatal(err)
}
defer f.Close()
img, err := jpeg.Decode(f)
if err != nil {
log.Fatal(err)
}
enhanced := enhance.Image(img, enhance.Params{
Brightness: .5,
Contrast: .5,
Saturation: .5,
Temperature: .5,
Tint: .5,
})
f, err = os.Create("testdata/enhanced.jpg")
if err != nil {
log.Fatal(err)
}
defer f.Close()
if err := jpeg.Encode(f, enhanced, nil); err != nil {
log.Fatal(err)
}
}
