# mirror
It's a very simple package with only one function for mirror image.
Function `MirrorImage` get 3 parameters:
```
func MirrorImage(in image.Image, ox bool, oy bool) image.Image
```
- `in` - object for mirror
- `ox` - if `true` when image mirrored horizontally
- `oy` - if `true` when image mirrored vertically
## Simple usage
First get the package:
```
$ go get github.com/janczer/mirror
```
After that create `main.go` and add this:
```
package main
import (
"fmt"
"github.com/janczer/mirror"
"image"
"image/jpeg"
"log"
"os"
)
func main() {
fmt.Println("simple usage github.com/janczer/mirror")
reader, err := os.Open("test.jpg") //open image file
if err != nil {
log.Fatal(err)
}
defer reader.Close()
m, _, err := image.Decode(reader) //decode file
if err != nil {
log.Fatal(err)
}
mirroredImage := mirror.MirrorImage(m, true, true)
//create new image file
f, err := os.Create("mirror.jpg")
jpeg.Encode(f, mirroredImage, nil)
f.Close()
}
```
Save image that you want mirrored to the same directory that `main.go` and run it:
```
$ go run main.go
```
And you have two files `test.jpg` and `mirror.jpg`.
