Go Binding for Imageflow

Quickly scale or modify images and optimize them for the web.

If the AGPLv3 does not work for you, you can get a commercial license on a sliding scale. If you have more than 1 server doing image processing your savings should cover the cost.

)

func main(){
	step:=imageflow.NewStep()
	data,_:=step
	.Decode(imageflow.NewURL("https://jpeg.org/images/jpeg2000-home.jpg"))
	.Branch(func(step *imageflow.Steps){
		step
		.ConstrainWithin(200,200)
		.Encode(imageflow.NewFile("test_1.jpg"),imageflow.MozJPEG{})
	}).ConstrainWithin(400,400)
	.Encode(imageflow.GetBuffer("test"),imageflow.MozJPEG{})
	.Execute()
	ioutil.WriteFile("test_2.jpeg",data["test"],0644)
