纯 Go 实现的多种图像处理算法库。示例代码： ```go package main import ( "github.com/anthonynsimon/bild/effect" "github.com/anthonynsimon/bild/imgio" "github.com/anthonynsimon/bild/transform" ) func main() { img, err := imgio.Open("input.jpg") if err != nil { fmt.Println(err) return } inverted := effect.Invert(img) resized := transform.Resize(inverted, 800, 800, transform.Linear) rotated := transform.Rotate(resized, 45, nil) if err := imgio.Save("output.png", rotated, imgio.PNGEncoder()); err != nil { fmt.Println(err) return } } ```
