如何使用golang压缩和调整gif大小

Question

Is there has method or lib to compress and resize a gif use golang?

ps: I was tried bimg, but it not support gif.

Answer 1

see doc https://golang.org/pkg/image/gif/#GIF

func DecodeAll(r io.Reader) (*GIF, error)

now you can get a GIT struct

type GIF struct {
        Image []*image.Paletted // The successive images.

then you can resize each of Image in GIF.

for _,img:=range gif.Image{
    resize(img)
}

PS: image.Paletted implemented image.Image. so you can use https://github.com/nfnt/resize to do your job.
