[Help]Can it compress a tif image of 1GB?

[Ted-bug]

I want to compress a tif image of 1GB or more, but it always returns unknown format .But it can successfully compress 700MB tif image.

f := "E:\\workPlace\\sys-tool\\example\\baidu\\V24080165.tif"
fs, err := os.Open(f)
if err != nil {
fmt.Println(err)
return
}
img, err := imaging.Decode(fs)
if err != nil {
fmt.Println(err)
return
}
fmt.Println(img.Bounds().Dx())

My tif image's magic is II+.This is different with default format(II* or MM*).
