webp decode issue

[ssbroad]

The webp decoding package has a color conversion issue, which will affect the contrast of black-and-white images. It is recommended to use another package or switch to using dwebp for decoding.

cmd := exec.Command("dwebp.exe", "-o", "-", "--", "-") cmd.Stdin = bytes.NewReader(rawData)
cmd.Stderr = os.Stderr output, _ := cmd.Output() img, err := png.Decode(bytes.NewReader(output))

I find one, but the render seems pretty good. I don't see the problem. Is it happening in certains cases ?
