示例#1

文件： signature.go 项目： kitak/magick

// Signature computes a message digest from an image pixel stream with an
// implementation of the NIST SHA-256 Message Digest algorithm. This
// signature uniquely identifies the image and is convenient for determining
// if an image has been modified or whether two images are identical.
func (im *Image) Signature() uint {
	return uint(C.SignatureImage(im.image))
}
