The GoDoc incorrectly specified that the LoadImageHash function produces an ExtImageHash. This function produces an ImageHash, so this corrects the typo.
Create a new APIs for serializing purpose which can use
standard io.Reader/io.Writer APIs.
ToString() API will be remain for debugging purpose and
ExtImageHashFromString, ImageHashFromString will be removed after next
version.
- New APIs are added: LoadExtImageHash, LoadImageHash, xxxHash.Dump
- These APIs are deprecated: ExtImageHashFromString, ImageHashFromString
The ToString and FromString methods create a string representation
of an ImageHash, following the format:
`<first letter of type>:<hex representation of hash`
