#Remarks
You can call this class function and pass a stream as the AStream parameter to identify if the stream contains a GIF image that starts from its current position. The class function returns True if the ‘GIF87a’ or ‘GIF89a’ header is located at the current stream position; otherwise, False. These headers (that is, “magic numbers” or file signatures interpreted as ASCII characters) indicate the supported GIF 87a (original) and 89a (enhanced) image format standards.
