IMcImageSetInitialSignature Method

Sub SetInitialSignature ( 
	<OptionalAttribute> newVal As Object
)

The initial image signature represents the image data at the time of creation or capture. It can be set only once. To set the initial signature to "unknown" (e.g. if opening an image from a file format that does not support our signature), pass in an empty string. To set the initial signature to the current signature of the image, request the CurrentSignature and pass it in. If SetInitialSignature is passed a valid signature, then the CurrentSignature is also set to this value.
