func Image

func Image(ctx context.Context, policyContext *signature.PolicyContext, destRef, srcRef types.ImageReference, options *Options) (manifest []byte, retErr error)

Image copies image from srcRef to destRef, using policyContext to validate source image admissibility. It returns the manifest which was written to the new copy of the image.

	ReportWriter     io.Writer
	SourceCtx        *types.SystemContext
	DestinationCtx   *types.SystemContext
	ProgressInterval time.Duration                 // time to wait between reports to signal the progress channel
