here i'd like to share some codes with you to help you create EAN-8 in project.
Dim reImage As REImage = REFile.OpenImageFile("c:/Sample.png", New PNGDecoder()) Dim barcode As New Linear() 'create a barcode
barcode.Type = BarcodeType.EAN8 'select barcode type
barcode.Data = "7777777" 'Enter a 7-digit data string
barcode.X = 1F 'set bar width
barcode.Y = 60F 'set bar height
barcode.Resolution = 96 'set resolution
barcode.Rotate = Rotate.Rotate0 'set rotate
barcode.DrawBarcode(reImage, 0, 0) 'draw barcode on REImage with location x and y
REFile.SaveImageFile(reImage, "c:/ean8.png", New PNGEncoder())
