Question: what is a ascale line?

Hi 10mldef again, how are you?
I haven’t heard of an ascale line, but if you mean a scale line, this is something that forensic scientists put in all their photographs of evidence, to show what size it is. If a scale line of a known scale (like cm or mm) is included in the pciture, then everybody can compare the evidence in the picture to the known scale and immediately see what size it is, and whether the picture has been magnified or distorted in any way.

Is this what you meant? If not, please ask again! 🙂
