Assuming there is an official spec for 3-byte ASCII Signature Format, and that it is not vendor specific.
Spec required for converting between formats and rendering.

I've never even heard of a 3-byte ASCII Signature, much less seen an official spec for one. Where did you come across it? – Mark Ransom Dec 01 '16 at 19:58

I did a Google search on this and found an explanation for plotting on a 1024x1024 bitmap. So after reading that, I STILL have no idea what the question is. – durbnpoisn Dec 01 '16 at 20:00

@MarkRansom Customer signature capture from payment devices (pin and signature pads). – CrashCodes Dec 05 '16 at 15:56

I found the spec embedded in vendor documentation. I also saw someone post the spec in a c# forum: https://social.msdn.microsoft.com/forums/vstudio/en-US/1dc7421a-56dc-4698-ac33-9c79e25fde36/saving-series-of-point-data-in-c . I know of a different vendor that renders signatures that are in this format, but I still don't know if this proprietary or an open standard perhaps with a different name? – CrashCodes Aug 13 '18 at 19:53
