The script to convert stanford form touch-coordinates to business cards on pdf is complete.

Summary of steps:

1. convert touch-pixels to postscript pixels (multipling each coordinate by (96/163)) and then rounding it to nearest integer

2. translate each (x,y) to (x - minx + dot_radius + edge_padding, y - miny + dot_radius + edge_padding) where edge_padding is set to .25*dot_radius.

3. drawing the points and lines using Tkinter

All looks good in appearance on pdf (sample attached). On monday we should test hand-drawn cards of a couple of these using conductive pen and then testing it out on the reader to see if it returns a close enough set of lengths.
