"Prewarp" with cloud web service



i cannot seem to get the prewarp feature to work with the cloud API. i would like to supply regexp characters for plate pattern matching like so:

What is the correct syntax?



The prewarp feature has been deprecated in the latest release of the software. Recent improvements in the last year for deskew has made it much more accurate at angles. Now the prewarp generally causes more harm than good in the commercial engine.
