POS text overlay

Post by qkumbr » Wed Jul 25, 2012 2:08 am

Greetings,

My company installs POS systems and camera systems. We've been using DVRs with D1/CIF for years but are looking to break ties with our supplier due to frequent hardware failures. Additionally we're looking for NVR software that supports megapixel cameras for better quality.

Our POS system outputs activity from the point-of-sale through a Windows service. The service outputs activity to a serial port, or over UDP ports through the network. With this service, an intercepting piece of hardware between the point-of-sale and the printer is not necessary

Is it feasible for ZoneMinder to support TCP/IP- and/or RS232-based text overlay?

Here's an example of the point-of-sale text overlay I'd like ZoneMinder to be able to do:

there is a feature today that allows you to add a "text overlay" using zmtrigger. The concept is you use zmtrigger to trigger an event when a POS happens and pass an option to add a custom text overlay. The problem however is that the overlay is only restricted to the timestamp bar at the top - but you can start there.

our code is supposed to handle \n's so multi-line should work.

I've been meaning to overhaul the label code anyways. I think it is inefficient and hey wouldn't anti-aliasing and variable size fonts be nice?!
