Hey Everyone,
I'm working on integrating my verifone Topaz POS register with blue iris. The ideas is that once a cashier rings up an item, I can overlay the register output over the camera feed. So far I have been able to capture the text over an RS-232 com port and wrote a python script that listens for incoming data and writes the data to a txt file. This file is linked with blueiris via macros and displays the register output for the given transaction.
My problem is the overlay resizing that blueiris uses causes the text to keep changing size as more items are added to a register queue. I have attached a picture below with 1 item and with multiple items. Notice how the scaling changes. I have tries resizing the overlay box with static text, but it keeps changing size with every new line.
Can anyone help me find a work around or a way to expand the functionality of BI to keep the overlay size static?
As a side not, the overlay data is not recorded to the DVR and can only be view via live stream. Any way to make it record the text?
