I would like to display pulled from a database on an image on a Vision window. I understand I can do this with a paintable canvas component.
I have read “all” the posts on this forum and tried most options.
I suspect that my image blob is not correct format.
I am generating the image via an OpenCV python script. Database is MariaDB, column type is blob.
When I pull it out in Ignition the datatype is either ndArray (numPy) or unicode.
I have deduced (perhaps incorrectly) that neither of these is correct.
Has some one done this successfully?
Precisely what format do I need to generate in my python script?
