I watched the following PowerApps ComputerVision OCRText video:

https://www.youtube.com/watch?v=qXSRKfYqYMM&t=844s

Has Microsoft resolved this so that the ComputerVision OCRText connector will work directly within PowerApps without having to use Flow as discussed in the video above ?

If so, can someone please describe the exact syntact to execute the OCRText Command on an image?

We would prefer to not use Flow, if possible.

Thank you.

Thank you, Michael. Are you saying this works without Flow ?
That was our goal, to not have to use Flow with this product.

Followed the youtube example from Paul, but I am getting an error message from the following expression on the flow Set(varOCR,OCRTest.Run(First(colPhoto).Url).ocrtext) "Invalid number of argument received 1 expected 2" any ideas where I have gone wrong??

Thanks
Michael.
