Posted on by superfliege 91

Hello together,

 

i have a canvas app on a pc. I want to scan a business card threw the webcam.

The business card scanner widget opens the windows "file open" dialog. Here i can select a picture.

 

But i want to use the webcam from my pc as datasource.

 

How i can use the business card scanner with a webcam? 

 

best greetings

    Hi @superfliege ,

    I've made a similar test and I found that:

    1)in website, the business card scanner could only scan local images.

    2)in mobile phone app, the  the business card scanner could be used as a camera and scan captured images.

    I'm afraid it's not supported to use  business card scanner on a pc with webcam.

    For now, you could only choose local images to scan in business card scanner.

    I suggest you express your views about adding this function on PowerApps Ideas Forum. Your precious feedback will be very helpful for our work.

    Ai model is still a function in experimental process. I believe it will improve in the future.

    Really very sad, since the functionalities are all there and you simply cannot "link" them properly.
    But I can understand that because these functions are all very new.

    I posted an idea:

    I have also found a workarround:

     

    1. Using a camera component and save the image to a variable

    2. Convert the variable with PNG Image to a JPG Image with a JavaScript component.

    4. Send the Image to a "Parent Flow". This "Parent Flow" is only a wrapper for the childflow, because you can not link the "Predict - Common Data Service (Current Environment)" directly to the Powe App. When you want link the flow from step 5 this message accours: "Send HTTP Request Error"

     

    5. In the child flow use this flow:
