native camera & flow

I'm trying to use the Native Camera control announced in this blog post: https://powerapps.microsoft.com/en-us/blog/powerapps-v610/. It works very well.

However I would like to process the image captured with that control, using Microsoft flow. I see a lot of blogs explaining to get the data uri from the image and use that base64 encode string, but that only seems to apply to the built in camera control.

I've seen this thread (https://community.powerapps.com/t5/PowerApps-Forum/Retrieving-Data-URI-from-an-image-added-via-the-quot-Add-picture/m-p/40247) that addresses a similair issue, however I'm not planning to built a custom WebApi. At most an azure funtion, but I'd rather use Microsoft Flow. Any ideas on how this might work? Or any ideas in general on how to use the image from the 'Add Image' control can be used for further processing?

Regards,

Martijn

Re: native camera & flow

Hi Martijn

You and me are doing the exact same thing and I spent some time trying to come up with a way. Glad to see I am not alone!

I have added this to the suggestion box and perhaps vote for it?

Re: native camera & flow

Hi Paul,

I've voted for the suggestion. In the post you describe a function that does the job for you. Could I ask you to post that sample, or give some guidance. I'm not that familiair in working with binary data and Azure Functions.

Regards,

Martijn

Martin,

Paul and I collaborated and build out a Flow-based webservice that can handle PowerApp's binary blob (from media control).

Re: native camera & flow

Hi @Anonymous and @Anonymous ,
Are these solutions still applicable?
I get "Content-Length = 0" from Postman when performing a POST to the Flow Request URL using form-data , File, and selecting either a .png or .jpg file from my computer.
Have tried deleting/recreating the Flows; selecting different images, etc. No go.
Any ideas on what to check?
Thank you

The latest and best trick is using an unused Outlook connector.
