convert image format iPad

Hi Guys,

i am using the Camera control to capture a picture that i want to upload to sharepoint via power automate flow.

I am stuck at converting the format to binary so the flow works...

I have:

ClearCollect(colPhoto, Camera1.Photo)

when I print First(colPhoto).Value

on the ipad air 5 i get:

/SessionStorage/841ED2CA-E651-402F-972F-4F81B8DC0F4B.jpeg

for the browser (edge) capture i get:

data&colon;image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAoAAAAHgCAYAAAA10dzkAAAAAXNSR0IArs4c6QAAIABJREFUeF6kvWmzZcl1HZb3vfvmGl5NXVU9sEdMBAnQGmxJNElZZtikbOmrZcp2hKwIO/wnFPoi2vpkfXDYDjuCsmQrLFshWUFRks0IwiQBAgQBEkADaICNHtCoHqqrqmt+83Ada629MvfJe241ZL2I7vfqDufkydy599prDzn563/tP5+dnp6W6fK0r [...] (like a million characters long)

so there is definitely a mismatch in formats here.. i tried the dataUriToBinary function and base64ToBinary but none of them work, i always get

Unable to process template language expressions in action 'Compose' inputs at line '0' and column '0': 'The template language function 'dataUriToBinary' expects its parameter to be formatted as a valid data URI. The provided value '/SessionStorage/5C573612-E4EE-4C0E-830C-9703DDB10BD3.jpeg' was not formatted correctly.

It works on browser, just not on the ipad

Any help would be much apprechiated, thank you!

@SteveDaPirate - Maybe just use the expression below -

base64ToBinary(replace('<yourimagevaraible>', 'data&colon;image/jpeg;base64,', ''))

@CFernandes
Hi, thanks for the answer, just so that i understand it correctly - for my case it would be this?
base64ToBinary(replace('Createfile_FileContent', 'data&colon;image/jpeg;base64,', ''))

i get this error now
Unable to process template language expressions in action 'Compose' inputs at line '0' and column '0': 'The template language function 'base64ToBinary' was invoked with a parameter that is not valid. The value cannot be decoded from base64 representation.'.

This is what I think should work... Hardcoded the binary string

base64ToBinary(replace('data&colon;image/jpeg;base64,iVBORw0KGgoAAAANSUhEUgAAAAUAAAAFCAYAAA CNbyblAAAAHElEQVQI12P4//8/w38GIAXDIBKE0DHxgljNBAAO9TXL0Y4OHwA AAABJRU5ErkJggg==', 'data&colon;image/jpeg;base64,', ''))

@CFernandes i think there is a little misunderstanding here - in browser i get the base64 data directly and there the converting with base64ToBinary works, that is no problem.
just on the ipad, the photo is saved as "/SessionStorage/841ED2CA-E651-402F-972F-4F81B8DC0F4B.jpeg" - insert that as your variable and it also doesnt work -
i need to convert that variable to base64/ binary so that i can use it. do you know about any function in that regard?

@SteveDaPirate - Lets step a little back, so you get "/SessionStorage/841ED2CA-E651-402F-972F-4F81B8DC0F4B.jpeg" in the variable? rather than base64 or dataURI?

@SteveDaPirate - So in PowerApps you are using JSON function and then passing variable in PowerAutomate?

Set(myVar; JSON(Image; IncludeBinaryData))

@CFernandes currently i am saving the camera data in power apps as
ClearCollect(colPhoto, Camera1.Photo)
and then i call the flow with this as Photo variable:
First(colPhoto).Value
in the flow i used (see screenshot attached)
base64ToBinary(triggerBody()['Createfile_FileContent'])

i now tried collecting with the json function that you mentioned,
ClearCollect(colPhoto, JSON(Camera1.Photo; JSONFormat.IncludeBinaryData))
that gives me "B" as variable value ^^
