Camera Image data changed Format

[Jissenka]

Hi,

I'm Hoping someone can shed some light on my problem, I have created an app that uses the camera to take and photo and saves the image data to a sharepoint list, This has been working fine and the images are viewable in a gallery.

However of late I noticed the image data stored on sharepoint is different (see below), and now the new format cannot be viewed.

Old format "data:image/png;base64,i(StingOfCharacters)"

New format "/SessionStorage/PApps(StringOfNumbers).png"

Can someone explain what has caused the change and how to get it back or at least get the images to be viewable again.

I have added a screenshot of both datastrings from sharepoint.

Thanks in advance,

Hi @Jissenka ,

What are you using to store the code (I assume JSON conversion). Can you please post the code.

Thanks for the reply,

I have only given the code related to the image, and Changed the real list name for reasons.

if the device is online it is a patch command from the photo collection

 Patch(MySharepointList,Defaults(MySharepointList),

{

Image_Data: First(colPhoto_1).Url

}

If offline  it collects the data to an offline collection

Collect(
colTaskOffline,{

colImage_Data: First(colPhoto_1).Url

}

And when back online it patches the data from the collection to the sharepoint list

Patch(MySharepointList,Defaults(MySharepointList),

{

Image_Data: colImage_Data

}

Again this code hasn't changed, but the output in sharepoint has. I'm not sure what could have done it

The crux is all I want is an image that is viewable in the app, and best case in a format that can be used external to powerapps (that's the final goal).

HI @Jissenka ,

Your Patch needs to follow this

With(
   {
      wJSON: 
      Substitute(
         JSON(
            First(colPhoto).Url,
            JSONFormat.IncludeBinaryData
         ),
         """",
         ""
      )
   },
   Patch(
      YourListName,
      {YourRecordIdentifier},
      {YourFieldName: wJSON}
   )
)

I have set this out in this section of my blog on images

Thanks WarrenBelz,

that worked, any idea why it would have worked originally then changed?

Thanks @Jissenka ,

I am surprised it worked in the first place - I have always used the JSON "quote stripping" formula provided.
