Signature Gallery: Converting back to image

(0) Share

Posted on by Axeum

Hello all,

I've been working on building a signature capture feature for my app for some time now and I am hoping you can be of assistance.

I started with the Pen Input and then using the variable formula I then trigger my flow.

1 (2).PNG

Within my Flow, I used the below expression for the File Content.

base64ToBinary(triggerBody()['CreateFile_FileContent'])

All of this so far works fine and it uploads to my SharePoint list.

However, it lists it within my SharePoint list as a Hyperlink. I need to make it visible as an image within SharePoint so that it can then be displayed in the app as a gallery.

I'm not sure if this could be done with an additional section to my flow where it converts the image somehow but this is the current limit of my technical knowledge.

Any help in making this signature visible would be greatly appreciated, thank you.

@Axeum ,

If you look further down in the blog, you will see the syntax for viewing. What code have you tried?
