Base64 String to Image

Posted on by RonanIreland

Hey All,

Hoping someone out there can help!

I have a Power Apps where I'm collecting multiple signatures (It's an online sign-in sheet) and passing them via collection to power automate. I'm then adding them to create html table and emailing the output of the html table.

My Flow is working and emailing the base64 in String format but I can't for the life of me get it to output an image instead.

Basically I'm looking for a way to change output in the html table from string format to image.

Many thanks,

Ronan

Hey Sanmesh,

Thanks a mill for getting back to me.

I checked out your previous solution and tried to use it in mine but I'm still having issues.

I think it's because I already have binary without data&colon;image/jpeg;base64,

This is what I use in power apps to get it.

Updating Collection with image value:
UpdateIf(colTBTBulkcombined,Email=galTloTrainingType_3.Selected.Email,{Signature:PenInput2.Image,JSONpenIput:Mid(JSON(PenInput2.Image,JSONFormat.IncludeBinaryData),24,Len(JSON(PenInput2.Image,JSONFormat.IncludeBinaryData))-24)});

Run:
signaturetohtmltable.Run(JSON(colTBTBulkcombined,JSONFormat.IncludeBinaryData));

Because I'm using a collection and Parse JSON I can't get the outputs('JSONpenIput')?['$content'] to work.

Can you please help with the code I should be entering here for this to work.
Many thanks,

Ronan
