Ink Sketch on a Public Form

I would like to save the user signature from the Ink Sketch on a public form to a SharePoint list. I'm trying to follow the article below but it keeps giving a big number instead of the image. What am I doing wrong?

Hello @adasilva,

You need to design a form for SharePoint list using the Plumsail Forms for SharePoint. Please find the instructions here:

Thank you. Is there a way to save the ink sketch with Public Form or with Public Form is not possible?

@adasilva,

You can save the signature as an image in Power Automate Flow. Please see the MS instructions.

Hi Margarita,

I tried putting the value from the ink sketch on the formula
base64ToBinary(your_base64_string) but got an error message.

BinaryError
BinaryError756×584 19.8 KB

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.'.

I basically created a variable called vareu, type string and set the value for the plumsail ink sketch.

Then used a compose with the formula base64ToBinary(variables('vareu'))

but it is not working, please advise what I'm doing wrong.

Never mind we figured it out, you have to removed the data:image/png;base64 first.
