File attachment as base64

[robdove]

I'm attempting to upload an image as base64 encoding.

I've tried to follow the Craft documentation for assets fields - https://craftcms.com/docs/3.x/assets-fields.html#creating-new-assets

<input type="hidden" name="attachment[data][]" value="data:image/jpeg;base64,my-base64-data......">
<input type="hidden" name="attachment[filename][]" value="filename.jpg">

Is it possible with this plugin?

I will make this a high-priority request. I am hoping to get it out quickly.

@robdove I was looking into this request, I apologize I thought it was a bug, but I am confused about how this is being used. I can modify the File field type to allow base64 data to be uploaded, but I am failing to understand how a file is being uploaded as data to begin with. Some more context may help me understand the problem and a concrete solution.

thanks for looking @xpertbot

I'm creating a screenshot of an element on the page using html2canvas. I then need to upload this image with the form so it's stored on the server and also emailed as part of the submission. I can only create a base64 encoded image on the front end to be uploaded. The Craft docs have an example how to upload an asset in this format and was hoping this could also be used with Wheelform.
