How to draw Signature in SAP Build apps

[karthiknagireddy]

Dear All, 
Good day,

I have developed a application in Build apps. My requirement to capture the signature of the end user in the signature canvas.

I have verified in the market place and found the signature component available in the market place. But unable to implement in the UI canvas.

Any assistance/guidance on this requirement is highly appreciated.

Thank you in Advance.

The flow function works on mobile only and essentially will create an image for you that is stored in cache of the mobile device. You can easily display the signature by adding an image component and setting its "Source" to the path field of the output of the "Draw Signature" flow function.

Here I have a button and an image components, with a logic flow for button tap.

For the set page variable for the variable connected to the image, I set the page variable to the path of the signature.

Here's the app.

Open the draw component and sign.

Now it appears in the image.

You can treat it like an image file and upload it somewhere or move it on the phone or whatever.

Hope that helps.

Hi Dan,

is there a chance to get it running on a pc?

I hear your pain but I'm not in charge of the product so it's not up to me.

Dear all, the screenshot is about the signature box on an Iphone, I suppose. When shown on Android, the signature box has no style at all, being white box, no border, on a white plain background, meaning that it's impossible for the users to understand where they have to sign. Please consider to support this request to the product team:
- assign to the box at least a thin borde, a full page width and height and a light gray background
- giving the style properties to the draw signature component, to change the dimensions, the colour, the border and the background

Please let me know if taking this request to the attention of the developers is something that can be done this way.

Thank you, Dan, for your article.

There used to be a mailbox to which you could send your issues, perhaps feature request: buildapps@sap.com

At least in the past this was monitored closely, and as recently as a month ago this email was promoted by SAP.
