Is there a way to save the signature data from canvas as JPG?
I would like to include the signature in my pdf Report.


Could you help me, please?

Thanks a lot.

Hi Erel,

thank you. Unfortunelly the Background Color of the png is black. I can't see the signature.

 

[Erel]

Does it happen with the SignatureCapture example?

 

[ST500]

Yes Sir.
I tried it again. You must set white as backgroundcolor for the panel. But that's my problem.
I need my panel transparent.

Does it happen when you run the SignatureCapture project as-is?

I use the SignPad library, it allows you to save the signature with a transparent background.
