How to get the current instance?

[mexac]

When I call the plugin method "$('.sigPad').signaturePad(options)" on the HTML element it also returns and API for the instance, so we can assign it to some global variable
var sigPad = $('.sigPad').signaturePad(options);

Is it possible to change the method signaturePad(options) so it will return the current instance (or create a new instance if it was not done previously)?
For example:
var img = $('.sigPad').signaturePad().getSignatureImage();

at present it creates a new instance and returns empty image. I have to use a global variable to solve it

Also regarding option.lineTop. IMHO it's better to use it as %.
function drawSigLine() {
...
canvasContext.moveTo(settings.lineMargin, element.height * settings.lineTop * 0.01)
...
}

Thanks.

Yeah, it seems like this is a common issue. I'll change the initialization method to act this way also.

Hi,

I am facing an issue, not able get the output of the capture image, since the getSignatureImage() displays only 0. Please advise what to do
