Is there any way to ignore transparent background in png?

[arsenanai]

Hi, I'm trying to convert signature to vector image. I have png image with transparent background, but when I transform image to SVG, it fills out whole backgound with colored path. Is there any way to avoid that.
Used options:

            //detailed
            pathomit:0, 
            roundcoords:2, 
            ltres:0.5, 
            qtres:0.5,
            //curvy
            linefilter: true,
            rightangleenhance:false,
            //grayscale
            colorsampling:0, 
            colorquantcycles:1, 
            numberofcolors:2,

Another question is: Can you advice me best option to make curved, smooth and noisyless options, thanks
