Is there any way to create an eraser to remove previously created SKPath's? I wish create a new transparent SKPath which will act as an eraser to any previously rendered SKPath's... Please, help me, guys, I'm really going nuts here, thanks in advance.

Hi,
I could achieve it by playing with the blending mode of the skpaint
You have to set transparent color and blendmode as "Src", shomehow like this:
SKPaint _paint = new SKPaint
{
Style = SKPaintStyle.Stroke,
StrokeCap = SKStrokeCap.Round,
StrokeJoin = SKStrokeJoin.Round,
Color = _isDeleting? Color.Transparent : SomeForeColor,
BlendMode = _isDeleting? SKBlendMode.Src : SKBlendMode.SrcOver
(...)
};
when _isDeleting=true, then the drawing action will replace everything in its path for whatever is behind on that canvas' object (color or image)
