SKPaint is not affecting Picture

[desc3nd]

HI Matthew @mattleibow ,
Apparently SkPaint is not affecting SKPicture when drawing on canvas.
What I'm trying to do is scale picture without changing it's stroke.
I found out that in order to do this I'm supposed to define SkPaint with style Stroke or StrokeAndFill and set StrokeWidth=0.
Here is sample of my code:

using (SKCanvas canvas = new SKCanvas(bitmap))
 {
            var paint = new SKPaint
            { 
                IsAntialias = true,
                Style = SKPaintStyle.Stroke,
                StrokeWidth = 0,
            };
            canvas.Scale(4);
            canvas.DrawPicture(svg.Picture, paint);
}

Could you tell me what am I doing wrong?
Is it possible to scale svg without changing it's edges thickness?

Maybe I misunderstand something but normally SKPicture is a frozen record of already executed drawing operations. So the only thing paint would affect here is how you want to play that song: with which opacity, filters etc, without changing the song notes. You had to change the width of strokes before that SKPicture was created.

Вы можете масштабировать контейнер в котором вы отображаете svg
а потом просто перерисовать svg или трансформировать его
понимаю что это жутко не эффективно, поэтому у меня была мысль в том чтобы изначально нарисовать увеличенную svg картинку в рамках контейнера и увеличивать уже без трасформации, как то так

public void DrawMaps(int ImgWidth, int ImgHeight)
        {
            //SKImageInfo imageInfo = new SKImageInfo(2120, 1170);
            SKImageInfo imageInfo = new SKImageInfo(ImgWidth, ImgHeight);   

            using (SKSurface surface = SKSurface.Create(imageInfo))
            {
                SkiaSharp.SKCanvas canvas = surface.Canvas;


                scaleX = imageInfo.Width / 20955f;
                scaleY = imageInfo.Height / 11530f;
                matrix = SkiaSharp.SKMatrix.CreateScale(scaleX, scaleY);


                paint.IsAntialias = true;
                //ширина обводки
                paint.StrokeWidth = 1f;

                paint.Style = SKPaintStyle.Stroke;

               
                    for (int i = 0; i < listSvgHelper.Count; i++)
                    {
                        transformPath = new SKPath();
                        transformPath.Rewind();
                        transformPath.AddPath(listSvgHelper[i].SKPath);
                        transformPath.Transform(matrix);
                        canvas.DrawPath(transformPath, paint);
                        listSvgHelper[i].TSKPath = transformPath;
                    }
               
                

                // canvas.DrawPicture(svg.Picture,ref matrix);


                //canvas.DrawPath(listPath[0], paint);
                using (SkiaSharp.SKImage image = surface.Snapshot())
                using (SKData data = image.Encode(SKEncodedImageFormat.Png, 100))
                using (MemoryStream mStream = new MemoryStream(data.ToArray()))
                {
                    //using (SKSvg svg = new SKSvg())
                    //{
                    // svg.Load(App.DataSVGPath);
                    Bitmap bm = new Bitmap(mStream, false);
                    //image.
                    pictureBox1.Image = bm;

                    // }
                }
            }
        }
