Resize an image and draw some overlay text with SkiaSharp

ResizeWithSkia.cs

            var toBitmap = new SKBitmap((int)Math.Round(bitmap.Width * resizeFactor), (int)Math.Round(bitmap.Height * resizeFactor), bitmap.ColorType, bitmap.AlphaType);

            var canvas = new SKCanvas(toBitmap);

Do you really need to Dispose of everything created? I don't condemn it, just curious. Most examples I saw, don't use Dispose method.

Disposing frees resources earlier. Alternatively you can use using which will call it automatically for you.

There is an error on the line 36. Changing the SKImageEncodeFormat to SKEncodedImageFormat solve that.

Thanks! helped me a lot as I was struggling to get this to work

Please update documenation to reflect

Thanks! i have an other question, how to solve text auto swrap.
