The link on the comment is currently broken. Due to the fact that the folder "samples" might change path in the future again, whoever needs can start exploring from the https://github.com/mono/SkiaSharp page.
More information about using SkiaSharp can be found on the API documentation online and in this article about drawing with skia sharp
For who needs a practical quick start on how to use it here some examples:
Getting an SKCanvas
using (var surface = SKSurface.Create (width: 640, height: 480, SKColorType.N_32, SKAlphaType.Premul)) {
SKCanvas myCanvas = surface.Canvas;
// Your drawing code goes here.
}
Drawing Text
// clear the canvas / fill with white
canvas.DrawColor (SKColors.White);
// set up drawing tools
using (var paint = new SKPaint ()) {
paint.TextSize = 64.0f;
paint.IsAntialias = true;
paint.Color = new SKColor (0x42, 0x81, 0xA4);
paint.IsStroke = false;
// draw the text
canvas.DrawText ("Skia", 0.0f, 64.0f, paint);
}
Drawing Bitmaps
Stream fileStream = File.OpenRead ("MyImage.png");
// clear the canvas / fill with white
canvas.DrawColor (SKColors.White);
// decode the bitmap from the stream
using (var stream = new SKManagedStream(fileStream))
using (var bitmap = SKBitmap.Decode(stream))
using (var paint = new SKPaint()) {
canvas.DrawBitmap(bitmap, SKRect.Create(Width, Height), paint);
}
Drawing with Image Filters
Stream fileStream = File.OpenRead ("MyImage.png"); // open a stream to an image file
// clear the canvas / fill with white
canvas.DrawColor (SKColors.White);
// decode the bitmap from the stream
using (var stream = new SKManagedStream(fileStream))
using (var bitmap = SKBitmap.Decode(stream))
using (var paint = new SKPaint()) {
// create the image filter
using (var filter = SKImageFilter.CreateBlur(5, 5)) {
paint.ImageFilter = filter;
// draw the bitmap through the filter
canvas.DrawBitmap(bitmap, SKRect.Create(width, height), paint);
}
}
