# SkiaSharp

Welcome to SkiaSharp, the most awesome, cross-platform 2D-graphics engine. It is powered by the same engine that powers Android and Chrome.

The first thing we need to do is intsall the package:

#!csharp

#i https://aka.ms/skiasharp-eap/index.json
#r nuget:SkiaSharp,2.80.*-*

#!markdown

After installing the `SkiaSharp` NuGet package, we can now add the typical `using` statements:

#!csharp

using SkiaSharp;

#!markdown

Now, we can start coding. Here we create a simple 256x256 canvas:

#!csharp

// create the bitmap that will hold the pixels
var bitmap = new SKBitmap(256, 256);

// create the canvas so that we can draw on that bitmap
var canvas = new SKCanvas(bitmap);

// clear the canvas, so that it is fresh
canvas.Clear(SKColors.Transparent);

#!markdown

Before we can draw anything, we need to create the object that will be used to describe how the thing we are drawing will look. To do this, we need a `SKPaint` object:

#!csharp

var paint = new SKPaint {
    IsAntialias = true,                               // smooth text
    TextSize = 50,                                    // 50px high text
    TextAlign = SKTextAlign.Center,                   // center the text
    Color = 0xFF3498DB,                               // Xamarin light blue text
    Style = SKPaintStyle.Fill,                        // solid text
    Typeface = SKTypeface.FromFamilyName("Trebuchet") // use the Trebuchet typeface
};

#!markdown

Now that our canvas is all ready, we can start drawing. Here we are writing the word “SkiaSharp” in the middle:

#!csharp

// clear the canvas, just in case we are running this a second time
canvas.Clear(SKColors.Transparent);

// draw the text using the paint
canvas.DrawText("SkiaSharp", 128, 128 + (paint.TextSize / 2), paint);

// appear in VS Code
bitmap

#!markdown

Thats it! So simple! And, best of all, this code can be used ANYWHERE!
