# XamlToBitmap.Render

Renders XAML with binded data context into the in-memory bitmap stream.

## How to use

```csharp

public async Task Main()

{

    await RenderToBitmap(

        "./assets/weather-template.xaml",

        // Use streams not strings! This is just a short example.

        JsonSerializer.Deserialize(

            File.ReadAllText( "./data/forecast.json" ) ),

        new XamlRender(),

        $"./outbox/image{DateTime.Now.Ticks}.png"

    );

}

public static async Task RenderToBitmap(

    string pathToXamlFile,

    object dataContext,

    IContentRender renderer,

    string saveToPath )

{

    using Stream stream = File.OpenRead( pathToXamlFile );

    using MemoryStream imageStream =

        await renderer.RenderAsync(

            stream, dataContext,

            XamlRender.ThermalPrinter_CommonDpi,

            XamlRender.ThermalPrinter_CommonDpi );

    File.WriteAllBytes( saveToPath, imageStream.GetBuffer() );

}

public const double ThermalPrinter_HiResDpi = 304;

```
