Blazorex

Description

Blazorex is an HTML Canvas wrapper library for Blazor.

Doom fire effect with Blazorex

It has some interesting functionalities like:

  • multiple canvases
  • background rendering
  • image rendering
  • procedural image generation (yes, the fire on the background is fully procedural! Thanks filipedeschamps for the awesome repository showing how to render the Doom fire! )

Installation

Blazorex can be installed as Nuget package: https://www.nuget.org/packages/Blazorex/

Usage

Simple scenario

Just add the Canvas Component to your Razor page and register to the OnCanvasReady to receive the CanvasBase instance.

Then use OnFrameReady to define your update/render logic:

<Canvas Width="800" Height="600" 
        OnFrameReady="(t) => OnFrameReady(t)"
        OnCanvasReady="(ctx) => OnCanvasReady(ctx)" />

@code{
    CanvasBase _canvas;

    private void OnCanvasReady(CanvasBase canvas)
    {
        _canvas = canvas;
    }

    private void OnFrameReady(float timeStamp)
    {
        // your render logic goes here
    }
}

You might also need to update your index.html to include the library's CSS:

<head>
    
    <link href="_content/Blazorex/blazorex.css" rel="stylesheet" />
</head>

Multiple Canvases

In case you want to have multiple canvases on the same page, you can use the CanvasManager component instead:

<CanvasManager @ref="_canvasManager" />

@code{
        CanvasManager _canvasManager;
        
        protected override async Task OnAfterRenderAsync(bool firstRender)
        {
            if (!firstRender)
                return;
        
            _canvasManager.CreateCanvas("myCanvas", new CanvasCreationOptions()
            {
                Width = 800,
                Height = 600,
                Hidden = false,
                OnCanvasReady = this.OnMyCanvasReady,
                OnFrameReady = this.OnMyCanvasFrameReady,
            });
        }
}

You simply have to get a reference to the CanvasManager and then call the CreateCanvas passing an instance of CanvasCreationOptions with the desired parameters.

For a complete list of options for Canvas initialization, see here.

For the complete documentation, check the official website

The ./samples folder contains some examples of how to setup the canvas and draw some cool stuff 😃
