### CameraStreamer C# Event Handlers and Methods
Source: https://github.com/baltermia/blazor-camera-streamer/blob/main/README.md
Provides C# code examples for handling the OnRendered and OnFrame events of the CameraStreamer component. It also shows how to get camera access, reload the stream, and process received image data.
```csharp
CameraStreamer CameraStreamerReference;
string cameraId = null;
private async void OnRenderedHandler()
{
// Check camera-access or ask user, if it's not allowed currently
if (await CameraStreamerReference.GetCameraAccessAsync())
{
// Reloading re-initializes the stream and starts the
// stream automatically if the Autostart parameter is set
await CameraStreamerReference.ReloadAsync();
// If Autostart is not set, you have to manually start the stream again
/* await CameraStreamerReference.StartAsync(); */
}
}
private void OnFrameHandler(string data)
{
// Remove the suffix added by javascript
data = data[(data.IndexOf(',') + 1)..];
// Convert the base64 string to a System.Drawing.Bitmap
Bitmap bmp = new(new MemoryStream(Convert.FromBase64String(data)));
// Do something with the bitmap
}
```

### Getting Current Frame Individually
Source: https://github.com/baltermia/blazor-camera-streamer/blob/main/README.md
Demonstrates how to retrieve the current camera frame as a base64 string using the GetCurrentFrameAsync method, as an alternative to the OnFrame callback.
```csharp
string imageData = await CameraStreamerReference.GetCurrentFrameAsync();
```

### Configure SignalR for ServerSide Blazor
Source: https://github.com/baltermia/blazor-camera-streamer/blob/main/NUGET-README.md
C# code to configure the maximum receive message size for SignalR in a ServerSide Blazor application. This is crucial for handling larger image data from the camera stream, bypassing the default 32KB limit.
```csharp
services.AddServerSideBlazor()
.AddHubOptions(o => o.MaximumReceiveMessageSize = 100_000_000); // add this
```

### Configure SignalR for ServerSide Blazor
Source: https://github.com/baltermia/blazor-camera-streamer/blob/main/README.md
For ServerSide Blazor, SignalR has a default message size limit that can restrict camera stream data. This C# code snippet shows how to increase that limit in your `ConfigureServices` method to handle larger image data.
```csharp
services.AddServerSideBlazor()
.AddHubOptions(o => o.MaximumReceiveMessageSize = 100_000_000); // add this
```
