# init(output:rasterSampleCount:enableTonemap:enableColorMatch:alphaPremultiply:maxCameraCount:)

Creates a configuration with the given output format, MSAA sample count, and flags.

## Declaration

```swift
init(output: LowLevelRenderer.Configuration.Output, rasterSampleCount: Int, enableTonemap: Bool = true, enableColorMatch: Bool = false, alphaPremultiply: Bool = true, maxCameraCount: Int = 1)
```

## Parameters

- `output`: The pixel format configuration for the renderer’s output attachments.
- `rasterSampleCount`: The number of samples per pixel for MSAA.
- `enableTonemap`: When true, HDR output values are tone-mapped before writing to the output texture. Defaults to true.
- `enableColorMatch`: When true, a gamut conversion matrix from renderer.colorMatch is applied during resolve. Defaults to false.
- `alphaPremultiply`: When true, the renderer divides content by alpha before applying tonemap and color match, then multiplies by alpha before final texture output. Defaults to true.
- `maxCameraCount`: The maximum number of simultaneous cameras supported. Defaults to 1.
