# bestDepth(colorSpaceName:bitsPerSample:bitsPerPixel:isPlanar:)

Determines the best window depth that most closely matches the given properties.

## Declaration

```swift
static func bestDepth(colorSpaceName: NSColorSpaceName, bitsPerSample: Int, bitsPerPixel: Int, isPlanar: Bool) -> (NSWindow.Depth, isExactMatch: Bool)
```

## Parameters

- `colorSpaceName`: The name of a color space to match.
- `bitsPerSample`: The bits per sample to match.
- `bitsPerPixel`: The bits per pixel to match.
- `isPlanar`: A Boolean that indicates whether the window depth is planar.

## Return Value

Return Value The window depth that most closely matches the properties this function requests.
