# retagging(with:)

Changes the color space tag of the bitmap image representation.

## Declaration

```swift
func retagging(with newSpace: NSColorSpace) -> NSBitmapImageRep?
```

## Parameters

- `newSpace`: The desired color space.

## Return Value

Return Value An NSBitmapImageRep, or nil, if the conversion fails. If the original NSBitmapImageRep already uses that color space, it is returned as is.

## Discussion

Discussion This method will definitely fail if you pass a color space that has a different color space model than the receiver. That is, if your original image is sRGB, you can only retag with some other RGB colorspace.
