# canBeCompressed(using:)

Tests whether the bitmap image representation can be compressed by the specified compression scheme.

## Declaration

```swift
func canBeCompressed(using compression: NSBitmapImageRep.TIFFCompression) -> Bool
```

## Parameters

- `compression`: A TIFF compression type. For more information, see the constants in doc://com.apple.appkit/documentation/AppKit/NSBitmapImageRep/TIFFCompression.

## Return Value

Return Value true if the receiver’s data matches compression with this type, false if the data doesn’t match compression or if compression is unsupported.

## Discussion

Discussion This method returns true if the receiver’s data matches compression; for example, if compression is NSBitmapImageRep.TIFFCompression.ccittfax3, then the data must be 1 bit per sample and 1 sample per pixel.
