have an error when try directory.readRasters()

[IhorKram]

this is my code:

    let tiffImage: TIFFImage = TIFFReader.readTiff(from: data)
    let directories: [TIFFFileDirectory] = tiffImage.fileDirectories()
    
    for directory in directories {
        let rasters: TIFFRasters = directory.readRasters() <-------ERROR
    }

this is an error:

libc++abi: terminating with uncaught exception of type NSException *** Terminating app due to uncaught exception 'Unsupported Compression', reason: 'JPEG compression not supported: 7' terminating with uncaught exception of type NSException

JPEG compression is currently not supported.
