iOS以“翻转行序”格式保存bmp。是否可以在Swift中删除此选项？

import UIKit

func saveBMPWithoutFlipping(image: UIImage, filePath: String) {
    guard let cgImage = image.cgImage else {
        return
    }
    
    let width = cgImage.width
    let height = cgImage.height
    let bitsPerComponent = 8
    let bytesPerPixel = 4
    let bytesPerRow = width * bytesPerPixel
    
    let colorSpace = CGColorSpaceCreateDeviceRGB()
    let bitmapInfo = CGBitmapInfo.byteOrder32Little.rawValue | CGImageAlphaInfo.premultipliedLast.rawValue
    
    guard let context = CGContext(data: nil, width: width, height: height, bitsPerComponent: bitsPerComponent, bytesPerRow: bytesPerRow, space: colorSpace, bitmapInfo: bitmapInfo) else {
        return
    }
    
    context.draw(cgImage, in: CGRect(x: 0, y: 0, width: width, height: height))
    
    guard let data = context.data else {
        return
    }
    
    let buffer = UnsafeBufferPointer(start: data.assumingMemoryBound(to: UInt8.self), count: height * bytesPerRow)
    let imageData = Data(buffer: buffer)
    
    do {
        try imageData.write(to: URL(fileURLWithPath: filePath))
        print("BMP file saved successfully.")
    } catch {
        print("Failed to save BMP file: \(error)")
    }
}

// 使用示例
let image = UIImage(named: "example_image")
let filePath = "/path/to/save/image.bmp"
saveBMPWithoutFlipping(image: image, filePath: filePath)
