Question

我正在将一些图像导入我的应用程序，并在编辑后稍后将其导出。 UIImage的大小似乎大于原始数据。

getS1I1_indirect ssiClosure = show(getS1 ssiClosure) ++ ", "  ++ show(getI1 ssiClosure)

    • Couldn't match type ‘[Char]’ with ‘Int’
      Expected type: ([Char] -> [Char] -> Int -> Int) -> Int
        Actual type: ([Char] -> [Char] -> Int -> [Char]) -> [Char]
    • In the first argument of ‘getI1’, namely ‘ssiClosure’
      In the first argument of ‘show’, namely ‘(getI1 ssiClosure)’
      In the second argument of ‘(++)’, namely ‘show (getI1 ssiClosure)’

let imageData = myData
print("Imge size at import: \(imageData.count)")
print("Imge size at import JPGRepresentation: \(UIImageJPEGRepresentation(UIImage(data: imageData)!, 1)!.count)")
print("Imge size at import PNGRepresentation: \(UIImagePNGRepresentation(UIImage(data: imageData)!)!.count)")

根据其他答案，这似乎是正常的： imageWithData image size become bigger?

现在的问题是：是否可以在不损失质量的情况下获取大小为Imge size at import: 88174 Imge size at import JPGRepresentation: 185973 Imge size at import PNGRepresentation: 425187的数据？如果使用88174，我会失去质量。

重新格式化：是否可以解压缩和压缩质量和尺寸相同的JPG图像？

图像数据不失质量
