英文:
Save image without compressing
问题
在我的应用程序中，我使用相机拍摄照片，并将图像存储到内部存储中，但是当我检索存储的图像时，图像的质量变得非常差。是否有任何方法可以在不压缩的情况下存储实际图像？
以下是保存图像的代码部分：
private fun saveImage(bitmap: Bitmap): Uri {
val wrapper = ContextWrapper(applicationContext)
var file = wrapper.getDir(IMAGE_DIRECTORY, Context.MODE_PRIVATE)
file = File(file, "${UUID.randomUUID()}.png")
try {
val stream: OutputStream = FileOutputStream(file)
bitmap.compress(Bitmap.CompressFormat.PNG, 100, stream)
stream.flush()
stream.close()
} catch (e: IOException) {
e.printStackTrace()
}
return Uri.parse(file.absolutePath)
}
