A RAW "image" is not really an image. RAW“图像”并不是真正的图像。 It represents the raw (hence the name) sensor data from the camera.它代表来自相机的原始（因此得名）传感器数据。 To get a bitmap you would need to "develop" the photo.要获得 bitmap，您需要“显影”照片。
However a good, general-purpose algorithm for developing a RAW photo is very hard to develop.但是，很难开发出用于开发 RAW 照片的良好通用算法。 If I knew a bit more about your situation I could suggest a possible solution but I think your best bet is either using the developed image directly or find some way to convert it using a preexisting algorithm.如果我对您的情况有更多了解，我可以提出一个可能的解决方案，但我认为您最好的选择是直接使用开发的图像，或者找到某种方法使用预先存在的算法对其进行转换。
I strongly recommend the former because the phone's built-in algorithm will most likely be better than whatever library you might find.我强烈推荐前者，因为手机的内置算法很可能比你可能找到的任何库都要好。
