It will then be able to 'decode' the fil and reconstruct it. I've followed a few guides online, but I can't seem to get anything to work. My understanding is that I need to break the Bitmap into it's BitmapData components, convert that to a 'byteArray' which is saved, (or ...

Android Bitmap 和 ByteArray的互相转换 移动平台图像处理,需要将图像传给native处理,如何传递?将bitmap转换成一个 byte[] 方便传递也方便cpp代码直接处理图像内容。 Bitmap -> byte[] 创建一个ByteBuffer用于接收数据。首先需要爲buffer开辟内存空间,内存空间的大小就是图片的大小。将bitmap的数据写入...
