在Android中,将ByteArray转换为Bitmap是一个常见的操作,通常用于处理图像数据。以下是一个详细的步骤说明,包括必要的代码片段: 1. 获取ByteArrayInputStream对象 首先,我们需要将字节数组转换为ByteArrayInputStream对象,这是BitmapFactory解码图像数据的输入源。 java byte[] byteArray = ...; // 你的字节数组 Byt...
imgstream.open(imgfile, FileMode.READ); varimgsource:ByteArray = new ByteArray() imgstream.readBytes(imgsource,0,imgstream.bytesAvailable); imgstream.close(); 2: 将ByteArray转化为BitmapData privatefunctionloaderCompleteHandler(evt:Event):void{ varbitmapData:BitmapData = Bitmap(evt.target.conte...

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buffer,然后调用buff...

Would Method 1 (marshaling bitmap bytes from memory to byte array) work across a TCP stream? When I try to convert the byte array back to a Bitmap on the other computer, .NET throws an exception about corrupted memory. Method 2 is very common, but is much slower than Metho...
