我得到的图像从数据库中的BLOB格式。我想将其转换成用位图转换为BLOB是把below.but请告诉我如何扭转它的位图形象。$ C $词。???

  ByteArrayOutputStream蟒蛇=新ByteArrayOutputStream（）;
btmap.com preSS（Bitmap.Com pressFormat.JPEG，100，蟒蛇）; // BM是位图对象
byte []的byteArrayImage =蟒蛇.toByteArray（）;
字符串连接codeDIMAGE = Base64.en codeToString（byteArrayImage，Base64.DEFAULT）;
 

解决方案

这将工作

 字节[]的字节数组= DBcursor.getBlob（参数：columnIndex）;

位图BM = BitmapFactory.de codeByteArray（字节数组，0，byteArray.length）;
 

I am getting image from database in blob format. i want to convert it into Bitmap image.the code i used to convert bitmap to Blob is put below.but please tell me how to reverse it.???

ByteArrayOutputStream boas = new ByteArrayOutputStream();  
btmap.compress(Bitmap.CompressFormat.JPEG, 100, boas ); //bm is the bitmap object   
byte[] byteArrayImage = boas .toByteArray(); 
String encodedImage = Base64.encodeToString(byteArrayImage, Base64.DEFAULT);

This will work

byte[] byteArray = DBcursor.getBlob(columnIndex);  

Bitmap bm = BitmapFactory.decodeByteArray(byteArray, 0 ,byteArray.length);
