Convert Bitmap to Byte array WITHOUT Bitmap.CompressFormat

Question

Is there a way to convert bitmap to byte array without the Bitmap.CompressFormat class in Android? if not, how comes? if its is possible, please let me know how, thanx

Answer 1

Something like this?

//b is the Bitmap

//calculate how many bytes our image consists of.
int bytes = b.getByteCount();
//or we can calculate bytes this way. Use a different value than 4 if you don't use 32bit images.
//int bytes = b.getWidth()*b.getHeight()*4; 

ByteBuffer buffer = ByteBuffer.allocate(bytes); //Create a new buffer
b.copyPixelsToBuffer(buffer); //Move the byte data to the buffer

byte[] array = buffer.array(); //Get the underlying array containing the data.
