I am trying to write a Bitmap file creator to understand the format better. I am writing it in Java and kind of running into a road block as far as writing the data to file in the right byte sequence. Is there an easy way to convert basic types, int and long to a sequence of bytes?

You can use a DataOutputStream created with a ByteArrayOutputStream:

ByteOutputStream baos = new ByteOutputStream();DataOutputStream dos = new DataOutputStream(baos);

Use the writeXXX() method of the DataOutputStream:

dos.writeInt(someInt);dos.writeLong(someLong);

Then use the toByteArray() method of the ByteArrayOutputStream to get the array:

byte[] array = baos.toByteArray();
