Question

I would like to convert an instance of Bitmapto an instance of ByteArrayin order to be able to pass it to a Webservice.

Right now, what I’m doing is:

ByteArrayOutputStream bos = new ByteArrayOutputStream();
bitmap.compress(CompressFormat.JPEG, 100, bos);  
byte[] imageData = bos.toByteArray();
ByteArrayBody byteArrayBody = new ByteArrayBody(imageData, imagePath);

The problem here, is that I am using compression to make it happen, and this results in lowering the quality of the bitmap.

Is there any other way to do this?

Thanks!

EDIT:
I can’t compress to PNG, since the server uses JPEG.

Answer 1

• As Sean Owen said, use png rather than jpeg.
• You can get an int array with getPixels().
• You can get a buffer object with copyPixelsToBuffer(), which you
  can later convert to a byte[].

In any case png compression is the best solution as it does not need as many intermediary operations and gives a compressed result.
