Question

I need to encode an image to be JPEG and maximum file zise to be 300 K and send it as byte array. I make encoding :

ByteArrayOutputStream baos = new ByteArrayOutputStream();
bitmap.compress(Bitmap.CompressFormat.JPEG, 100, baos);
image = baos.toByteArray();

do you know how to limit the file size to 300K? maybe the solution is to make image quality lower, but sometimes(when the image is smaller) I may not need this. Thanks

Answer 1

By repeatedly compressing with descending ‘quality’ values until the resulting byte[] length <= 300KB. There is no shortcut through this (AFAIK) but you can choose the quality values carefully and limit yourself to, say, a maximum of 4 compressions.
