  Anyhow, I'm developing for android.
  The question is I have images in png format (or jpg as bmp is quite large for my app).
  How can I combine three images from top to bottom.
  I do not need to save them on sd just to display them.
  Thanks, and sorry if a similar question with answer exists.</p>
