I want to get a confirmation of what the final resolution should be after joining two pictures horizontally.

I have two pictures A and B which have resolutions 100x100 and 100x100, respectively, for the height and width. I joined the images.

  • Output shows correctly, Image B at the end of the Image A. However, the resolution of join A-B picture is 200x400.

  • If I iterate once more for two A-B-s, I get 400x1600.

So each join increases the height resolution and width resolution 2x and 4x, respectively.

This causes problems for me. Any idea what's going on here?

    If each image is 100 x 100, output of AB should be 100 x 200. Output of ABAB should be 100 x 400. Am I missing something? Can you post images of what you're specifically talking about? – Tim Troiano Sep 29 '16 at 20:29
