How to tweak the image

Finding the correct "width"
  1. The correct aspect ration of the image is unknown, since the header of the image is encrypted. So we need to find the correct "width" to decrypt the image.
  2. Let's use an example to explain the process.
  3. The first image will look like this (624 x 78).
  4. As we see a lot of horizontal blank line and the image is very wide, we can consider to decrease the width. Let's try the half: 300
  5. Put 300 as the "width" and press "Recalculate".

  6. We barely see the outline but the image looks like repeating (which is a good sign!). We can see that we have 2 image and half of it. 2.5 - 1 =1.5
    We can try 300 * 1.5; 450 as new width.

  7. In case the image is overflowed like below, we can use the "Offset" to fix it.

  8. Now our image is almost perfect so we can work on the Style.
Styling the image
  1. We found the correct width but there are 2 issues.
    • The image is upside down.
    • The image is shrinked.
  2. The first issues is very easy to fix. Just use FlipY to flip the image vertically.
  3. For the second one, we can use the "Width" and "Height" and hit "Redraw" button to adjust the aspect ration.

    And voila! Our image is done.
