Manipulating an image file, four pixels at a time.|
Pixel by Pixel
The password you want is hidden in the image above. The password is case-sensitive and contains numbers.
To make it appear, you will need to take all pixels in the image, 4 by 4, splitting each 2x2 block into the 4 corners,
in parallel, as illustrated on the image above for 2 such blocks in a 12x8 image.
No pixel will be lost in the transformation and the new image will be a juxtaposition of four reduced versions of the original image.
If everything goes fine, you should see the password appear... after 500,000,000 repeats of the complete transformation!
Hint: Before you reach 10 repeats however, you should see something "happening" with the image. This has nothing to do with the password, but might make your journey shorter than expected!
