LabVIEW
array manupulation
Solved!
From what I can tell, your 8 bit image is already decrypted because each line starts with 255.
I thought you were looking for an algoithm that decrypts an encrypted image. You should atttach an encrypted image so we can play.
Even if I use one of the 8 bit color planes, there is no pixel with 255. All lines end in 254.

Your "present image.png" is again a 24 bit image.

Which picture are you talking about? (You attached so many!)
Why don't you attach a small VI and show us how you read it to get a 255 out of it.
Anyway, here is a draft of two algorithms that would do what I understand to be the task at hand. The array version (top) is probably more efficient.
Here's the 8.0 version to process the U8 2D array (downconverted from 8.5, I hope it worked). Of course you would adjust the "line lenght" to your needs.
Just use the same bookend code as BCL to translate between image and 2D array.
Also make sure to wire the color table between unflatten and flatten pixmap.
(BCL uses way too much code for the core algorithm and does it very inefficiently because the arrays are constantly resized.)
