Hi, Prashh,

Theoretically you can create array of clusters with booleans (one, or two or three for different bit depth.)

But for achieving best performance, I would like to recommend to use U8 type where only 1 or 2 or 3 bits are used.

For displaying the image you can use Binary Palette, for example, for 1 bit image - with black (zero) and red (1). For two bits you may have only 4 different colors, and so on.

Andrey.

Seems like the most direct way of displaying the array and getting the "bits" out of it would be a 2-D array of buttons....

Hi, Prashh,

I hope, the code given below will explain something:

Not really Andy Warhol artwork, but something similar:

The Block Diagram is so trivial, you can recreate it in 10 min by provided screenshot... 8.6 in attachment.

Hello Andrey

   Thanks for your VI. But, I want to use it for gray scale image.

for example: If I put 0 shift, Image should be displayed with 256 different gray levels.

                                -1-------------------------------------- 128------------------

                                -2---------------------------------------  64-------------------

-3---------------------------------------- 32-----------------

-4---------------------------------------   16-------------------

As you can see in the example above - IT IS grayscale image, just displayed with pseudocolors. Just change 4 colors palette to 4 shades of gray and you will get what you wanted.
