Thanks for both of you alexderjuengere and GerdW for answering me 😄

I've tried the VI of alexderjuengere in a pc with LabVIEW 2012 and that's what I really want , it's the perfect solution 🙂

THANKS for all of you 🙂

I have to admit, GerdW's approach is much more generic because in his approach you're in immediate command of the image depth; my approach always use 24 bit image depth ...

oh, and - as I've just checked - you needn't to divide by two

I'm sorry alexderjuengere but I didn't understand why in your approach we are limited to 24 bit image depth

[salah_m7]

Oups xD now I see why. (I'm sorry but this is my first time to deal with pictures in LabVIEW)

And for GerdW: your VI also worked for me :), but the first time it didn't work well because it was my fault I haven't understood your comment clearly but I've changed the values of the constant clusters and finally I've got what I need, thank you very much 😉

Thanks LabVIEW community 😄

ok, I didn't express myself clearly.

we are not limited to 24 bits, but it is not that comfortable to switch to a different resolution.

what I really wanted to point out is that I used a u32 (r, g, b, alpha a 8 bits * 4 = 32 bits) to represent a binary image (true, false a 1 bit).

From my idealistic point of view I would rather prefer somthing like this

Can you explain the "=true"? What would happen if you leave it out? 😄

[altenbach]

Here's what I would do. (Simple problems ask for complex math! :D)

Note that the origin is in the upper left corner and Y is positive going down. Modify as needed.
