Put the content of the subVI in your VI.

Try the modified VI.

Nice! I had to convert "Waveguide Coordinates" to I16 to properly draw those points

Morover, you have to assign a color only once, so this part may be moved outside the N Loop

Furthermore, you may use the Sub-Vi "Overlay-Images-1_MOD.vi" inline

and parallize the N Loop

thanks everybody for the input!

all your ideas work ... so far altenbach's solution is the fastest one.

i've tested it with a large pattern.

the solution by zou/alexderjuengere took ~1s.

the solution by altenbach took 90ms.

If you know that every picture has exactly one black pixel, maybe doing a comparison to black and then ORing the results might work.

Just blindly writing a pixel is faster than ORing, because ORing requires reading the current value first.
