negative of a color image

[fredni]

Hi,
I have a color image and I want to take the negative of this image (black turns to white, red to green, and so on...). Is there an in-built vi in LV to perform this task?
Thanks a lot.

Hi Fredni,
I don't know a VI that inverts all the color planes at once.
Of course, inverting each plane individually is supported, see IMAQ Inverse.

Hi,
you can use the image to array function and manipulate the 32 bits RGB data as you want.

Very good proposal, Manuel.
This is more flexible. Especially as IMAQ Inverse will not convert red to green.
Have a successful day, Guenter
