How to replace a specific color with transparent color?

[sqrt(-1)]

I would need to get image of a control but I'd like to replace the background color of the control with transparent color (like the commentest image editor).

I cannot use IMAQ library, so I would like to use 2D-picture palette.

I can read the image data pixel per pixer, but.. once the color to be replaced is found, how to replace it with transparent?

Thanks all

It sounds like you want the "Create Mask.vi". If not, you might want to provide some code that shows what kind of situation you're dealing with.

Thanks, I've used Create Mask and it works. I never used it before.

Thanks a lot
