How to convert U32 value obtained from color control of front panel to float(SGL) for use with IMAQ Draw ?.

[Jake]

I am trying to get user color inputs from front panel and use it in IMAQ Draw. I need to draw an oval of a certain color in a background of another color. Both these color values are user input. The problem is IMAQ Draw requires SGL color value and the color controls of front panel give U32. I have tried conversion VI's which hasn't worked. HELP !!!

Jake,

I think the color control can be wired directly to the input, but I am not positive. I don't know of any color conversions that would help.

Make sure your image is a color image. You can't draw colors on a grayscale image.

You might want to consider using overlays, which appear on top of the image but are not part of the image.

Connecting it directly to IMAQ Draw does not work. Neither does convering it explicitly using one of conversion VI's.

Jake,

So what does it do when you connect it directly? Do you get strange colors, or is it a shade of gray, or what? It must do something different when you change your color selection.

If you give me more details I might be able to help more.
