binary image to color jpeg

[juanni]

I am manipulating (B/W) ICCD images with Vision.  Unfortunately, I have to cut the images down to I8, but that is not the issue.  My question is this-  Labview allows me to visualize the I8 data with a "rainbow" color map.  I would like to get it to automatically create a color JPEG file (or other image file type) that I can open in powerpoint.  I am aware of the IMAQ write file2.vi, but that only writes a grayscale file.  How do I go about interpreting the I8 values to color data?  Sorry, I am a newbie to image manipulation.  J

Use something like this.  Fill in the array constant with the colors that you want.

I'm using labview 11.0 (sorry, I know that I am supposed to include this in my post).  Could you save the vi for an earlier version or post a picture of the back panel?  Thanks.  J

Here.

Thanks. Are you aware of any way to programmatically fill in the color array?  The IMAQ getpallete.vi doesn't seem to do it.  J

Sure.  You can create the array programatically.  How you would code it depends upon what you want the array to be.

You would probably make use of this:  Functions -> Programming -> Graphics and Sound -> Picture Functions -> RGB to Color.vi
