Hi all,
There's a palette option where you can create an 8-bit greyscale image into different "color maps". The same can be done prgramatically using property node.
Now, I need either a "gradient" or "rainbow" type palette where I can set a range of colors to be mapped.
For example I want the image below
to look something like this,
the above image takes shades from red to green. Any help is appreciated.

Can you fix broken link?

Attached is a LabVIEW library where I mapped all of the MATLAB options for color palettes. See if one of these works. I don't remember what all of them look like. I believe this copy is from LV 2011.

Thanks a lot for the sharing of these color palettes and the tester VI with an Intensity Graph and an Image Control, rpursley8

It's helpfull !
I am curious to know where do you find or how do you calculate the 256 values of RGB U32 for each palette.
I am searching the color table of 256 values corresponding to the Red (Positive) Blue (Negative) colormap (like the sreenshot)
Could you help me to build the colors table please ?

I have found.
It's easy to add new color map to the .lvlib shared by Randall by downloading the color tables on a website like this : Color table gallery
For instance, the files with the extension .rgb contains the 256 values of the colormap that I searched : RGB table of "CoolWarm" table

This will generate the color map you want

Make sure when you add that new class for this color map that you do 'Make Current Value Default' once you put the values in the class control.
