function of attribute node "palette type - grayscale"

[BluE12]

Hello,

i wanted to ask you, what the function of this attribute node "palette type" (grayscale) is?

It is included in (almost) every VI, created in Vision Assistant.

Please crop your embedded image next time. There is no need to include 1M white pixels!

How old is your LabVIEW version? I think it was in the last century when property nodes were still called attribute nodes.

What happens if you right-click the node and select "help for palette type" or similar?

The function is the mapping of pixel value to "color" on the Imaq display.  Gray scale will map your 8-bit image to 256 shades of gray, and RGB or HSL to colors.  Other settings are binary, temperature or gradiant which use a different color to value mapping.

So, it doesnt change image information? Is it only a setting how (in which colors) to display the image information in the frontpanel?

When I process an rgb image in an VI, this node has no impacts on the processing?

[altenbach]

It's a property of the indicator. It cannot change the incoming Data.

I dont see any difference in an displayed rgb image, when I change from grayscale to rainbow or something else. And I see also no difference in displaying when I erase the node..

So I dont understand this.

Sorry for the big image.

thanks a lot!

Also for correcting me.

I would think it only applies to palettes images. If you have an RGB image, palette settings have no meaning.

Yes palettes only are really useful for 8bit (or 16bit I guess) scaling in imaq displays.  Color images are already color mapped to RGB
