Color scale bar and result window

[Breukers, C (TNW)]

Dear All,
 
I wondered if there is somekind of color scale bar available for RGB
images.
A kind of legend where color is linked to their intensity value.
 
I know that it is possible for LabVIEW and Matlab.
 
And secondly is it possible to get/copy data from other ''window'' then
the standard Result window?
We use a correlation plugin, which has its own result window. Ideally we
would like to combine these two.
 
Regards,
Christian Breukers

This depends somewhat on what you really want.  Are you measuring
"intensity" at several wavelengths, or are you combining the
measurement into one.  If you want an average intensity, you might
consider converting your rgb images into 8-bit.  Then you can use one
of the LUTs as a color scale bar.  You can create a new image and
fill it with a greyscale ramp, and then apply, say, the spectrum lut
to get color representation of grey scale values.

Hi Christian,

maybe it is pseudo-color images that you talk about?

Pseudo color is a grayscale image with a color lookup table.
There you can easily have a color scale bar using
   Analyze>Tools>Calibration Bar.
You can use Analyze>Calibrate to set custom calibration and
units.

You can't paste into the Results window; you have to use a text
window or external spreadsheet program for that.

You can write a macro to access the main Results table, both
for reading and writing (see getResult, setResult). So, if
you want to do some programming, you could write a macro
that gets the contents of the clipboard by the String.paste
function and then puts it into the main Results table.

If you want to have colors for interpreting better your grey-scaled image you can find the color scale converter directly on the imageJ toolbar:
->LUT Menu-> LUT -> 16_Colors

there are other scales as well there... Hope you will find the color scale you like :)

Cheers

Dear Michael,
I encountered a similar question. I have a 32-bit image, whose intensity is from 0 to 0.27. I have set a LUT and Calibration bar, but I do want to get the bar from 0 to 0.5, not the max of intensity. And I found Analyze->Calibrate cannot  help. Do you have any ideas? I will really appreciate your help.

Dear Michael,
Please forget about the question. I know the answer now: just set the range firstly in Image->Adjust->Brightness/Contrast. Sorry for interrupt.
