Name that LUT!

[Michael Doube]

Hi all

I'm preparing an old figure for publication and want to add a LUT scale
to it, but I can't find the LUT it was created with.

http://doube.org/images/moduli_map.jpg

I've checked out all the included LUT's and the ones on
http://rsb.info.nih.gov/ij/download/luts/, but nothing seems to fit.

I also can't rip the LUT out of the image since it is RGB (a projection
of a surface map from Kai's 3D surface viewer).

Does anyone recognise the LUT?  Dark blue is low, red is high and I
think there are only 8 or so colours in it.

It goes, dark blue, light blue, white, green, yellow, orange(?), red.

I _think_ it is the good old heat map, sometimes called "physics":

Ciao,

physics.lut is very close, but doesn't have the white band in the middle.

I will keep looking, or just edit physics.lut to about what it should be.

I think that it is closer to the Thermal LUT from the Interactive 3D surface
plot, but that one also has violet...

Hi,

I'm using ImageJ's 3D project stack function to do a 360 degree  
rotation of a 512x512 confocal microscopy stack with 61 vertical  
slices. I choose 360 degree rotation about the y-axis with 5 degree  
increments. When the rotation stack is complete, it has new  
dimensions of 512x524 pixels and not 512x512 pixels. If I do a  
rotation about the x-axis instead, the pixel dimensions come out as  
524x512. Is this a bug? Why are these extra rows or columns of empty  
pixels being created by this function?

Think of Pythagoras here...

You're working with a cube.  3D project shows you the whole cube from
all angles projected.

Yes!

That is it, thanks Gabriel!

If anyone is interested I have generated an ImageJ LUT "thermal.lut"
from the code in the surface viewer plugin.
