Intensity Profiles

This Tool plots profiles for gray level images, RGB images and data cubes. 

Averaged profile for better signal-to-noise:

Profile without averaging (width = 0) does not show the thin lines as above.  They are obscured by noise.

Composite RGB Profile:

 

The SRM484 image is in the lx-images folder and is distributed with Lispix.

Note for highly zoomed images:

When images are zoomed up enough to see the individual pixels, a cyan line appears parallel to the profile tool line, and running through the pixel centers rather than the upper left corner.  (new 3/20/07).

Ideally, the tool itself should be where the cyan line is, but this would require extensive re-programming.
