Data Cube / Cube
- sums from equal intervals - A way to sum adjacent slices (adjacent
spectrum channels for spectrial images) and reduce the total number
- running sum - Makes a new data cube where each slice is a sum or
max of neighboring slices. Running sum spectra, running max
spectra, etc. can be made with the Plot menu, without making a new
data cube. Unlike sums from equal intervals, this does not reduce
the number of slices.
- Top hat, quotient, product. New.
- from layers - Use a layers slider. Slices are sums from arbitrary
intervals, indicated by the slider.
- from images - Make a cube from images already opened. (Read
/ as image files loads a cube from individual image files.)
- decimate - extract every nth slice.
- concatenate cubes - make one cube out of two or more cubes, which
you choose in order.
- register using offsets - shifts slices sidewise or vertically with
respect to each other. See offsets button.
- offset pixels using index image. Registration along the depth
(z) axis. For spectral images, this would shift spectra relative
to each other along the energy axis. Uses a registration image,
or map of same dimensions as the cube slices.
- rotate using profile tool. Use the profile tool to indicate
the apparent axis of rotation. This will rotate the entire cube
so that the apparent axis is vertical (or some other indicated direction)
- crop using region - Makes new cube with slices in the range of the
- crop using rectangle - Makes new cube cropped (slice by slice) using
the image rectangle.
- process slices - perform an image processing operation on all slices
and make a new cube. Operations can be selected from here.
- ... (Use <control> key to see documentation on the rest
of these functions.)
- shrink & scale to byte Use <control> key to see
- switch type - Change vector cube to image cube and vsvs. Some
operations work on only one of these types. The PPP
Tool uses the vector cube.
- copy to vector / image cube. Make a new equivalent cube, but
of the other type
- Fresh pixmaps for remaking pixmaps. Occasionally pixmaps may
be damaged, for example if the flicker is left on while you do something
else. This makes fresh pixmaps for all slices, as if reloading
the cube, but without changing any cube data.
