Removes the bulk storage of one or more spectra from the Display shared memory. Using sbind and unbind you can have SpecTcl work with a much larger spectrum storage than the shared memory supports; manually swapping spectra in an out of shared memory.
There are three ways you can refer to spectra:
The name of the spectrum is a text string that you defined when you created the spectrum.
The id of a spectrum is a integer that was assigned to the spectrum by SpecTcl when you created it.
The xid (originally Xamine Id) is a number that indicates the slot in the spectrum directory that was assigned to a spectrum that is already bound to the display shared memory region.
In the synopsis above, the first form of the command allows you to remove one or more spectra from display shared memory. Spectra are identified by their names. This command form does not require any command options.
Using the -id option, you can remove one or more
spectra from the shared memory region by specifying the SpecTcl
ids.
Using the -all option you can remove all spectra
from the shared memory. This option takes no additional parameters.
Finally, the -xid allows you to specify the spectra
to be removed from display shared memory by their xid numbers.
Note that unbind has no deleterious effects on the spectrum or its contents. Storage is allocated outside of shared memory for the spectrum contents and the current contents are copied to that storage. Furthermore, the spectrum continues to increment as before. I simply cannot be displayed from display shared memory. A sufficiently sophisticated displayer could access the spectrum contents via the SpecTcl REST plugin at lower performance, however.
