If the user desires to decrease the size of the bins, simply click the Inc Bins
button and the bins divide in half both vertically and horizontally, creating 4 bins
out of each existing bin. Bin size decreases when the program collects the next
data point, and previously plotted points will be re-plotted with respect to the
new bin size. If the Pointing Stability program is paused, the change will not
take place until the program is restarted and the next data point is collected.
2.2.11 Create Palette…
Select this option to design a custom beam display color palette. We have also
included a sample set of palettes as bases from which new palettes can be
derived.
The Spiricon Palette Generation program can also be launched independently
from c:\Spiricon\LBA-USB\PALETTEGEN2.EXE.
The program is very easy to use once a few concepts are understood.
Upon opening, the two horizontal color bars appear blank, or black. Create a new
palette by placing seed colors into the upper bar and observing the resulting
palette in the lower bar. Colors on the left represent low intensities while colors
on the right represent high intensities.
The upper bar contains entries for 128 individual colors, numbered from 0 on the
left to 127 on the right. To create a palette, define at least 2 colors or as many
as 128 to make use of all possible colors. LBA-USB uses a 128 color palette to
describe all beam display images.
