You move any color band in any of the sliders by dragging the left, right
or middle portion of the band. Dragging the middle of the band moves
the band without changing its length.
A slider will snap to and work on the front image, unless
the Slider /Lock to Image, No Jump command is used:
When the cursor enters the slider, it switches to the front
image window and moves underneath it. The title bar of the slider
will change to show the new window when a slider band is moved..
When locked, the above does not take place - the slider
remains working on its current window, and remains in whatever position
you have placed it.
More than one slider can work on one image at the same time. What
the image looks like depends on which slider band was last changed.
A slider can work on more than one image simultaneously, using groups.
(Group Tool, note
on groups of windows).
Threshold Slider
The threshold slider is used for making masks from gray
level images. Areas of interest selected by the slider are shown in
red. The resulting mask (which you may not choose to display
using the Thresholds button in the slider, but which Lispix uses internally)
gives the corresponding red pixels the value of 1 in the mask. Elsewhere
the mask is zero.

This example shows a real valued image. The values range
from 0 to 0.46 - use Info / Sizes & Limits. The pixel values
between 0.1337 and 0.3665 are shown in red.
The red band covers 44% of the range of the pixel values.
The percentage of image pixels that are red or selected is 5.33. |
