Combine
Combine accepts up to three data bases and builds data set that are
algebraic combinations of them. The three data bases are called "A," "B,"
and "C." Some simple combinations of the databases can be selected with
the Function menu; more complex and much more general combinations can
be created using the
Calculator application.
Combine will allow the exporting of its produced data sets via the drag
and drop button.
Combine functions on one slice of each of its three input data sets;
its output is two-dimensional. Sliders can be
used to select these slices; they can be different slices from the same
data set, which can be quite useful.
Controls
Buttons
The Histogram button adds (or removes) a Histogram
from the application window.
Magnify and Minify change the size of the displayed image.
The Calculator button launches a Calculator
application, which is automatically linked into Combine.
Menus
The main menu controls the location of the crosshair and bounding box,
which are very similar to Image's; see Image
for more details.
The Function menu allows one to select between several standard combinations
of the data. Those are
-
A: Display the first data set.
-
B: Display the second data set.
-
C: Display the third data set.
-
A/B: Display the result of this computation.
-
A-B: Display the result of this computation.
-
(A-B)/C: Display the result of this computation.
-
(A-B)/(A+B): Display the result of this computation.
-
rgb: Display data set A as red, B as green, and G as blue.
-
calculator: Display the results of the calculator's calculation,
if any.
The Palette menu allows one to choose between the palettes of the three
data sets or one unique to Combine. It's a red-to-grey-to-blue ramp set.
The Color tool can be used to supersede this
choice.
Applications to Link to This Application
Any Data Object may be linked via the "drag
'n drop" button to this application.
Color is useful to select alternative color
palettes.
Sliders pick slices of the data sets dropped
in. If more than one of A, B, and C represent the same data set, a single
slider linked from it to Combine will adjust all the slice levels. If,
however, more than one slider is linked in, then
each slider controls each data base level independently.
Crosshairs or bounding boxes on other applications linked into Combine
will control Combine's crosshair or bounding box.
The Calculator is normally linked into Combine
to
do most calculations.
Histogram can be linked in to control color
palettes.
Applications to Link This Application to
Combine's crosshair and bounding box can
be used just as Image's can; see Image
for more details on how to use those tools.
