This page gives a brief description of how to use the FIGDISP window for display and analysis of images. The FIGDISP/GUI control window is depicted below.
The following keys are defined:
Key | Function |
---|---|
Z | Zoom in |
a | Go to normal zoom factor |
z | Zoom out |
X | Zoom in X coordinates |
x | Zoom out X coordinates |
Y | Zoom in Y coordinates |
y | Zoom out Y coordinates |
H | Help (display list of key bindings) |
v | Toggle cursor display (Pixel location/ADU's) |
o | Recenter image |
l | Toggle display of panner window (a la SAOimage) |
Q | Quit |
L | Show a window containing the color map |
p | Toggle display of pixel values near the cursor |
r | Produce a row plot in the line graphics window |
P | Print the image |
V | Print the visible portion of the image |
i | Toggle color map inversion |
s | Toggle display of centroid/FWHM window |
c | Produce a column plot in the line graphics window |
comma | Decrease number of pixels averaged for a line plot |
period | Increase number of pixels averaged for a line plot |
slash | Reset number of pixels averaged for a line plot |
! | Toggle function key inhibiting |
< | Decrease number of times LUT entries are recycled |
> | Increase number of times LUT entries are recycled |
? | No longer use LUT entry recycling |
e | Cycle through display scaling algorithms (histogram equalization, autodisp, normal) |
m | Toggle between PAN/COLORS and STAT BOX modes |
S | Print image statistics within box |
All windows except the location window may be resized arbitrarily. The location window can be resized within limits, and the program will often adjust the user defined size. The line graphics window should not be resized while it is being modified.
``p'' or ``s'' pressed in the main window or in the location window will cause the pixel values or seeing window to appear. The window may be dismissed by the same button inside that window. All other functions work from all windows (``Z'' always zooms in).
No transformations (zoom, resize window) will move the point at the center of the window, unless that would cause the entire window to be empty.
