The XImtool control panel is the main interface for the XImtool display program, on which SAOtng is based. The SAOtng GUI duplicates the most of the functionality of the control panel in its menu and accel buttons, but the control panel is offered as a window-based alternative to run-of-the-mill menus.
The Frame box will list the frame buffers you currently have defined. Currently, only frames 1-4 are listed.
The text display window gives the field X,Y center, X,Y scale factors, and the X,Y zoom factors. The scale factor and the zoom factor will be the same unless autoscale is enabled (IRAF tv/display only). The scale is in units of display pixels per frame buffer pixel, and is an absolute measure.
The numbers in the Zoom box are zoom factors. Black numbers zoom, white numbers dezoom. The Zoom In and Zoom Out buttons are used to change the zoom by factors of 2. The Center button re-centers the image without changing the zoom factor. Toggle Zoom toggles between the current zoom/center values, and the unzoomed image.
Aspect recomputes the view so that the aspect ratio is 1.0.
Flip X and Flip Y flip the frame.
Clear destroys the current image and erases the frame.
Fit Frame makes the display window the same size as the frame buffer. In general, this means that the display window can be resized smaller than the 512x512 space it occupies in the overall SAOtng window, but it cannot become larger. To make it larger, use the resize capabilities of your window manager.
At the top is a scrolled list of all the available colormaps. Click on the one you want to load it.
The three sliders adjust the contrast (upper slider), brightness (middle slider), and max contrast (lower slider) of the display.
The Invert button inverts the colormap (multiples the contrast by -1.0).
NOTE: you can blink no matter what ximtool options are in effect, but many of these will slow blink down. To get the fastest blink you may want to turn off the panner and coords box, and match the LUTs of all the blink frames. All the ximtool controls are fully active during blink mode, plus you can load frames etc.
Display WCS coordinates and pixel value as the mouse is moved across the image. This duplicates the function of the WCS window on the image itself and is made available for cases where you do not want to clutter the image with the WCS display. Note that this window is selectable so that you can cut and paste the current WCS display values.
