Tear off Menus
All DS9 menus can be used as a floating tool palette. To 'tear off'
a menu, select the dashed line which is the first item of each menu. At
this point, the menu will become its own window, which now can be
managed
by the user. Multiple copies of the same menu can be created.
Information Panel
The Information panel displays information about the current data
values. The information displayed is configurable via the preferences.
Panner
The Panner allows the user to view the entire frame, along with the
current viewing bounding box, image cursor, and wcs cursor. To pan the
current frame, click and drag the viewing bounding box.
Magnifier
The Magnifier displays a magnified view of the current mouse cursor
location. The Magnifier cursor outlines the size and orientation of one
pixel, given the current frame zoom and orientation.
Button Control Panel
The Button Control panel provides duplicate menu functionality for ease
of use.
Frames
FITS images are displayed in Frames. Frames may be viewed one at a
time, or all at once in Tile mode. Only one frame is the Current Frame,
as indicated by the Blue Border, while in Tile mode. Most functions act
only on the Current Frame.
Graphs
Horizontal and Vertical graphs are available to display a cut through
the current frame data. While the mouse cursor is in a graph, the
information panel reflects the current data values. Graphs are not
available while in Tile Mode.
Colorbar
The Colorbar displays the current colormap and current bias and
contrast settings.
