Display Window Help

Description: The Display Window contains a full resolution image of the corresponding band data. It also provides image display functions on the displayed image as well as on the associated raw or geophysical data.

Note: There is no hard-coded limit to the number of display windows open at one time. The only limit is the memory of your machine.



Informational Items:
Window Title The window title contains the window number and the name of the band data that is loaded into it.

Action Items:

Window Resizing The window containing the full-resolution image can be resized at any time by holding down the first mouse button and dragging the corners of the widget.
Window Scrolling The full resolution image can be scrolled in either the x-direction or the y-direction by using the scroll bars.
Functions  Pressing the Functions button shows a list of functions that can be performed on the currently displayed image.  For functions which require many possible input parameters (such as Grid and Coastline), selecting the function from the function menu will cause the function to be performed with default values. To modify these default values, use the Setups Menu button.
Rescale Bring up Display Scaling Setup GUI to allow modifying scaling options for redisplay.
