Sometimes you need to make adjustments to the image to suit your purposes. Some of these adjustments may be as simple as zooming in or out and some may be as complex as changing the color scale or the way the pixels are scaled on the image. All of the tools you need are located directly above the Thumbnail and Detailed Aspects. There are also a set of functions that can be launched via this menu bar. These functions are instrument dependent. The menu below is for LMI.
Color
This provides a drop-down menu of available color maps that can be used as well as an invert-color option. The list and the RGB values were copied from IDL. The default is linear grey scale.
Image Zoom
The 4 controls with the magnifying glass allow you to control the ratio of the image to what is displayed.

The third magnifying glass from the left will reset the ratio back to 1:1 and the last magnifying glass will fit the image to the client area.
