12. Viewing and Editing 
Images
This chapter describes the viewing tools for magnifying and optimizing your 
images. This chapter also describes the tools for cropping, flipping, and 
rotating images, reducing background intensity and filtering noise, and 
adding text overlays to images.
These tools are located on the View, Image, and Edit menus.
Note: The following chapters contain instructions for analyzing X-ray films, wet 
and dry gels, blots, and photographs. For the sake of simplicity, these are 
all referred to as “gels.”
12.1 Magnifying and Positioning Tools
The magnifying and positioning tools are located on the View menu and 
Window menu; some of these functions are also found on the main toolbar.
These commands will only change how the image is displayed on your 
computer screen. They will not change the underlying data.
