Computer programs which allow one to simulate high resolution electron microscopy images generally deliver the output on a line printer with the overprinting technique. Although this method suffers from poor resolution and limited contrast dynamics, it is still in widespread use. A more effective way is to represent the images in digital form on a color video display, and several solutions have been proposed recently, which often, however, make necessary use of rather expensive pictorial video terminals. In this work we describe a simple program which allows one to represent the output of a multislice program (projected potentials, lattice images, and diffraction patterns) on the display of an inexpensive color video terminal. Useful operations on the image, such as color selection over a wide range, image magnification, and filtering (to enhance specific details of interest) have been implemented. The displayed …
