Image Enhancement Window

This window is used to enhance the display of images. When large images are displayed on a computer screen, many pixels (dots) from the drawing are represented by a single pixel on the screen. For example, an E-size drawing would by 12000 by 9000 pixels. Displayed on a 600 by 450 screen area, that means that each screen pixel would represent 400 pixels (20 by 20). There are three ways to represent the drawing pixels:

That's the theory. The reality is that it's simpler to just try different enhancement techniques and see which one works best. As you change the enhancement options, you will see the drawing display change immediately.

The Image Enhancement Window is invoked from the Main Menu's "Drawing/Image Enhancement..." option.

Note: You can zoom and scroll the drawing while the image enhancement window is displayed.
