Selecting Display Options The Display Options window opens when you click on the Display Options... button in the Open window. The paper size you select will override any format information stored in the file you wish to display. New settings apply only to the next input file you display. The appearance of the currently displayed file, if one exists, does not change. In the Display Options window, do the following: 1. In the Default Paper Size list box, click on one of the paper sizes. 2. In the Width and Height entry boxes, you can optionally specify paper size values other than the default paper sizes. 3. Click on the characters, inches, or mm (millimeters) radio button to specify the unit of measurement for the width and height values you entered. The characters unit corresponds to the size of a character in the 12-point Courier font, which is the CDA Viewer's default font and which is also very close to the standard font used by most printers. In 12-point Courier, and in the character unit as interpreted by the CDA Viewer, there are 10 columns per inch (0.1 inch per character horizontally) and 6 rows per inch (0.167 inch per character vertically). 4. Click on the Override Document Format button to apply the default paper size or width and height values you selected. 5. Click on the OK button to complete selection of the paper size . 6. Click on the Cancel button to cancel the Display Options window. For information related to selecting a paper size , double click on an item from the list of additional topics below.
