=TITLE Overview
=TITLE Overview of the CDA Viewer
=KEYWORD Overview
 The CDA Viewer lets you look at Compound Document
 Architecture (CDA) files on your screen. The default
 file format for the CDA Viewer is Digital Document
 Interchange Format (DDIF).

 DDIF is a standard format for the storage and
 interchange of compound documents. Compound documents
 contain multiple elements, for example, text and
 graphics.

 The CDA Viewer displays only files that are in DDIF
 format. You can display a file that is not in DDIF
 format if a DDIF converter exists for the file's
 format. The CDA Viewer converts the file to DDIF format
 before the file is displayed.

 The CDA Viewer can also display PostScript files when
 running to displays with servers containing the Display
 PostScript Extension. To view a PostScript file,
 specify PS as your format when opening a PostScript
 document.

 For more information about using the CDA Viewer, double
 click on an item from the list of additional topics
 below.

 For information about using help, choose an item from
 the Using Help menu above.

 For more information about displaying PostScript files,
 double click on an item from the list of additional
 topics below.

Additional information available:

scale factororientationuse commentsuse bitmapsuse faketrayswatch progress

=TITLE scale_factor
=TITLE Scale Factor
=KEYWORD PostScript
 The Scale Factor lets you scale the page display
 size of your PostScript file. The number you select
 indicates whether the CDA Viewer will shrink or enlarge
 the page display.

 If the scale factor is less than 1.0, the page display
 will shrink. If the number is greater than 1.0, the
 page will expand. You can specify a scale factor in
 the range of 0.1 to 4.0 the size of the original page
 display. By default, the scale factor is 1.0.

=TITLE orientation
=TITLE Orientation
=KEYWORD PostScript
 The Orientation radio box lets you select the
 orientation for displaying PostScript files. By
 default, the CDA Viewer displays files in the same
 portrait or landscape mode in which they were created.

 Use the Orientation radio box to select different
 orientations to view files in reverse landscape mode
 or upside down.

=TITLE use_comments
=TITLE Use Comments
=KEYWORD PostScript
 Click on the Use Comments button to allow the viewer to
 interpret comments in a file as a means of moving from
 one page to any other page in that file more quickly.

 The Use Comments option is in effect by default. This
 is indicated by the highlighted Use Comments toggle
 button.

 If you try to view a file but receive an error message,
 you might be able to correct the problem by disabling
 the Use Comments option and reopening the file.

=TITLE use_bitmaps
=TITLE Use Bitmap Widths
=KEYWORD PostScript
 The same PostScript file can be either printed or
 viewed on the screen, but characters look somewhat
 different on the printed page and the screen. The
 printer has finer resolution than the screen; with
 more dots per inch, the printer can make characters
 look clearer than the screen can. However, to clarify
 characters, the CDA Viewer can use spacing formulas
 designed for bitmaps (screen images) instead of those
 designed for print.

 The Use Bitmap Widths option is disabled by default.
 This setting is appropriate if you are more concerned
 with format and layout and less concerned with reading
 actual text. Spacing between characters is the same
 as on the printed page, so the page layout is also the
 same. Note however, that characters might be dense and
 difficult to read.

 To get a better view of the text in a file, click on
 the Use Bitmap Widths option. The next time you open
 a PostScript file, Bitmap Widths will be used. Text
 characters will appear well spaced and are easily read.
 However, the file might look slightly different on
 screen than it would when printed. Columns may not be
 aligned precisely or a paragraph formatted for right
 justification might appear instead with a ragged right
 margin.

=TITLE use_faketrays
=TITLE Use Fake Trays
=KEYWORD PostScript
 Choose the Use Fake Trays option to view a file that
 contains tray size directives.

 Some PostScript files contain tray size directives,
 that is, instructions that tell the printer what tray
 size to use. The CDA Viewer displays a diagnostic error
 message if you try to display a file that contains tray
 size directives.

 To view a file that contains tray size directives,
 click on the Use Fake Trays toggle button, and reopen
 the file.

=TITLE watch_progress
=TITLE Watch Progress
=KEYWORD PostScript
 Choose the Watch Progress option to view a file while
 it is being displayed in the CDA Viewer window.

 This allows you to view a page as it is being
 calculated, rather than waiting to display the whole
 page at one time.
