DESCRIPTION
The hdsview program provides a Motif user interface for the
hdsscript interpreter. Hdsview and hdsscript function as two
cooperating programs. Hdsview creates the viewing window and hdsscript
draws in it.
Don't be alarmed by the number of options. Generally, one
invokes hdsview with just one parameter, the name of the file to be
previewed. If the filename is ``-'', hdsview will read from ``stdin''.
The options provide a way to set X resources from the command line for
a single invocation of hdsview. For that reason, discussion of the
options is delayed until after the X resources are discussed.
MAIN WINDOW
The main viewport is on the right side of the main window.
There are scroll bars along the bottom and right edges of the viewport.
To the left of the viewport is the table of contents. If the PostScript
file has document structuring convention (DSC) comments, the table of
contents will display the page labels (i.e. usually page numbers). At
the top of the application is the menu bar, consisting of push buttons.
Each push button brings up a pulldown menu. Over the table of contents
there is one optional label that contains the locator. The locator shows
the location of the cursor in the viewport. The location is expressed
in the default user coordinate system. The locator is useful for
measuring bounding boxes.
Within the main viewport the mouse cursor is a ``target'' when
hdsscript is doing work. The cursor is a ``crosshair'' when hdsscript
is idle. When moving to another page in a document, it is generally
best to wait for hdsscript to become idle. Otherwise, the current
hdsscript process must be killed and the overhead of reading the
prologue is incurred again.
Clicking anywhere within the viewport will popup a zoom
window. The window is centered about the location that was clicked.
Clicking with the first mouse button pops up a low resolution zoom
window. Clicking with the second mouse button pops up a medium
resolution zoom window. Clicking with the third mouse button pops up a
high resolution zoom window. The cursor in the zoom window will display
a ``target'' or ``cross hair'' depending on the state of hdsscript. The
locator reports the position of the cursor in the zoom windows as well
as the main viewport.
In the table of contents, the first and third mouse button
functions exactly as they do in a Text widget. That is the first mouse
button selects text and the third mouse button extends selections.
However, clicking on a page label with the second mouse button will
cause that page to be shown. The page being displayed is marked with a
`<` in the right margin of the table of contents.
POPUP WINDOWS
The are several additional windows that may appear. The copyright
window will appear whenever copyright information is requested. The
information window appears whenever the hdsscript process writes to
``stdout'' or ``stderr''. Whenever there is an error in the PostScript
program, the stack trace will appear in this window. When hdsscript is
invoked without the quiet option, informational message regarding the
state of hdsscript will appear in the information window. The copyright
and information windows can be dismissed by pushing the ``Dismiss''
button.
MENUS
There are six buttons on the menu bar. They are the File, Page,
Magstep, Orientation, Media, and Help buttons. There are keyboard
accelerators for most of the menu items. Be sure to read the keyboard
accelerator section.
File
This popup menu controls file access:
Open...
Pops up a dialog widget to ask for the file name. The widget is in
total control until it pops down. Opens the file for viewing.
Reopen
Reopens the current file.
Print...
Pops up a dialog widget to ask for the printer name. Sends the
whole document to the printer.
Print marked pages...
Pops up a dialog widget to ask for the printer name. Sends the
marked pages to the printer. If no pages have been marked, the mark
procedure is called before printing and the unmark procedure is called
after printing.
Save marked pages...
Pops up a dialog widget to ask for the file name. Saves the marked
pages in the selected file. If no pages have been marked, the mark
procedure is called before saving and the unmark procedure is called
after saving.
Copyright...
Pops up the copyright window.
Quit
Causes hdsview to exit.
Page
This popup menu controls page access:
Next
Display the next page.
Redisplay
Display the current page.
Previous
Display the previous page.
Center
Center the page in the viewport.
Mark
Mark the pages that have been selected in the table of
contents. If no pages have been selected, mark the current page.
Unmark
Unmark the pages that have been selected in the table of
contents. If no pages have been selected, unmark the current page.
Magstep
The Magstep menu controls the magnification at which the document
is viewed. The default magstep of 0 implies no magnification (i.e. the
size on the screen should match the size on paper). Hdsview borrows the
notion of magstep from TeX. The magnification is defined to be
1.2**magstep. At magstep 1, the document is magnified by 1.2. At
magstep -1, the document is reduced by 1.2. The Magstep menu lists
values from -5 to 5.
Orientation
The Orientation menu controls the display orientation. A
``diamond'' appears in front of the current orientation.
Portrait
Set the orientation to Portrait. This implies no rotation. A
portrait orientation indicates that the longest edge of the paper is
parallel to the vertical (y) axis.
Landscape
Set the orientation to Landscape. This implies a clockwise
rotation of the paper by 90 degrees. A landscape orientation indicates
that the longest edge of the paper is parallel to the horizontal (x)
axis.
Upside-down
Set the orientation to Upside-Down.
Seascape
Set the orientation to Seascape. This implies a
counterclockwise rotation of the paper by 90 degrees.
Swap Landscape
Swap the meaning of Landscape and Seascape, since some
documents need to be rotated the other way. The swap landscape button
allows hdsview to automatically rotate the document the right way in
response to the %%Orientation comment in the PostScript file.
Media
The entries on the Media menu set the page media. Media defined
in the document appear at the beginning of the menu separated by a line
from the standard media. A ``diamond'' appears in front of the current
media.
Here are the standard media names and their sizes. The size is
given as the width and height in PostScript points.

HDSVIEW WIDGET RESOURCES
Certain resources in the hdsview widget may be set by the user.
These selected resources are presented below.
busyCursor (class Cursor)
The cursor shown when hdsscript is rendering to the window. The
busy cursor is set to the ``target'' by the application defaults.
cursor (class Cursor)
The cursor shown when hdsscript is idle. The default cursor is
the ``crosshair''.
interpreter (class Interpreter)

is convenient to set this resource to the path of an alternate version
of hdsscript for testing. The default value is ``hdsscript''.
preload (class Preload)
Files to load before the PostScript program. It is convenient
to name files that preload fonts here for PostScript programs that
continually reload fonts while rendering a page. The default is to not
preload any files.
quiet (class Quiet)
Tells hdsscript whether to produce informational messages. The
default value is ``false''.
useBackingPixmap (class UseBackingPixmap)
Tells whether to use a backing pixmap. If this resource is
false, backing store is requested on the hdsview window. Some X servers
have limited resources for large pixmaps. Also, some X servers' backing
store is much faster than using a backing pixmap. You should reset this
resource if your X server is one of the server types mentioned. The
default value is ``true''.
xdpi (class Resolution)
Sets the X resolution of the window in dots per inch. You can
use this resource to affect the main window. Zoom windows have their X
dpi set explicitly in the program. The default value is calculated from
the screen metrics.
ydpi (class Resolution)
Sets the Y resolution of the window in dots per inch. You can use
this resource to affect the main window. Zoom windows have their Y dpi
set explicitly in the program. The default value is calculated from the
screen metrics.
HDSVIEW WIDGET ACTIONS
notify(width height xdpi ydpi)
The notify event is used by the hdsview application for the
locator and popup zoom windows. If the width and height are 0, the
event is used for the locator. Otherwise, it triggers a popup zoom
window. The default width and height are 72. The default xdpi and ydpi
are 300. The height will default to the width if the height is omitted.
The ydpi will default to the xdpi if the ydpi is omitted.

LIMITATIONS
If the document does not begin with ``%!PS-Adobe-'', it does
not claim conformance to the document structuring convention. When these
documents are encountered, the functionality of hdsview is limited to
giving you scroll bars and a next page capability. Because there is no
table of contents, skipping around the document and marking pages is
impossible.
If there is no table of contents for the document, the popup
zoom window will always show the first page.
There is no visual indication of when an orientation or media
is being ``forced''.
The NFS file access protocol must be used to view remote
multiple page documents. There is no support for local printing. Remote
printing works only when hdsview has been started by rshing from a
remote host. Saving the document to a file is not supported. The
zoomview window does not popup under the cursor as it should.
BUGS
Please report all bugs to Technical Support at HDS Network
Systems, Inc. Bug reports can be e-mailed to support@hds.com. Be sure
to include the hdsview version and the ViewStation server code release
version in the bug report.
