DESCRIPTION
The gvu program provides an X11 user interface for the
ghostscript interpreter. gvu and ghostscript function as
two cooperating programs. gvu creates the viewing window
and ghostscript draws in it.
Don't be alarmed by the number of options. Generally, one
invokes gvu with just one parameter, the name of the file
to be previewed. If the filename is ``-'', gvu will read
from ``stdin''. The options provide a way to set X
resources from the command line for a single invocation of
gvu. 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.
If the page is larger than the viewport, there will be
scroll bars along the bottom and right edges of the view-
port. To the left of the viewport is the table of con-
tents. If the PostScript file has document structuring
convention (DSC) comments, the table of context will dis-
play the page labels (i.e. usually page numbers). To the
left of the table of contents is the menu box. Each push
button brings up a popup menu. Over the menu box and
table of contents there are three optional labels that
contain the title, date, and locator. The title label
contains the document title found in the DSC comments. If
no title can be found, the filename is used in its place.
The date label contains the document date found in the DSC
comments. If no date can be found, the last modified date
of the file is used in its place. Since the title and
date labels may be clipped by the main viewport, the date
and title labels are push buttons that bring up a popup
window with the title or date. These popup windows also
show the ``document'' icon when the displayed string comes
from the DSC comments. 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 ghostscript is doing work. The cursor is a ``cross
hair'' when ghostscript is idle. When moving to another
page in a document, it is generally best to wait for
ghostscript to become idle. Otherwise, the current
ghostscript process must be killed and the overhead of
reading the prologue is incurred again.
Gvu will check to see if the file has been modified just
before it displays a page or when the application is
deiconified. If the file has changed, it will reopen the
file.
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 reso-
lution zoom window. The cursor in the zoom window will
display a ``target'' or ``cross hair'' depending on the
state of ghostscript. The locator reports the position of
the cursor in the zoom windows as well as the main view-
port.
In the table of contents, the first and third mouse button
function 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
There are several additional windows that may appear. The
copyright window will appear whenever copyright informa-
tion is requested. The information window appears when-
ever the ghostscript process writes to ``stdout'' or
``stderr''. Whenever there is an error in the PostScript
program, the stack trace will appear in this window. When
ghostscript is invoked without the quiet option, informa-
tional message regarding the state of ghostscript will
appear in the information window. The copyright and
information windows can be dismissed by pushing the ``Dis-
miss'' button.
The Select File dialog widget will appear when you wish to
open or save a file. The Select File dialog widget allows
an X11 user to select a file by typing the path or by
browsing in directory listings and selecting entries with
the mouse.
All the usual key
bindings can be used in the text widget, except for Return
and Control-M, which are equivalent to pressing the OK
button. The path can be scrolled using the large horizon-
tal scroll bar, or by moving the insertion cursor in the
text widget. The directory entries can be scrolled using
the vertical scroll bars, or by holding a mouse button
down and moving out of the listing. The scrolling speed
varies with the distance from the listing.
The directory entries are terminated with special charac-
ters that show the type of entry, similar to the -F option
of ls(1).
The Select File dialog widget is in total control until is
pops down. No other controls in gvu will be active during
this time.
MENUS
There are five buttons in the menu box. They are the
File, Page, Magstep, Orientation, and Media buttons.
There are keyboard accelerators for most of the popup
menus. Be sure to read the keyboard accelerator section.
- File
- This popup menu controls file access:
- Open...
- Pops up the Select File window in
preparation to open a file. The
Select File 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 docu-
ment 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 then the unmark
procedure is called after printing.
- Save marked pages...
- Pops up the Select File window in
preparation to save a file. The
Select File widget is in total control
until it pops down. Saves the marked
pages in the selected file. If no
pages have been marked, the mark
procedure is called before saving and
then the unmark procedure is called
after saving.
- Copyright...
- Pops up the copyright window.
- Quit
- Causes gvu 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 mag-
step of 0 implies no magnification (i.e. the
size on the screen should match the size on
paper). Gvu 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 val-
ues from -5 to 5.
Orientation
The Orientation menu controls the display orien-
tation. A ``dot'' appears in front of the cur-
rent orientation. The first mouse button sets
the default orientation. The DSC comments may
specify an orientation of Portrait or Landscape
that overrides the default. In this case, a
"document" appears in front of the current ori-
entation. The second mouse button can be used
to ``force'' the orientation on a document to
override the DSC comments. If an orientation is
being forced, then a ``tie fighter'' will appear
in front of the current orientation.
- Portrait
- Set the orientation to Portrait. This
implies no rotation. A portrait ori-
entation 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. Most of the Landscape docu-
ments that I have encountered require
a 90 clockwise rotation of the paper
to view. However, there is no stan-
dard and some documents need to be
rotated the other way. The swap land-
scape button allows gvu to automati-
cally 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 ``dot'' appears in
front of the current media. The first mouse
button sets the default media. The DSC comments
may specify the page media that overrides the
default. In this case, a "document" appears in
front of the current media. The second mouse
button can be used to ``force'' the media on a
document to override the DSC comments. Forcing
the media on an EPSF figure will override the
Bounding Box. This makes is easy to view a fig-
ure with an incorrect %%BoundingBox comment. If
a media is being forced, then a ``tie fighter''
will appear 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.
Letter 612 x 792 (8.5 x 11 in.)

APPLICATION RESOURCES
The following application resources may be set to control
the default behavior of gvu.
- showTitle (class Labels)
- Tells whether to display the %%Title comment.
The default is ``true''.
- showDate (class Labels)
- Tells whether to display the %%Data comment.
The default is ``true''.
- showLocator (class Labels)
- Tells whether to display the locator. The
default is ``true''.
- autoCenter (class AutoCenter)
- Tells whether to center the page within the
viewport whenever the page size changes. The
default is ``true''.
- horizonalMargin (class Margin)
- Tells how many pixels gvu should reserve for
window decorations in the horizontal direction.
The default value is ``20''.
- verticalMargin (class Margin)
- Tells how many pixels gvu should reserve for
window decorations in the vertical direction.
The default value is ``44''.
- minimumMagstep (class Magstep)
- Tells the smallest magstep to display. The
default is ``-5''.
- maximumMagstep (class Magstep)
- Tells the largest magstep to display. The
default is ``5''.
- magstep (class Magstep)
- Sets the default magstep. The default is ``0''.
- orientation (class Orientation)
- Sets the default orientation. The default is
``Portrait''.
- page (class Page)
- Gives the initial page to display. This
resource only affects the display of the file
listed on the command line. The default is
NULL.
- pageMedia (class PageMedia)
- Sets the default page media. The default is
``Letter''.
- forceOrientation (class Force)
- Tells whether to force the orientation on the
document. The default is ``false''.
- forcePageMedia (class Force)
- Tells whether to force the page media on the
document. The default is ``false''.
- swapLandscape (class SwapLandscape)
- Tells whether to swap the meaning of Landscape
and Seascape. The default is ``false''.
- printCommand (class PrintCommand)
- Sets the command used for printing. The printer
environment variable is set to the desired
printer and then this command is executed using
popen. This command should read from ``stdin''
and send the file to the appropriate printer.
The default value is ``lpr'' for BSD and ``lp''
for System V.
- printerVariable (class PrinterVariable)
- Gives the name of the printer environment vari-
able. The default value is ``PRINTER'' for BSD
and ``LPDEST'' for System V.
- defaultPrinter (class DefaultPrinter)
- Gives the printer name to use when the printer
environment variable is not set. The default
value is NULL.
- printPrompt (class PrintPrompt)
- Sets the prompt used to ask for the printer
name. The default value is ``Printer Name: ''.
- printFail (class printFail)
- Sets the string used to inform the user that the
printer command failed. The default is
``"lpr" command failed.''.
- openPrompt (class OpenPrompt)
- Sets the prompt used to ask for a file name to
open. The default value is ``Open File: ''.
- openFail (class OpenFail)
- Sets the string used to inform the user that the
open failed. The default value is
``Cannot open file: ''.
- savePrompt (class SavePrompt)
- Sets the prompt used to ask for a file name to
save. The default value is ``Save File: ''.
- saveFail (class SaveFail)
- Sets the string used to inform the user that the
save failed. The default value is
``Cannot save file: ''.
- openWindows (class OpenWindows)
- OpenWindows servers sometimes cause error mes-
sages about bitmaps not being 1 bit deep. Turn-
ing on this resource avoids the problem by not
using any bitmaps. You lose the functionality
of having the current magstep, orientation and
media marked on the popup menus. The default
value is ``false''.
- ncdwm (class Ncdwm)
- The Xt Intrinsics has a bug that causes bogus
information in the window manager size hints.
Ncdwm and possibly other window managers get
confused by the bogus information and make the
window extremely small. Twm and mwm ignore the
bogus information. Turning on the resource
avoids the problem with ncdwm by doing things
slightly differently. However, this can confuse
other window managers such as mwm. This bug is
fixed in X11R5 fix-10. You should only set this
resource if you have the problem. The default
value is ``false''.
GHOSTVIEW WIDGET RESOURCES
Certain resources in the Gvu widget may be set by the
user. These selected resources are presented below.
- arguments
- (class Arguments)
Additional arguments passed to the interpreter.
It is convenient to name files that preload
fonts here for PostScript programs that continu-
ally reload fonts while rendering a page. The
default is no additional arguments.
- busyCursor (class Cursor)
- The cursor shown when ghostscript is rendering
to the window. The busy cursor is set to the
``target'' by the application defaults.
- cursor (class Cursor)
- The cursor shown when ghostscript is idle. The
default cursor is the ``crosshair''.
- interpreter (class Interpreter)
- The name of the executable to call to render the
PostScript. It is convenient to set this
resource to the path of an alternate version of
ghostscript for testing. The default value is
``gs''.
- palette (class Palette)
- Tells ghostscript how to restrict the palette
used when rendering. The possible values are
``color'', ``grayscale'', and ``monochrome''.
The default value is ``color''.
- quiet (class Quiet)
- Tells ghostscript whether to supress informa-
tional messages. The default value is ``true''.
- safer (class Safer)
- Tells ghostscript whether to run in ``safer''
mode. The default value is ``true''.
- useBackingPixmap (class UseBackingPixmap)
- Tells whether to use a backing pixmap. If this
resource is false, backing store is requested on
the Gvu 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.
GHOSTVIEW WIDGET ACTIONS
- notify(width height xdpi ydpi)
- The notify event is used by the gvu application
for the locator and popup zoom windows. If the
width and height are 0, the event is user 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 xdpi will default to the xdpi
if the ydpi is omitted.

ENVIRONMENT
LPDEST The LPDEST environment variable gives the
default printer destination on System V.
PRINTER The PRINTER environment variable gives the
default printer destination on BSD.
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 gvu 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.
BUGS
If you find a bug, please send a bug report to
ulric@siag.nu.
