     mgp — MagicPoint -- an X11 based presentation tool


     mgp [-dhlnoqvBCGORSV] [-b bgcolor] [-c vfcap] [-f vfont] [-g geometry] [-p page]
         [-t timeslot] [-w wdir] [-x engine] [-D htmldir] [-E htmlimage] [-F mode,effect,value]
         [-Q quality] [-T timestampfile] [-X gsdevice] file


     mgp is an X11 based presentation tool.  It is designed to make simple presentations easy
     while to make complicated presentations possible.  Its presentation file (whose suffix is
     typically .mgp) is just text so that you can create presentation files quickly with your
     favorite editor (such as Emacs).

     The .mgp file consists of text and control commands (such as pagebreak, centering, and/or
     inline image).  Control commands are specified on the beginning of lines started with one %
     sign.  You can include numerous kinds of image format files onto the presentation file.

     mgp uses Japanese/English fonts in various sizes.  mgp uses X11 scalable fonts provided by
     X11 servers.  mgp can also utilize the Japanese outline font library, "VFlib", if configured
     to do so at compilation time.

     The following options are available:

     -b bgcolor
             Set background color to bgcolor.  (The default value is black)

     -c vfcap
             Specify a VFlib configuration file.

     -d [interval]
             Demonstration mode.  Browse all page automatically, spending interval secounds on
             each page and terminate. If interval is not specified, it will be set to 0.

     -f vfont
             Specify the font name to be used by VFlib.  (The default value is minsl)

     -g geometry
             Set the size and location of the window.  Please note that -g implies -o. mgp will
             not override the window manager if you specify the geometry.

     -h      Display the usage and exit without performing a presentation.

     -l      There are two kind of fonts available by VFlib; They are outline font and bitmap
             font.  By specifying -l, you can disable the use of outline fonts.

     -n      mgp accepts any key inputs from invoked terminal as KEY OPERATION described below.
             -n disables this feature.  (This option may be removed in the future release)

     -o      Do not override window manager.  (By default, mgp overrides window manager and
             occupies the whole display)

     -p page
             Start presentation from page, rather than the first page.

     -q      Do not beep on errors.

     -t timeslot
             Specify the timeslot assigned to the presentation in minute.  The timer is invoked
             when the second page is displayed and the remaining presentation time is indicated
             by the length of bar shown at the bottom of the display.  The timebar is updated
             when some X11 event is raised, for instance some keypress.  Timebar will be green if
             you have more than 50% of the timeslot, yellow while you have more than 30% of the
             timeslot, and red for the other cases.  When the assigned timeslot is expired,
             exceeding time is also shown as a timebar growing from left to right.  Current page
             is indicated by the position of a small vertical bar; the vertical bar is drawn at
             the leftend when the first page is displayed while the bar is drawn at the rightend
             when the last page is displayed.

     --title name
             Set the title of the window to name.

     -v      Display the MagicPoint version and exit without performing a presentation.

     -w wdir
             specifies the working directory used for store embedded images if any.  To generate
             an embedded MGP file, use mgpembed(1).

     -x engine
             Do not use rendering engine, specified by engine.  engine can be VFlib or FreeType.

     -B      Omit background image.

     -C      Use private colormap.

     -D htmldir
             Generate html pages of the presentation into htmldir.  You will need xwintoppm(1)
             (included in mgp kit), and pnmscale(1), cjpeg(1), and djpeg(1) (included in netpbm
             and Independent Jpeg Group jpeg package).

     -E htmlimage
             Specifies html image type. Now "jpg" and "png" are supported.  default value is
             "jpg". It works when -D option is set.

     -F mode,effect,value
             Specifies forward page cache options.  Mode, effect and value are numbers.  Mode
             specifies caching mode.  Mode 0 means caching is executed after 2 seconds idle.
             Mode 1 means caching is executed immediately.  Effect specifies 'special effect' for
             the forward page cache. Currently, two special effects are supported.  Effect 1
             means that the next page will come in from the left side.  Effect 2 means that the
             current page will go out to the left side.  Effect 0 means no special effect.  Value
             specifies speed of special effect.  Value 1 means the highest speed. A higher value
             for value decreases effect speed.

     -G      Specifies to turn on page guide function.  At the bottom of the screen, the titles
             of next page and previous page are displayed to assist the presentation.  Page guide
             can be turned on and off by keyboard too.

     -O      Obey to the window manager, but with less decoration around the window.  The
             behavior of this option is affected by how the window manager is implemented; this
             option may have no effect on some of the window managers.

     -Q quality
             Set background image quality(0-100).

     -R      mgp will usually reload the presentation file if it gets updated, based on the file
             modification time taken by stat(2).  -R disables this auto-reloading feature.

     -S      Be secure.  Skip directives that fork/exec the child process.  It is suggested to
             use this option if you got some presentation file from others.  This is enabled by

     -U      Be unsecure.  Enable directives that fork/exec the child process.  Allow to use non-
             ASCII filename.

     -T timestampfile
             If the option is specified, mgp will modify the content of timestampfile every time
             it updates the presentation window.  This option is useful for external process to
             understand when mgp modifies the window.

     -V      Be verbose.  Generate debugging output to standard output.

     -X gsdevice
             mgp sometimes invokes ghostscript(1) to render postscript images.  -X enables you to
             specify the device to be used by ghostscript(1).  If you specify gsdevice with a
             trailing '+', pnmscale(1) and pnmdepth(1) will be invoked for anti-aliasing.  The
             default gsdevice is "pnmraw+".


     The keyboard/mouse commands are:

     mouse button 1 (leftmost button)
             Go forward a page.  Space key, downward cursor key, scroll down key, "f" key, "j"
             key, and "n" key have the same effect.  If <number> is specified, go forward
             <number> pages.

     mouse button 3 (rightmost button)
             Go to the previous page.  "b" key, "k" key, "p" key, backspace key, scroll up key
             and upward cursor key have the same effect.  If <number> is specified, go back
             <number> pages.

     0 - 9 (number buttons)
             Set prefix number in decimal.  i.e. <number> = <number> * 10 + <keyN> - <key0>.  For
             example, by typing in "10g" you can jump to page 10.

     g       Go to the <number> page.  If number of 0 is specified, go to the last page.

     control key
             Display the page listing menu.  See below for details.

     G       Enable/disable page guide.  See description for option -G for details.

     x       Enable/disable rakugaki (jotting) mode.  You can make an annotation (by mouse) on
             the presentation.  Mouse button 2 (middle) has the same effect.

     X       Change the pen color for rakugaki (jotting) mode.

     t       Enable/disable the timebar if -t timeslot option is specified.

     c       Enable/disable forward page cache.

     w       Toggle full screen mode with EWMH.  (You need a EWMH-aware window manager and need
             to run mgp with -o or -g option)

             Repaint the current page.  Use this if you messed up the page by jotting too much.

             Reload the current presentation file.  If the current page becomes unavailable, page
             pointer will be moved back to 1.

     escape key
             Quit the currently running mgp.  "q" key also has the same effect.

     During the presentation, you can see the page list at the bottom of the window when you
     press a Control Key.  Choosing a page with the mouse and clicking it with the leftmost mouse
     button, you can go to corresponding page directly.  Releasing the Control Key, the page list
     disappears and you can continue with the current page.  This function is useful during the
     Q-and-A period after your presentation completes.


     mgp will look at a file named ~/.mgprc in your home directory. The path to this file can be
     overriden with the environment variable MGPRC.  The content of the file must be a limited
     set of magicpoint directives, one directive per line, without % sign.  Lines start with #,
     or empty lines, will be silently ignored.  See SYNTAX for eligible directives.

     mgp imports various image draw functions from xloadimage(1).  This means that the location
     of image files can be specified by ~/.xloadimagerc file.  If you specify the presentation
     file with its directory, that directory is searched first and then the path specified in the
     ~/.xloadimagerc is searched.


     MGPRC   Full path of the configuration file. When unset, ~/.mgprc is used.


     The presentation file can include directives to call the external process, just like shell
     process.  Therefore, the presentation file should be treated just like shell script or perl
     script.  This is STRONGLY recommended to review the content of the presentation file before
     invoking mgp, if you got the file from others.  By adding the -S option to the command line
     argument, directives that call external processes will be skipped.
