DSPDFVIEWER(1) General Commands Manual DSPDFVIEWER(1) NAME dspdfviewer - Dual-Screen PDF Viewer SYNOPSIS dspdfviewer [options] [filename] DESCRIPTION dspdfviewer is intended for presentations created with the latex-beamer class, specifically documents created with the show notes on second screen=right option. Its purpose is to display the left half of a page on the audience's screen (which will most commonly be a projector) and the right half on your "pri- vate" screen (think: the notebook you carried to the presentation site). The basic idea is that you will display personal notes and information to help you with your presentation on your personal screen, while the audience sees only the PDF they are supposed to see. On the secondary screen you will see three clocks: A "wall clock", a "pre- sentation" clock and a "slide" clock. The wall clock in the bottom left corner that display current time of day, the presentation clock (labeled "Total") counts the time you spent since you started the presentation, and the "slide" counter (bottom right) dis- plays the time you spent on the current slide. The clocks don't start the second you launch the program, the idea behind that behaviour is that many people have a "title" slide active long before the audience even arrives. Once you use the next/previous slide commands, the clock starts. If you want to start the clock, but still display the title slide, just press "previous" (for example, Up Arrow or Right Mouse Button) on the title slide. If you want to reset the clocks to zero, press the "Home" button on the keybord. OPTIONS The exact behaviour of dspdfviewer is configurable using command-line para- meters. Unless otherwise noted, all command-line options can be written in a con- figuration file. See the FILES section for the location. For the command-line parameters, this program follows the usual GNU command line syntax, with long options starting with two dashes ('-'). A summary of options is included below. If you specify those in a configuration file, write one option per line, use the long version without the two leading dashes, followed by an equals sign and the desired value. For example, bottom-pane-height=20 is a valid configuration line. If an option is specified in both the configuration file and the command- line, the command-line value takes precedence. Note for options of type <bool>: They take true, false, 0 or 1 as argu- ments. For example, --use-second-screen false can be expressed as --use- second-screen 0 or shortened to -u0. -h, --help Show summary of options. -f, --full-page Use the presentation program with a normal single-screen PDF, that is display the full page on both the primary and secondary monitor. The secondary screen still contains timers and thumbnails to help you with your presentation, unless you disable them using the op- tions below. -u, --use-second-screen <bool> Controls whether the program actually works as a dual-screen viewer. The default is true. If you only have one screen, but still want to use the cache fea- tures, you can set this option to false. If the window ends up on the wrong display, you can still use the switch command (see below). What comes out on the primary screen depends on whether you use the -f Option: -u0 -f results in a simple full-screen PDF viewer, while -u0 without -f still splits the page in half and outputs only the left frame. -l, --hyperlink-support <bool> Controls whether the program makes PDF Hyperlinks clickable. The default is true. While it is normally desired to have clickable hyperlinks, if you cannot control the position of your pointer (if your remote control has only left-click and right-click) it might be safer to disable hyperlinks. --prerender-previous-pages n When jumping to slide m, also pre-render the slides (m-n)..(m-1) (default 3) Note: If you set this to zero, you will not get a thumbnail for the previous page rendered before you have visited it. --prerender-next-pages n When jumping to slide m, also pre-render the slides (m+1)..(m+n) (default 10) Note: If you set this to zero, you will not get a thumbnail for the next page rendered before you have visited it. --cache-size n (in megabytes / MiB) This controls how much memory dspdfviewer is allowed to use for caching rendered pages. The default value is 1024, meaning 1 GiB of RAM. Note that the memory used for active rendering processes, as well as the currently displayed images are not included in the ac- counting, so the total memory usage of dspdfviewer will be higher than this. CAVEAT: It is currently not verified that this memory is enough to hold all prerendered pages. If you make the cache too small to hold the prerendered pages, it will start dropping the first rendered (adjacent to the current page), resulting in very poor performance. If in doubt, set a larger cache or a lower prerender amount. -a, --presenter-area <bool> Show (true, 1) or hide (false, 0) the presenter's area on the second screen. If this is set to zero, the following options will have no effect. -d, --duplicate <bool> Duplicate (true, 1) or hide (false, 0) the audience's screen next to the notes on the second screen. The default is false. -t, --thumbnails <bool> Show (true, 1) or hide (false, 0) the thumbnails on the second screen. -T, --thumbnail-page-part <pagepart> Show this part of the page for thumbnails, valid values are "left", "right" or "both". -w, --wall-clock <bool> Show (true, 1) or hide (false, 0) the wall clock on the second screen. -p, --presentation-clock <bool> Show (true, 1) or hide (false, 0) the presentation clock on the sec- ond screen. -s, --slide-clock <bool> Show (true, 1) or hide (false, 0) the slide clock on the second screen. -b, --bottom-pane-height n Configure how large the presenter area on the second screen will be, unit is percent of second screen's total height. Default value 20. --i3-workaround <bool> This tries to ask the i3 window manager (by calling the i3-msg com- mand) to move the audience window to "the other screen". This is considered an experimental feature and disabled by default. Read the runtimeconfiguration.cpp source code for more info. CONTROLS You can use the following controls while dspdfviewer is running. Note that mouse-clicks are subject to pointer position if the hyperlink support is enabled. If your mouse cursor changes to a hand, it will follow the link you are hovering on a click. Keyboard: ?, F1 Display quick-help (most important key bindings) Keyboard: Spacebar, Page Down / Mouse: Left-Click, Wheel Down Go one page forward Additional keyboard aliases: Down, Right, Return, Enter, N, F Keyboard: Backspace, Page Up / Mouse: Right-Click, Wheel Up Go one page backward Additional keyboard aliases: Up, Left, P Keyboard: B, . (period) Toggle blanking of the audience screen Keyboard: G Go to specific page (a number entry window will pop up) Note that the this counts PDF pages, so a single slide having 6 un- masking steps will be 7 PDF pages long, including the initial near- blank page. Keyboard: Home, H Go to the first page and reset the clocks to zero. Use this if you want the clocks to stop at zero, use the G (goto) function to page 1 if you want to them to keep running. Note that the Home key may be called "Pos 1" on some keyboards. Keyboard: Escape, Q Quit dspdfviewer. Keyboard: S, F12 Switch primary and secondary screens Use this if the audience sees your 'note' side with the clocks and you see the actual presentation on your screen. If you just want to see the main presentation (for example, because the projector is behind you), use T. Keyboard: T Switch secondary screen's function Use this if you want to see the audience side on your screen, with- out showing the notes to the audience. Pressing the button again will switch back to normal operation. Keyboard: D Switch duplication of the audience's screen Use this if you want to see the audience side and the notes on your screen (so the full presentation), leaving the audience's screen un- touched. Pressing the button again will switch back to split mode. FILES ~/.config/dspdfviewer.ini You can specify all long command-line options (without leading --) here, in a "option=value" format, one per line. PRESENTER REMOTE CONTROLS Most (maybe not all) presenter remote controls technically act as a key- board sending one of the keystrokes listed either in the main or additional keybindings. If your remote control does not work as intended, please file a bug report describing what keystrokes it generates when you press its buttons. If there is no conflict, a keybinding will be included in the next release. BUGS None currently known. If you find any bugs, the preferred way to report them is at the github is- sue tracker at https://github.com/dannyedel/dspdfviewer/issues. As a fallback, you can send e-mail to mail@danny-edel.de with the word "dspdfviewer" in the subject line. SEE ALSO /usr/share/doc/latex-beamer/beameruserguide.pdf.gz from the latex-beamer package on how to create beamer presentations. Note: Use "show notes on second screen=right" because dspdfviewer assumes that the right half of the page is the notes. http://dspdfviewer.danny-edel.de for installation instructions and new release announcements.
