If you really need Qt4 17 | support, please get in touch. 18 | 19 | 20 | v1.15.1 - 2016-09-13 21 | -------------------- 22 | 23 | Bugfix: 24 | 25 | * No longer advances two slides on mouse wheel when 26 | used with recent Qt5. Thanks to @nbecker for reporting 27 | this on GitHub. 28 | 29 | 30 | v1.15 - 2016-04-05 31 | ------------------ 32 | 33 | Changes in behaviour: 34 | 35 | * When compiling dspdfviewer yourself: 36 | * You must now execute the testsuite within a running X Server 37 | (Linux) or within a graphical environment (Windows/OSX). 38 | It will no longer try to set up one on its own. 39 | * The testsuite expects two screens to be connected by default. 40 | If your environment only has one screen, you can pass 41 | -DRunDualScreenTests=OFF at CMake time to avoid a test failure. 42 | * Instead of offering pre-rendered PDFs for download, they are now 43 | included in the source tree. The option `DownloadTestPDF` has 44 | been replaced with `UsePrerenderedPDF` accordingly. 45 | * Qt5 is now the default. If you want to build against Qt4, 46 | you will have to pass -DUseQtFive=OFF to CMake. 47 | Note that Qt4 support is now considered deprecated and will be 48 | removed in one of the next versions. Please file a bug if your 49 | system does not work correctly with Qt5. 50 | 51 | New features: 52 | 53 | * Predictable memory usage and configurable cache size limit 54 | * Previously, dspdfviewer allowed to cache 100 images. It did not 55 | matter whether these where thumbnails or full pages, resulting in 56 | unpredictable memory usage. 57 | * Now you can specify memory limit for the cache in MiB, using 58 | the command-line parameter --cache-size. The default value 1024 59 | is normally fine, setting is below 250 will result in severe 60 | performance crippling. 61 | * This only affects the *cache* memory. The total memory usage of 62 | dspdfviewer can be up to 300M higher, mainly depending on whether 63 | the shared libraries (poppler/qt) are also used by other programs, 64 | or are specifically loaded for dspdfviewer. 65 | 66 | Other: 67 | 68 | * A lot of work has gone into the Windows port, and compiling on 69 | Windows with MSVC is now part of the automated testing. 70 | * The testsuite is currently disabled on big-endian machines. 71 | It keeps failing with what appears to be an endian issue. 72 | If you want to help out, you can force the testsuite to run 73 | by passing -DRunTestsOnBigEndian=ON at cmake time. 74 | 75 | 76 | v1.14 - 2015-12-01 77 | ------------------ 78 | 79 | New features: 80 | 81 | * Translation support 82 | * For now, a german translation is included, thanks to projekter. 83 | * Experimental i3 support 84 | * If you specify the --i3-workaround=true option, dspdfviewer will try to 85 | use i3-cmd to move the audience window one screen to the right. 86 | * This code is not well tested, please leave feedback and suggestions. 87 | * Add support for Qt5 88 | * Add support for Windows, thanks to projekter. 89 | 90 | 91 | v1.13.1 - 2015-08-06 92 | -------------------- 93 | 94 | This is a bugfix and maintenance release for v1.13. 95 | 96 | Bugfixes: 97 | 98 | * Regression: Changing slide while blanked crashed the program 99 | 100 | Other: 101 | 102 | * A `dspdfviewer.desktop` file has been added, helping desktop enviroments 103 | to include the program in their menus 104 | * `dspdfviewer --help` informs about the manpage and the F1 help box 105 | * This changelog has been started, listing changes since v1.8. 106 | 107 | 108 | 109 | v1.13 - 2015-07-30 110 | ------------------ 111 | 112 | New features: 113 | 114 | * dspdfviewer will open a file chooser dialog when started without a 115 | command-line file parameter (instead of aborting with error message) 116 | * Hyperlinks between pages are now clickable 117 | * The height of the bottom pane (thumbnails and clocks) on the second 118 | screen can now be configured 119 | 120 | 121 | 122 | v1.12 - 2015-07-23 123 | ------------------ 124 | 125 | New features: 126 | 127 | * Added support for the Logitech R400 presenter remote control. 128 | * Secondary screen can be toggled between notes and main presentation. 129 | * `F1` or `?` key show a quick help box. 130 | * A configuration file at `~/.config/dspdfviewer.ini` can now be 131 | used in addition to command-line parameters. 132 | 133 | 134 | 135 | v1.11 - 2014-07-12 136 | ------------------ 137 | 138 | New features: 139 | 140 | * The window for the presenter now spawns on the primary screen 141 | (see `man xrandr` on how to define this) which is assumed to be 142 | the notebook you carry to the presenation site. 143 | * The windows now have different window titles and window roles. 144 | This enables scripting, especially useful on tiling window managers. 145 | * dspdfviewer will now watch the file on disk and re-read when it changes. 146 | This is useful if you're using dspdfviewer as a previewer while 147 | writing a presentation. 148 | 149 | 150 | 151 | v1.10.1 - 2013-10-22 152 | -------------------- 153 | 154 | This is a bugfix and maintenance release for 1.10. 155 | 156 | Bugfixes: 157 | 158 | * Regression: Primary and secondary window could not be swapped on Kubuntu 13.10. 159 | 160 | 161 | 162 | 1.10 - 2013-03-25 163 | ----------------- 164 | 165 | Improvement: 166 | 167 | * Speed up initial rendering 168 | 169 | 170 | 171 | 1.9 - 2013-01-23 172 | ---------------- 173 | 174 | New feature: 175 | 176 | * The "go to" command (`G`) now displays the range of valid page numbers 177 | 178 | 179 | 180 | 1.8 - 2012-12-11 181 | ---------------- 182 | 183 | Initial *free and open source software* release: 184 | 185 | * dspdfviewer is now distributed under the GNU GPL, version 2, or 186 | (at your option) any later version. 187 | -------------------------------------------------------------------------------- /CMakeLists.txt: -------------------------------------------------------------------------------- 1 | # /* 2 | # dspdfviewer - Dual Screen PDF Viewer for LaTeX-Beamer 3 | # Copyright (C) 2012 Danny Edel 4 | # 5 | # This program is free software; you can redistribute it and/or modify 6 | # it under the terms of the GNU General Public License as published by 7 | # the Free Software Foundation; either version 2 of the License, or 8 | # (at your option) any later version. 9 | # 10 | # This program is distributed in the hope that it will be useful, 11 | # but WITHOUT ANY WARRANTY; without even the implied warranty of 12 | # MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

Most important ones are probably: 13 | 14 | Command line: 15 | 16 | dspdfviewer [options] *pdf-file* 17 | 18 | where the most useful option is probably -f, because it enables you to use the software with a standard pdf (i.e. not specifically built for latex-beamer). 19 | 20 | In-Program-Controls: 21 | 22 | Left/Right, Mouse Buttons or Mouse Wheel: Back/Forward 23 | 24 | S or F12: Swap screens (if you see the wall clock on the projector) 25 | 26 | B or .

Controls

11 | 12 |

You can use the following controls while dspdfviewer is running.

13 | 14 |

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. 15 | 16 | 17 | 18 | 19 | 20 | 21 | 22 | 23 | 24 | 25 | 26 | 27 | 29 | 30 | 31 | 32 | 34 | 35 | 36 | 37 | 38 | 39 | 40 | 41 | 43 | 44 | 45 | 46 | 47 |

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.

48 |

Note that the Home key may be called "Pos 1" on some keyboards.

Description

11 | 12 |

dspdfviewer is intended for presentations created with the latex-beamer class, specifically documents created with the show notes on second screen=right option.

13 | 14 |

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 "private" 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.

15 | 16 |

On the secondary screen you will see three clocks: A "wall clock", a "presentation" clock and a "slide" clock.

17 | 18 |

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) displays the time you spent on the current slide.

19 | 20 |

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.

21 | 22 |

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.

23 | 24 |

If you want to reset the clocks to zero, press the "Home" button on the keybord.

dspdfviewer − Dual-Screen PDF Viewer

11 | 12 | 13 | -------------------------------------------------------------------------------- /docs/Windows/options.html: -------------------------------------------------------------------------------- 1 | 3 | 4 | 5 | 6 | Options 7 | 8 | 9 | 10 |

Options

11 | 12 |

The exact behaviour of dspdfviewer is configurable using command-line parameters.

13 | 14 |

Unless otherwise noted, all command-line options can be written in a configuration file. See the Files section for the location.

15 | 16 |

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.

17 | 18 |

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.

19 | 20 |

For example, bottom-pane-height=20 is a valid configuration line.

21 | 22 |

If an option is specified in both the configuration file and the command-line, the command-line value takes precedence.

23 | 24 |

Note for options of type <bool>: They take true, false, 0 or 1 as arguments. For example, --use-second-screen false can be expressed as --use-second-screen 0 or shortened to -u0. 25 | 26 | 27 | 28 | 29 | 30 | 31 | 32 | 33 | 34 | 35 | 36 | 38 | 39 | 40 | 41 | 45 | 46 | 47 | 48 | 51 | 52 | 53 | 54 | 56 | 57 | 58 | 59 | 61 | 62 | 63 | 64 | 66 | 67 | 68 | 70 | 71 | 72 | 73 | 74 | 75 | 76 | 77 | 78 | 79 | 80 | 81 | 82 | 83 | 84 | 85 | 86 | 87 | 88 | 89 | 91 | 92 |
-h, --helpShow 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 options below.

-u, --use-second-screen <bool>

Controls whether the program actually works as a dual-screen viewer.

42 |

The default is true.

43 |

If you only have one screen, but still want to use the cache features, 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).

44 |

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.

49 |

The default is true.

50 |

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)

55 |

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)

60 |

Note: If you set this to zero, you will not get a thumbnail for the next page rendered before you have visited it.

-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.

65 |
-d, --duplicate <bool>

Duplicate (true, 1) or hide (false, 0) the audience’s screen next to the notes on the second screen.

69 |

The default is false.

-t, --thumbnails <bool>

Show (true, 1) or hide (false, 0) the thumbnails on the second screen.

-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 second 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.

90 |

Default value 20.

Presenter remote controls

11 | 12 |

Most (maybe not all) presenter remote controls technically act as a keyboard 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.

Note: Use "show notes on second screen=right" because dspdfviewer assumes that the right half of the page is the notes.

Its main purpose is to decouple installation instructions 8 | from the primary sourcecode tree. 9 | You can [inspect the sourcecode on github.][sourcecode] 10 | 11 | It is a work-in-progress, and accepting suggestions and help. 12 | Read further down on how to get involved. 13 | 14 | ## What is dspdfviewer? 15 | dspdfviewer is a pre-rendering and caching (read: *fast*) full-screen pdf 16 | viewer specifically designed for latex-beamer presentations, 17 | that were created with the `show notes on second screen=right` option. 18 | 19 | It will take your double-width PDF file, split it in half, render the 20 | left half to the audience (via a beamer) and the right half - which will 21 | contain the notes you entered in your LaTeX source - on your laptop screen. 22 | 23 | In addition, your laptop screen will contain some counters and a wall-clock, 24 | which may help you time your presentation right. 25 | 26 | Both screens will be rendered and scaled completely independent of each other, 27 | so you can use two screens with different resolutions and/or aspect ratios, 28 | such as your 16:10 laptop screen and a 4:3 beamer, or the other way around. 29 | Please use both devices' native resolutions for maximum image quality. 30 | 31 | ## How do I use it? 32 | 33 | First of all: You should have a pdf generated by `latex-beamer` with 34 | the `show notes on second screen=right` option. 35 | While you can leave the `=right` part out (is the default if not specified) 36 | dspdfviewer will not work correctly if you specify any other direction; 37 | It always assumes the left half is for the audience and the right half 38 | is for the presenter. 39 | 40 | Simply call `dspdfviewer /path/to/your/presentation.pdf` to start. 41 | If you start `dspdfviewer` without a command-line parameter, 42 | it will use a file-open-dialog-window to ask you for a PDF file. 43 | 44 | Once its loaded, try the following commands: 45 | 46 | * Swap Screens (If the audience sees the clock and the note page) 47 | * Keyboard: `S`, `F12` 48 | * Advance one frame 49 | * Mouse: `Left-Click`, `Wheel-Down` 50 | * Keyboard: `Right`, `Down` 51 | * Back one frame 52 | * Mouse: `Right-Click`, `Wheel-Up` 53 | * Keyboard: `Left`, `Up` 54 | * Keybindings popup 55 | * Keyboard: `F1` or `?` 56 | * Quit program 57 | * Keyboard: `Q` 58 | 59 | For a more complete list, please read the program's manual page. 60 | With dspdfviewer installed, a manual page corresponding to your installed version 61 | should be available as `man dspdfviewer`. 62 | 63 | In addition, you can [access the manpage online]. Note that the online version 64 | is generated from git and may contain commands not yet in your installation. 65 | You can also read the [release manpage] from version v1.14. 66 | 67 | [access the manpage online]: manpage.html 68 | [release manpage]: manpage-release.html 69 | 70 | If the manual doesn't answer your question, feel free to open a ticket in 71 | the [issues system] requesting help or clarification. 72 | 73 | ## How do I install it? 74 | 75 | This varies depending on your operating system. 76 | Please follow the specific instructions: 77 | 78 | * Linux and other Unixes 79 | * [Debian](installation/debian.html) 80 | * [Ubuntu](installation/ubuntu.html) 81 | * [Gentoo](installation/gentoo.html) 82 | * [Arch](installation/arch.html) 83 | * [Generic (from source)](installation/) 84 | * [Mac OS](installation/macos.html) 85 | * [Windows](installation/windows.html) 86 | 87 | If your system isn't listed here, please try the Generic instructions. 88 | Feel free to open a ticket in the [issues system] asking for help if something goes wrong. 89 | 90 | [issues system]: https://github.com/dannyedel/dspdfviewer/issues 91 | 92 | ## How do I contribute? 93 | 94 | First, you help a lot if you use the software and report any problems or 95 | missing features in the [issues system]. 96 | 97 | If you want to help on development, please use github's 98 | amazing [pull request] feature. 99 | 100 | The full [sourcecode], which includes [this website], is available 101 | to view and improve, 102 | and any help is greatly appreciated! 103 | 104 | [sourcecode]: https://github.com/dannyedel/dspdfviewer 105 | [this website]: https://github.com/dannyedel/dspdfviewer/tree/master/docs/ 106 | [pull request]: https://help.github.com/articles/using-pull-requests/ 107 | 108 | ## Who built this program? 109 | 110 | Github maintains a [contributors] list for the sourcecode. 111 | 112 | [contributors]: https://github.com/dannyedel/dspdfviewer/graphs/contributors 113 | 114 | ## Contact information 115 | 116 | If you have any questions that don't fit the [issues system], 117 | you can contact me ([@dannyedel]) by e-mail at `mail@danny-edel.de`. 118 | 119 | Since e-mails on the internet are everything but secure, 120 | please use my [gpg key] to send encrypted. 121 | 122 | [@dannyedel]: https://github.com/dannyedel 123 | [gpg key]: https://sks-keyservers.net/pks/lookup?op=get&search=0xF132F84C7183343C 124 | -------------------------------------------------------------------------------- /docs/installation/arch.md: -------------------------------------------------------------------------------- 1 | --- 2 | title: Installation on Arch Linux 3 | layout: default 4 | --- 5 | 6 | `dspdfviewer` is available via the [Arch User Repository AUR][aur]. 7 | 8 | There is a PKGBUILD file for the [latest release version][release]. 9 | 10 | [aur]: https://wiki.archlinux.org/index.php/Arch_User_Repository 11 | [release]: https://aur.archlinux.org/packages/dspdfviewer/ 12 | [git]: https://aur.archlinux.org/packages/dspdfviewer-git/ 13 | -------------------------------------------------------------------------------- /docs/installation/daily-deb.md: -------------------------------------------------------------------------------- 1 | --- 2 | title: Installation of daily debs, directly from git 3 | --- 4 | 5 | The daily deb repository has been discontinued. 6 | 7 | Please use the official [Debian instructions][deb] and/or [compile from source yourself][src]. 8 | 9 | [deb]: /installation/debian 10 | [src]: /installation/source 11 | -------------------------------------------------------------------------------- /docs/installation/debian.md: -------------------------------------------------------------------------------- 1 | --- 2 | title: Installation on Debian 3 | layout: default 4 | --- 5 | 6 | If you're running Debian, it is recommended to use the version included in your 7 | distribution.

(make a build sub-directory) 19 | `mkdir build ; cd build` 20 | 4. (create Makefile) 21 | `cmake ..` 22 | (*note: this step should tell you about missing build-deps*) 23 | 5. (build) 24 | `make` 25 | 6. (install) 26 | `make install` 27 | (optional) 28 | 29 | Be advised that there is *no* automatic uninstallation, 30 | so please consider packaging 31 | the software using your distribution's preferred packaging method. 32 | 33 | The `cmake` step accepts `--prefix=` and the generated 34 | `make install` accepts the `DESTDIR` setting, so your packager can 35 | redirect the files where it needs them. 36 | 37 | ## Updating 38 | 39 | 1. (enter directory) 40 | `cd .../dspdfviewer/build/` 41 | 2. (update from git) 42 | `git pull` 43 | 3. (build) 44 | `make` 45 | 4.

These tests will require PDFs to function, which 46 | are included in the tarball, but can be (re)generated during the build. 47 | * `RunDualScreenTests` boolean, default ON 48 | * Include unit tests that require two screens to be connected. 49 | * `RunTestsOnBigEndian` boolean, default OFF 50 | * Run the unit tests on a big-endian system. By default, tests are 51 | only run on little-endian systems. 52 | * `UsePrerenderedPDF` boolean, default OFF 53 | * Use pre-rendered PDFs for the test suite, instead of compiling them 54 | on-the-fly during the build. 55 | * Enable this to speed up build time and reduce dependencies. 56 | * The default value will probably switch to ON in a future version. 57 | * `BoostStaticLink` boolean, default OFF 58 | * Link against the `boost` libraries statically (ON) or dynamically (OFF) 59 | * If your platform supports dynamic linking, ideally through a package manager 60 | that takes care of installing and updating the libraries, it is highly 61 | recommended to stick to dynamic linking. 62 | * If you link statically, please ensure that you recompile when the boost 63 | libraries get updated. 64 | * `WindowsStaticLink` boolean, default ON 65 | * Only relevant for Windows builds using the MS Visual C++ Compiler. 66 | * Sets the `/MT` instead of the `/MD` compiler flags. 67 | * `CodeCoverage` boolean, default OFF 68 | * This flag adds the necessary flags to record code coverage (currently 69 | only supported with gcc). Only of interest for developers, this massively 70 | slows down the code. Don't use it for production builds. 71 | 72 | 73 | --- 74 | 75 | ## Historical options (no longer present in current version) 76 | 77 | * `DownloadTestPDF` 78 | * This option is ignored since v1.15, 79 | because the pre-rendered PDF files are now distributed in 80 | the release tarball. 81 | 82 | back to [compile from source](/installation/) 83 | -------------------------------------------------------------------------------- /docs/installation/source/stable.md: -------------------------------------------------------------------------------- 1 | --- 2 | title: Compile the stable release from source 3 | --- 4 | 5 | 6 | Note: Please take a look at the [github releases][rel] page to get an 7 | overview of the released versions and how they changed. 8 | 9 | You can also jump directly to the [latest version][latest]. 10 | 11 | [rel]: https://github.com/dannyedel/dspdfviewer/releases 12 | [latest]: https://github.com/dannyedel/dspdfviewer/releases/latest 13 | 14 | Dependencies: You will need to install the [build dependencies][bdep] 15 | before you can compile this software. 16 | 17 | 18 | Info: When compiling software yourself, you have the opportunity to 19 | change certain aspects. 20 | Please read the [compile-time options list][opts] if you want to 21 | fine-tune certain things. 22 | 23 | [opts]: /installation/source/options.html 24 | [bdep]: /installation/source/dependencies.html 25 | 26 | {% highlight bash %} 27 | VERSION=1.33.7 # Change this! 28 | wget https://github.com/dannyedel/dspdfviewer/archive/v$VERSION.tar.gz 29 | wget https://github.com/dannyedel/dspdfviewer/releases/download/v$VERSION/dspdfviewer-$VERSION.tar.gz.asc 30 | gpgv dspdfviewer-$VERSION.tar.gz.asc v$VERSION.tar.gz # verify archive integrity 31 | cd dspdfviewer-$VERSION 32 | mkdir build 33 | cd build 34 | cmake .. # You could pass options here (see above) 35 | make 36 | 37 | # 38 | # You can now use the software as ./dspdfviewer 39 | # 40 | 41 | make install # optional, requires root privileges 42 | {% endhighlight %} 43 | 44 | Note that there is no uninstall script, so please consider replacing the final 45 | `make install` with something more appropriate for your distribution. 46 | It will respect the usual DESTDIR parameter. 47 | 48 | If you are willing to write and maintain a dspdfviewer installation 49 | script/package for a specific distribution, please get in touch. 50 | -------------------------------------------------------------------------------- /docs/installation/ubuntu.md: -------------------------------------------------------------------------------- 1 | --- 2 | title: Installation on Ubuntu 3 | layout: default 4 | --- 5 | 6 | `dspdfviewer` is **included in the main repositories** since wily (2015/10). 7 | 8 | Simply call `apt-get install dspdfviewer` or 9 | use your favorite GUI to install the `dspdfviewer` package. 10 | 11 | ##

Advanced users: Compile dspdfviewer from source 23 | 24 | In the course of adding a Windows build to the CI tests, 25 | [@projekter][] created [archives of poppler and its dependencies][deps], 26 | compiled with MSVC 2013. 27 | This can of course also be used to quickly get a development environment set up 28 | on a windows machine, without needing to spend much time on compiling 29 | dependencies. 30 | 31 | *Warning: The dependency archive is provided as-is; 32 | do not expect to receive any kind of update support. 33 | Please only use it as a quickstart mechanism, 34 | and don't expect the included DLLs to be continually 35 | updated with patches from upstream. 36 | If you plan to distribute a dspdfviewer binary, 37 | do yourself a favor and re-compile the 38 | most recent stable versions of all dependencies.* 39 | 40 | In addition to the dependency archive, 41 | you will also need the following programs and libraries on your system: 42 | 43 | * MSVC 2013 (also known as version 12.0) 44 | * Qt 5.x (make sure you pick the version for MSVC 2013 32bit) 45 | * Boost (also make sure you pick the version for MSVC 12.0 32 bit) 46 | * CMake 47 | * git 48 | * Something to extract the archive with (7z for example) 49 | 50 | To use the prebuilt DLLs, extract the archives directly to `c:\` and 51 | make sure to set `-DWindowsStaticLink=OFF` at cmake time, 52 | and it is probably easier to use `-DBoostStaticLink=ON` on a Windows build. 53 | You will also need to set the `PATH` environment to contain the directories of the 54 | DLLs unless you want to copy them to the build dir. 55 | 56 | On a debug build, you must make sure that the debug version of `poppler-qt5.dll` is loaded, 57 | for example by copying it into the executable's directory. 58 | See [buildme.bat][] or the [AppVeyor CI configuration][appveyor] 59 | for examples of how to set up and compile a Debug configuration. 60 | 61 | [@projekter]: https://github.com/projekter 62 | [@projekters release page]: https://github.com/projekter/dspdfviewer/releases 63 | [deps]: https://github.com/projekter/dspdfviewer/releases/tag/v1.14-42-g4acfb31 64 | [buildme.bat]: https://gist.github.com/dannyedel/549e57aa73936d7d7a7f 65 | [appveyor]: https://github.com/dannyedel/dspdfviewer/blob/master/.appveyor.yml 66 | [latest]: https://github.com/projekter/dspdfviewer/releases/latest 67 | -------------------------------------------------------------------------------- /docs/robots.txt: -------------------------------------------------------------------------------- 1 | User-Agent: * 2 | Disallow: 3 | -------------------------------------------------------------------------------- /dspdfviewer.desktop: -------------------------------------------------------------------------------- 1 | [Desktop Entry] 2 | Type=Application 3 | Version=1.0 4 | Name=DS PDF Viewer 5 | Comment=Dual-Screen PDF Viewer for LaTeX-Beamer presentations utilizing the "show notes on second screen" option 6 | Keywords=pdf;presentation;latex;beamer;notes; 7 | Exec=dspdfviewer %f 8 | -------------------------------------------------------------------------------- /dspdfviewer.h: -------------------------------------------------------------------------------- 1 | /* 2 | dspdfviewer - Dual Screen PDF Viewer for LaTeX-Beamer 3 | Copyright (C) 2012 Danny Edel 4 | 5 | This program is free software; you can redistribute it and/or modify 6 | it under the terms of the GNU General Public License as published by 7 | the Free Software Foundation; either version 2 of the License, or 8 | (at your option) any later version. 9 | 10 | This program is distributed in the hope that it will be useful, 11 | but WITHOUT ANY WARRANTY; without even the implied warranty of 12 | MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
