DS PDF Viewer (dspdfviewer) — a specialized C++ / QT graphical application for viewing PDF presentations in LaTeX–Bamer in the “two screen mode” (Dual-Screen PDF Viewer).
LaTeX most popular set of macrodactylini (the macro package) of the computer typesetting system TeX, which makes it easier to set complex documents. The package allows you to automate many of the tasks of typing and preparation of articles, besides the basic set, there are many expansion packs (thanks to the system’s capabilities is virtually unlimited).
Beamer — created in the 2008 year class for LaTeX allows you to create slides for presentations with the possibility of incorporating complex mathematical formulas, chemical equations, illustrations, and animations. Created presentation may have a distinct structure that is comfortable to navigate and move during the presentation. This class of LaTeX has special commands for the definition of “slide“, extended syntax for color management, the order of appearance of the elements of the slide and more…
The purpose of creating DS PDF Viewer is the ability to display the left page of a PDF document on the screen the audience (often the projector)and the right part on the screen of the lecturer (e.g. laptop). The basic idea is that personal notes and additional information (for presentations) displayed on the screen of the lecturer, and the audience sees only the page with the slides in the presentation.
In addition to slide on the second screen of the DS PDF Viewer can display thumbnail of previous and next pages, current time (digital clock with the system time), time of viewing the slide presentation and the total time from the beginning of the presentation. The clock on the screen does not start immediately, but start with the beginning of the scan if desired/necessary, they can be reset and/or disable.
DS PDF Viewer allows you to set options from the command line and in configuration file (~/.config/dspdfviewer.ini), view PDF files using the Poppler (a library for rendering PDF files). The app has many experimental features, “default” is disabled, to control using mouse and/or keyboard.
