Pdf document viewer specialised for doing presentations with beamer. This has been heavily inspired by pdfpc, but built using Qt5. Key features :
- One window for public, one for presenter with additional information (slide numbering, timer, text annotations, next slide).
- Pdf render cache and prefect system, to enable very fast slide changes.
- Slide timing summary for training.
PdfTalk was initially developped to fit my use case : simple, fast, and tiling-window-manager-friendly. pdfpc has more features and is more actively supported.
Requirements to run pdftalk
:
- Qt >= 5.3
- poppler library with Qt5 bindings
Installing libpoppler-qt5
on Debian/Ubuntu should be sufficient to run the precompiled binary in the release section.
Compilation from source requires a C++11 compiler and the header files for the required libraries. Steps :
qmake
make
Starting the presentation tool is simple:
pdftalk <pdf_document>
PdfTalk creates 2 windows : one for the spectators with the current slide, and one for the presenter with neighbouring slides, a timer, and slide numbering.
The windows can be placed on the two screens (use s
key to swap them), and can be made fullscreen (f
key).
Navigation is standard (→
←
space
home
end
keys).
The timer can be paused/resumed with p
, and resetted with r
.
A summary of slides timing can ge written to a file after the presentation using t
.
For each visited slide, it indicates when the slide was first reached, and the total time spent on the slide.
The generated file is a simple text file containing a table of tab separated values.
The presenter window can show text annotations.
It follows the old pdfpc model: a text file named <pdf_file_name>.pdfpc
in the same directory as the pdf file.
The text file can easily be generated using the pdfpc-latex-notes package.
A copy can be found in test/
.
FIXME annotation handling:
- pdfpc file format has changed over the years. Most recent seems to be JSON. related issue.
- there is a pdfpc.sty package in latex-extra. Seems to default to PDF internal annotations.
- revisit using pdf annotations ? pdfpc handling here. And/or old commit when I tried using them.
Some additional functionnality would be useful:
- Go to page/slide n
- Presentation slide overview mode ? Need to choose page sizes. Toggle with 'o' ? Could replace "go to n".
Maybe useful:
- Disable screensaver ; no standard way to do this.
- Spread windows on multiple screens on startup ?
Will not support:
- Support for durations (no animations for now)
- Support for Poppler Rotation flags (don't know when it matters)
- Movies
- Transitions / animations
