plakativ
|
|
========
|
|
|
|
Plakativ is German for "striking" or "eye-catching" and comes from the German
|
|
word "Plakat" which means poster in English.
|
|
|
|
This software allows one to stretch a PDF document or raster image across
|
|
multiple pages that can then be printed on a common inkjet or laser printer,
|
|
cut and glued together into a larger poster.
|
|
|
|
Features
|
|
========
|
|
|
|
Plakativ allows one to create a poster using one of three different approaches:
|
|
|
|
- I want a poster that fits into size X
|
|
- I want a poster Y times the input page page area
|
|
- I have Z pages of paper and want to print the biggest possible poster on them
|
|
|
|
Plakativ works on Windows, Linux and MacOS. It offers a GUI based on tkinter, a
|
|
command line interface and can be used as a Python module. Everything is inside
|
|
a single file.

Demo
|
|
====
|
|
|
|
|
|
|
|
[//]: # (To make a new Video, run:)
|
|
[//]: # (ffmpeg -f x11grab -framerate 30 -video_size 800x600 -i :0.0+41,46 -preset ultrafast -c:v libx264 -crf 0 out.mp4)
|
|
[//]: # (ffmpeg -i out.mp4 -ss 00:00:04.000 -r 2.5 plakativ%04d.png)
|
|
[//]: # (convert -loop 0 plakativ*.png +map -layers Optimize plakativ.gif)
|
|
[//]: # (gifsicle -b -O3 plakativ.gif)
|
|
|
|
The demo shows a user choosing between the three different ways to define the
|
|
poster size. Either by picking a size that the input will be fit into, by
|
|
multiplying the area of the input page or by maximizing the poster size, given
|
|
a number of pages one is willing to print on.

Installation
|
|
============
|
|
|
|
Plakativ is available from pypi: https://pypi.org/project/plakativ/
|
|
|
|
Thus you can just run `pip install plakativ` on your platform of choice.
|
|
|
|
For Microsoft Windows users, PyInstaller based .exe files are produced by
|
|
appveyor. If you don't want to install Python before using plakativ you can
|
|
head to appveyor and click on "Artifacts" to download the latest version:
|
|

|
|
|
|
Complex Layouter
|
|
================
|
|
|
|
Oftentimes there is a way to create a poster of a specific size with less pages
|
|
than would be needed with a regular arrangement of pages into rows and columns.
|
|
For regular poster sizes, a more complex layout can save up to 3 or 5 pages of
|
|
paper. If the regular simple layout and the complex layout require the same
|
|
number of pages for a particular poster size, then plakativ will fall back to
|
|
the simple layout. The following animation shows the complex layout that
|
|
plakativ chooses when asked to produce the largest possible poster using X
|
|
pages. The number of pages X can be seen in the center.

TODO
|
|
====
|
|
|
|
While basic functionality is implemented, lots of work remains to be done:
|
|
|
|
- help button
|
|
- changing units
|
|
- changing language
|
|
- make PyMuPDF dependency optional
|
|
- optionally, use pypdf2 to read/write PDF
|
|
- improve module interface
|

Comparison to similar software

==============================

|
PosteRazor
|
|
----------
|
|
|
|
http://posterazor.sourceforge.net/
|
|
|
|
PosteRazor served as the inspiration for this software. But in contrast to
|
|
PosteRazor, plakativ allows PDF documents as input and outputs PDF document
|
|
with the exact same quality as the input. It is thus not necessary anymore
|
|
to first do a lossy rasterization of an input PDF so that one can work with
|
|
PosteRazor.

pdfposter
|
|
---------
|
|
|
|
https://pdfposter.readthedocs.io/en/stable/
|
|
|
|
- no GUI
|
|
- cumbersome box definition
|
|
- no page borders for gluing
|
|
- superfluous empty pages
|
|
- only very simple layouter
|
|
- scaling by width/height instead by area makes doubling unintuitive
