Plakativ allows one to create a poster using one of three different approaches:
|
||||
|
||||
- I want a poster of size X
|
||||
- I want a poster X times the input page page area
|
||||
- I have X pages of paper and want to print the biggest possible poster on them
|
||||
- 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

The demo shows a user choosing between the three different ways to define the
|
||||
poster size. Either my picking a size that the input will be fit into, by
|
||||
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/img2pdf/
|
||||
|
||||
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 img2pdf 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.
