The idea of this project was given by Jeff Clark's Word Portrait on his website neoformix.com, which shows an image of Albert Einstein only consisting of the text "Genius". Fiete Botschen and I decided to take this image as inspiration for an university Computer Vision course project in 2015. We successfully implemented an algorithm which generates similar Word Portraits like the one from Jeff Clark.
Till 2015 this project was put on hold. In January, 2018 I started to refactore and optimize the code by using a summed-area table, which boosted the runtime overwhelming well. Furthermore I implemented some submodules based on this algorithm, which allows you to create images consisting of Triangles, Circles and Rectangles (and maybe more soon). Some examples can be seen below.
For the result above i used this Image of Albert Einstein with the free Font from www.1001freefonts.com.

- Qt (version 5.10)
If you installed Qt Creator IDE already you can easily open the project with the provided .pro file. Select the right Qt version and press configure. After that select Release as compile mode and press compile to build the program. For compiling Qt creates a folder outside the main directory called build-ArtWork-...-Release where the executable will be created. All possible render options can be set within an XML file. Therefor you do not need to recompile the program every time you changed some parameters.
Go to your built executable and open a terminal to run it via command line with. If everything works finde a help message should be printed.
./artwork [OPTIONS] <rendersettings.xml>
A help message is included by ./artwork -h or ./artwork --help and will print the following lines.
Artwork version 0.0.1, Copyright (c) 2018 Christoph Kreisl
Usage: artwork [options] <rendersettings.xml>
Options/Arguments:
-h --help Display this help text
-i iname Load the input image from a path denoted by "iname"
-o oname Write the output image with the name denoted by "oname"
If there is a file type it will be removed. Set output file type in XML
rendersettings!

You can use all image types which are supported by the Qt QImage class.
(tested on Ubuntu 16.04 04/17/2018)
Running the programm via command line (Power Shell) could be a little bit inconvenient, since you have to copy .dll files from Qt into your directory where your ArtWork executable lies. Because of that simply run it within Qt Creator. Command line arguments can be set by the following steps:
1. On the left panel in Qt Creator select 'Project'. The symbol is an open-end wrench.
2. Select 'Run'
3. Set your command line arguments
Finally build your program in Release mode and press run.
(tested on Windows 10 64bit 04/20/2018)
Via command line navigate to your folder where the programm is built. Qt creates an Artwork.app where your executable file is stored. You can run the program via command line with:
ArtWork.app/Contents/MacOs/ArtWork [OPTIONS] <rendersettings.xml>
If you successfully built the program a help message will be displayed. For more information check the Linux section.
