This application can compose images out of a whole directory of images in a mosaic-like fashion.
This application can be very CPU intensive and also consume a lot of memory. Sometimes exceeding the JVM default maximum allowed amount. To overcome this, launch the application with the java argument -Xmx4g for example allowing 4GB of memory to be allocated.
This application can also be used without the GUI.
Usage: java [-Xmx4g] -jar PicturePixels.jar nogui run|info <target image> <input directory> <number of duplicates allowed> <number of subtiles> <subtile match size> <tile render size> <output file>
