In order to keep the LPL website looking consistent aesthetically, we use the Gem file pxlsrt to generate images. However, because command line options are not very well documented, you may have to experiment with various thresholds.
We like both the smart and kim algorithms for generating images. However the default values need to be overwritten.
The syntax for pxlsrt assumes INPUT is a .png file. JPG files will not work.
pxlsrt algorithm INPUT OUTPUT
Below are some sample commands we ran. With Kim you set the thresholds with -v but for Smart you use the -t flag. In the smart example below, the -v flag sorts vertically.
pxlsrt kim -v 80 newsroom.png newsroom_kim_80.png
pxlsrt smart -v -t 80 newsroom.png newsroom_uniq_v_80.png
If you choose to experiment further, you can change the method with the -m flag. You can sort pixels based on colors, random values, along different colors etc. pxlsrt help ALGORITHM will give you more information.
