In addition to those listed above, you can specify these standard X
resources as command line options: -background, -bordercolor,
-borderwidth, -font, -mattecolor, or -title
By default, the image format of `file' is determined by its magic
number. To specify a particular image format, precede the filename
with an image format name and a colon (i.e. ps:image) or specify the
image type as the filename suffix (i.e. image.ps). Specify 'file' as
'-' for standard input or output.

安装gaps：
sudo apt-get install python-tk
git clone https://github.com/nemanja-m/gaps
cd gaps
pip install . -i https://pypi.tuna.tsinghua.edu.cn/simple
Usage: gaps run [OPTIONS] PUZZLE SOLUTION
Run puzzle solver.
PUZZLE is the input puzzle image with square pieces.
SOLUTION is the output image file for solved puzzle.
Examples:
$ gaps run puzzle.jpg solution.jpg --size=32 --generations=100
--population=1000
Options:
-s, --size INTEGER Size of single square puzzle piece in pixels.
Autodetected if not specified.
-g, --generations INTEGER The number of generations for genetic algorithm.
[default: 20]
-p, --population INTEGER The size of the initial population for genetic
algorithm. [default: 200]
-d, --debug If enabled, shows the best individual after each
generation.
-h, --help Show this message and exit.运行gaps
gaps run ./flag.png resolve.png --generations=20 --population=200 --size=40
montage ./files/*.png -tile 30X20 -geometry +0+0 flag.png
gaps run ./flag.png resolve.png --generations=20 --population=200 --size=40
gaps run ./flag.png resolve.png --generations=400 --population=400 --size=40
运行完成后，可以看到，虽然图片边缘的处理还有些问题，但是图片主要的内容都已经显示出来了
