Making such a picture billboard is actually very simple
I wrote an automated script to generate this program
http://alist.lilikeji.top/d/hfs/ggp/run.lua
How to use:
First prepare a picture
Use the picture segmentation tool to cut (you can also PS yourself)
What I use is: picture segmentation -graphic toolbox -imgtool.net
Start processing
Then get these pictures
Upload these pictures to the Internet
I use information center / cloud data center / (liulikeji.top)
Create a folder that belongs to you
Click to upload
Select the file just now
Then right -click (copy the download link)
In this way, the URL of this picture (will be used later)
Put a 4x3 screen matrix
A single screen is 8x6
Connect with cable+modem on the back
Connect a computer at any position at the cable and connect
Turn on the computer
Download the file to the computer
wget http://alist.liulikeji.top/d/hfs/ggp/run.lua
wget http://alist.liulikeji.top/d/hfs/ggp/config.cfg
Open the config.cfg file (you can use external software or inside CC)
edit config.cfg
The default file is 4x3 billboard, which is 12 screens
Parameters of a single screen
Monitor_id is the ID of the modem link screen
http_url is the download URL of the picture just now
For example:
Each screen needs to be filled with these two values and different
If it is a 3x3 screen or more, you can choose to delete or add
After filling in Run.lua
Waiting for running
Then your directory will appear
This is the image file and code of each screen (boot operation)
Then restart the computer
You get a large screen
The subsequent replacement pictures only need to upload a set of pictures to the same position (the name is the same)
Then click the end button
Run Run.lua to update
In fact, let the screens in each list display different pictures
You can not even put the screen together and allocate different pictures
A computer controls a bunch of billboards
