Luban is an image compressing tool for android with efficacy very close to that of WeChat Moments. This project Luban-Py ports its algorithm to Python and offers an executable program for Windows.
Description for Luban
With the ever increasing resolution of smartphone cameras, image compression has become a rather important concern.
Although there are already a lot of writings on the internet on the topic, a great number of possible scenarios still have to be though of, like unsuccessful compressions, too small pictures (eg. for profile pictures) or too bad image quality.
Naturally, the first idea was to see how the WeChat, the app giant manages this task in action. To gather data, 100 images with different resolutions were sent through WeChat Moments, then the compressed images were compared with the original ones. Luban's foundation is the result of this analysis on WeChat's compression method.
Because the process was analyzed backwards, Luban's efficacy is not yet exactly the same as that of WeChat, but the results are already very close to what WeChat Moments' image compression produces.

| Methods | Description |
|---|---|
| load | load the image |
| setTargetDir | set the path where compressed images are saved |
| compress | compress the image if its size is greater than the threshold (set by self.ignoreBy) |
- Drop one or more images to "Drop your images here.bat"
In this way, you can rewrite "luban.py" to meet your requirement. However the images have to be in the same folder with the .bat file.
- Drop one or more images to "compress.exe"
In this way, the images can be from anywhere.
The compressed images will appear in the folder "target" under the same path with the original images.
