Automatically generate images at different Android resolutions

Automatically generate images at different Android resolutions

It is troublesome to process the icons for Android screen resolution adaptation, which makes it a waste of time to make images of different sizes on the UI and is prone to errors. Therefore, I wrote a tool in Python to automate image processing, the UI only needs to prepare an image with a resolution of 1080*1920. Images with other resolutions are automatically generated.

Import OS. pathimport sysfrom PIL import Image "automatically generates App images of different resolutions. uidesign: 1080*1920 resolution images, which are placed in the drawable-xxhdpi directory, automatic Generation of other resolution images "" _ author _ = ['"Xitao ":
