Tools 9-Patch-Resizer

A resizer tool to automaticaly resize png files and 9 patches in several densities (previously hosted on https://code.google.com/p/9patch-resizer/)

Build Status


To get the latest build (.jar or .exe file), check the release page on the github project: https://github.com/redwarp/9-Patch-Resizer/releases

The .exe file is just a wrapper around the executable .jar file, use it if you don't feel comfortable with a java archive ^_^

What is it exactly?

Let's face it : juggling with densities for Android is a bit of a pain, especially when dealing with 9 patch png.

And then comes this tool, that takes a xhdpi PNG file, or 9.png file, and generates ldpi, mdpi and hdpi png files automatically.

As simple as drag and drop can get.

And here is the changelog

Current version : 1.4.2
