Convert PNGs into RLEs Easily on Any OS with PNG2RLE
Unlike other operating systems, Android uses its own graphical image formats. Most of the images use in the OS are PNGs, but there are some devices that use the RLE image format for their kernel logos. This format provides a pretty good compression ratio and is very fast. Sadly, converting a PNG file to RLE isn’t easy and requires some tools. There are plenty of them, but not many can be described as cross-platform and don’t require ImageMagick to work properly.
If you are looking for a simple tool able to convert PNG files into RLE files in just few seconds, XDA Senior Member alireza7991 has created something for you. PNG2RLE is a text tool that converts raw PNG images into the kernel logo compatible format on almost every OS. It works like a charm on Linux, Windows, and even directly on Android.
Usage is very simple and straightforward. You need to execute the binary and put a path to the input and output files. As a result, you’ll get a RLE file ready to be placed in your device’s ramdisk. In case of any problems, you can read the provided ReadMe file that can be found in one of the files on Github, because PNG2RLE is an open-sourced project.
Don’t leave your kernel with a stock and ugly kernel image. Replace it with your favorite PNGs using PNG2RLE. You can get started by visiting the PNG2RLE original thread.
