RLE Decoder
RLE Compress
===========
The RLE Decoder is a part of LVGL that is responsible for decoding RLE
compressed original LVGL binary files. The file name suffix is always set
to '.rle' and the file header is added with another 64-bit value that
includes a 32-bit magic number and 32-bit RLE information.
LVGL provides a custom RLE compression method. It can be used to reduce binary
image size. The RLE compression is a lossless compression method.
The LVGL's built-in binary image decoder supports RLE compressed images.
The decoder supports both variable and file as image sources. The original
binary data is directly decompressed to RAM, and further decoded by LVGL's
built-in decoder.
