About the splash screen image

The image encoding format

Pigeon's splash screen image uses RLE (Run-length encoding) data format.Other parts do not follow this encoding.
Please note that it is not a standard RLE structure.
Each RLE data consists of 16-bit data (2-bit color index and 14-bit pixel continuous length).
The binary format is: CCLL LLLL LLLL LLLL
CC is a color index value, which ranges from 0 to 3. Support four colors in total.
LLLLLLLLLLLLLL is the length of consecutive pixels, and its bit length is determined by the highest bit of the number of pixels on the screen.For example,Pigeon's screen resolution is 80x160. 80x160 = B110010 00000000.Its binary length is 14 bits.If you want to use it at other resolutions, this part may need to be recalculated.

Customize

You can use the img2rle.py script to generate your own splash screen image.
