Hi,

I guess some of you already know bout the 'DUOKAN' system from China.

What I want to do is to change its boot-up screen. I already found the boot-up screen image file which is in raw dump format of framebuffer of kindle. There are total 600x800 4-bit HEX characters.

My question is how can I convert a picture of 600x800 to the format of raw data for framebuffer. I googled a lot and there is no direct answer. I am thinking writing a python script to do it, but to avoid unnecessary efforts, I am wondering if there is any tool which can do it.

Thanks a lot.

I attached the raw screen file.
