Bmp2Cvi v2.# by ssjx (https://ssjx.co.uk)
=========================================

Bmp2Cvi can convert uncompressed BMP files into smaller 4 colour pictures better suited to the Cybiko handheld computer.

Usage
-----

bmp2cvi myfile.bmp

This will result in a file called 'myfile.cvi'

By default, ordered dithering is used, to use no dithering or to use diffusion:

bmp2cvi -nodither myfile.bmp

bmp2cvi -diffuse myfile.bmp

Diffusion can give a better image but can result in larger files.


Getting your bitmap in the correct format
-----------------------------------------

The BMP file needs to be 24bit and have a resolution of 320x200 or lower. The width should be divisible by 4.
