amiga2rgb is a small program to convert modern RGB images (jpeg, png, etc.) to an IFF/ILMB tailored for the Amiga 500.

How to use

Rgb2Amiga [-p] [-d] [-s ] [-c ] -o -i [--] [--version] [-h]

Where:

*   -f <format slection>,  --format <format slection>
	Save as iff-ilbm (default) or png-gpl (PNG + Gimp palette).

*   p <scale>,  --preview <scale>
 	        Open a window to display a scaled preview. Defaults to no preview.

*  -d,  --dither	
	Use dithering.

*   -s <string>,  --size <string>
	Targeted size in WidthxHeight format. Defaults to "320x256"
	Optionnal suffix: '!' ignore the original aspect ratio.

*   -c <string>,  --colors <string>		
	Number of colors to use. Defaults to "32".
	
*   -o <string>,  --output <string> (accepted multiple times)
	(required)  Output file.

*   -i <string>,  --input <string> (accepted multiple times)
