ECHO -r : Specifies scale or size. The amount of pixels this value is set to will be the width of the gif.

ECHO -f : Specifies framerate in Hz. THe default is 15.
|

ECHO -m : Specifies one of the 3 modes listed below. The default is diff.
|
||||
ECHO -d : Specifies which dithering algorithm to be used. The default is Bayer Dithering.
|

ECHO -b : Specifies the Bayer Scale. This can only be used when Bayer Dithering is applied.
