Was playing around in BlitzMax and I wanted to see if I could convert pictures into "Goober" format. Goober Format is a monochrome-based four color scheme which uses a multiplication of a certain color over a grayscale to create said color scheme.

The images used are from Windows 7's default Sample Pictures library.

Goober's Color:
(192,255,128)

Grayscale components:
[0,85,170,255]

Available Colors:
0: (0,0,0)
1: (64,85,43)
2: (128,170,85)
3: (192,255,128)

Because I wasn't using any shaders to accomplish this (software rendering), it was really REALLY slow to compute with larger resolutions. As such, I shrunk them down to achieve a higher framerate.





The changing in brightness is a "bias" added to the program I was using. As I held the up and down arrows, it added or subtracted this bias, allowing me to view these pictures in Goobervision at varying levels. This works with any color, by the way.



Added dithering for some more shading. This allows 8 shades instead of four.


Added changing of hue (although the saturation has been omitted so it just shows straight up color, but still pretty neat).


Bye bye now.
