Hi, |

Happy New Year!!! |
4 |
|
5 |
the programmable pocket calculator "DM42" offers OFFIMAGES, |
6 |
which will be displayed, when the calculator is switched off. |
7 |
|
8 |
The display is pure black and white. |
9 |
|
10 |
For displaying (the illusion of) different shades of gray, one need |
11 |
to convert the colored image into a so called "dithered" black and |
12 |
white image (newspapers often use this trick). |
13 |
Since -- in difference to the newspapers -- the pixels all have the |
14 |
same size and can only be switched on or off only a few dithering |
15 |
methods can be applied from which I want to choose the best suited |
16 |
for a certain image. |
17 |
|
18 |
The only problem: Which software can do this kind of conversion? |
19 |

Thanks a lot for any help in advance! |

Cheers |
