We can see the following situation:
According to the above rules, we can see the ambiguous stippling wave. It is clear that we find a
method to eliminate wave phenomenon. But now another problem appear, how to find the best modula-
tion sequence for all gray levels, so the adequate trade-off are needed.
* Maximum Contrast and Attribute Emulation
When color text converts to mono LCD panel mode, remapping gray levels between foreground
and background are probably to the same gray level. It is difficult to recognize text forms on the screen.
We provide user 'maximum contrast' option to enhance LCD display contrast. The operation as follow-
ing:
When foreground attribute (G0,R0,B0,I0) is larger than background attribute (G1,R1,B1,I1), we
set (G0,R0,B0,I0) = (1,1,1,1) = 63 gray level, (G1,R1,B1,I1) = (0,0,0,0) = 0 gray level.When
(G0,R0,B0,I0) = (G1,R1,B1,I1), we reverse the original attribute gray level.
There is another option called attribute emulation. The user enable the 'attribute emulation' func-
tion. Attribute Remapping does eight clear contrast automatically, so user can get the best looking in
the text mode.
