Temat: new RIP mode...?!?

Well,
if I remember correctly RIP uses Gr. 9 + Gr. 10 to generate a higher resolution (160x200 or even 160x238) and still having lots of colours. But afaik, RIP uses Gr. 10 for the colors and Gr. 9 for the luminances, thats 9 colors each with 16 luminances. The result is a nice resolution but quite often strange colours...

Hmm, how about that idea - mix Gr. 11 with Gr. 10, where Gr. 11 gives us 16 colors and Gr. 10 gives us the luminances. To reduce flicker we will only use 8 of the available nine luminances in Gr. 10 (thus the first and last lum. of Gr. 10 are the same => black) and to further reduce flicker we use luminance steps like in HIP mode: 00, 02,04,06,08,0A,0C,0E...

The result would / could be 16 colors each with 8 luminances, thats a total of 128 colors (this should also be easier to convert from ST, Amiga or PC, I guess), with a resolution of 160x200 or 160x238...

Now, would that be possible ???    (And err, if not, why not?)    -Andreas Koch.

Hi!

The trick is that GR.10 lines can be shifted by a half of the pixel and this makes the screen look better. Your proposal would yield 80x200 resolution. Please correct me if I am wrong.

Well,
thats why I want to mix Gr. 11 with Gr. 10 - so Gr. 10 is still there for the higher resolution. The difference to original RIP format would be using Gr. 10 for the luminance (not Gr.9) and Gr. 11 for the colors...  -Andreas Koch.

Andreas,

You are right, sorry for my post that is good for nothing.
