Type & code
ANSI blocks
Half-blocks with two inks per cell and a terminal palette.
Controls
- cell
- Side of one half-block in source pixels. A terminal cell is two of them, one above the other
- palette
- Sixteen is the CGA inheritance the BBS scene was drawn in; 256 adds the xterm cube; full drops the limit and leaves the block grid
- dither
- Mixes an ordered threshold in before the colour is matched, so sixteen colours stop cutting gradients into slabs
- contrast
- A number from -1 to 1, 0 by default.
