The grid consists of squares, like graph paper. Objects should be placed on the grid lines whenever possible, but exceptions are possible.
Any font can be used, but, like a typewriter, only one font size is available. The font size is adjusted to the grid so that the text fits between two horizontal grid lines.
For certain applications such as formulas, a monospaced layout can be used, where a character is exactly half a grid square wide.
Two different stroke widths can be used. One of them corresponds approximately to the stroke width of normal font and the other of bold font.
To ensure good visibility of points, the radius depends on whether the point is placed freely, on a normal line, or on a bold line.
A second color can be used for highlighting.
Strokes can be dashed.
Text can be slanted.
Objects can be inverted.
Inverted objects should mainly be used on opaque fills only.
Three different fills are possible:
Fills can be partially or completely outlined with strokes.
The style options should be used sparingly:
