Scene description language

Scene is described by a sequence of statements, separated by newlines or ";". Statement names are case-sensitive. Four statements are supported:

at X Y

Sets current origin to the cell with coordinates X, Y. Used by the following rle commands.

-- TEXT

Defines description text. Several lines may be defined. Text can not contain semicolons (;).

PATTERN_RLE

Puts given RLE code at the current coorinates. Rle code is a standard format, used by many cellular automata simulators.

• b encodes empty cell,
• o - alive cell,
• $ - new line,
• numbers encode repeat count of the following character.

colors COLOR-LIST

Sets current color palette. When adding patterns, new cell colors are taken from this pattern. COLOR-LIST can be either a ":"-separated list of any CSS colors, or the text "default". In the latter case, pattern is returned to the default. Example: colors red:#00ff00:rgb(0,0,255).

Effect of the at and colors statements lasts until they are redefined. Additional spaces and empty lines are ignored.
