#solid (predefined symbol)

Type	Readable	Writeable	Constant
bool	Never	In transformations, and in the final section of coloring algorithms	No

Transformations and coloring algorithms can set this predefined symbol to true to indicate that the pixel being calculated should have a solid color.

Before executing the transformations and coloring algorithm, Ultra Fractal sets #solid to false, so you won't have to write to it if you don't want a solid color for every pixel.

Example:

#solid = true
